Citroen C4 does not start: possible causes, ways to eliminate the breakdown. How to install a Lifan engine on a Ural walk-behind tractor - adjusting valves Technical characteristics and prices for engines

Citroen C4 is comfortable, elegant, in all respects modern car... The manufacturer presents diesel and gasoline options with automatic and manual transmission. The French made perfect car both in terms of technical characteristics and aesthetic. But, despite this, the owners face problems during operation - sometimes the Citroen C4 does not start. Let's take a look at the root causes and find out how to fix these issues.

How exactly does it not start

Many car owners who have encountered similar problems write hundreds, if not thousands, of messages complaining that the engine won't start. But in order to understand exactly what is with the motor, you need to find out all the symptoms.

There are usually not many possible options... So, it happens that the driver, as usual, turned off the engine that had been working normally before, parked the car, and in the morning his Citroen C4 would not start. It also happens that the motor starts, but this takes a little longer than usual. Sometimes the internal combustion engine can work normally, but suddenly it stops and does not start anymore. They also often complain that the engine starts and immediately stalls.

These are not all breakdown options. Often, owners complain that the engine shoots or sneezes when starting. It is also not uncommon for the Citroen C4 to not start, the starter turns, but at the same time the car starts up perfectly in tow. Experts are also faced with such symptoms when the car did not even go anywhere, but suddenly stopped starting.

Knowing how the engine behaves, you can understand at least approximately what is wrong with the engine or with other auto systems.

Typical malfunctions

If the Citroen C4 won't start, don't panic. The success of the repair largely depends on how quickly and how well it will be possible to find weak link... To better understand the whole essence of possible renovation works, consider what can break.

Injection

It is possible to single out the malfunctions associated directly with the injector. With such breakdowns, the car does not start either cold or hot. The “Check Engine” lamp on the instrument panel will light up. Less often, the engine runs when the light is on, but at the same time it will not start well, and the operation will be extremely unstable. Most often, injectors of this manufacturer are clogged. The ECU fails. These nodes should be diagnosed first if the Citroen C4 does not start.

Ignition

Also, very often problems with starting are associated with the ignition system. Here possible breakdowns more. Usually the reasons lie in the candles - they can be flooded with fuel. In this case, the engine starts up and immediately stalls, and after several attempts to start it stops even grasping. Rarely, but still there are problems with other components in the ignition system - this is the ignition coil or module, sensor crankshaft.

Fuel system

Starting problems can also be associated with poor or incorrect operation of the vehicle's fuel system. French motors can suffer from three possible problems:

• Hammered fuel filter... In this case, the symptoms will be as follows: the car grasps, but does not start, if it was possible to start, then the engine will be very unstable.

• You can highlight the malfunctions associated with the gas pump. The car will not start under any circumstances and in any condition.

• Fuel rail pressure. If it is not enough, starting the engine will be very problematic. There is also a lack of cold and hot start, unstable operation.

Engine

Well, at the end, you can single out the motor itself as the cause of the problem. Here is the widest selection of possible options. The most common cause is poor compression or misaligned valve clearances. With such problems, high-quality diagnostics are needed, otherwise it will be very difficult to determine why the Citroen C4 Picasso will not start.

How to bring life back to the car?

If the engine stalls and does not start, you need to find and fix the breakdown. Let's see what is included in the list of diagnostic measures. In fact, many operations can be done by hand, without specialized tools.

When the starter turns, but there is no effect

If the starter turns, but the Citroen C4 does not start, then you need to make sure that the gas pump works in the car at all. In most cases, a working gas pump can be heard. Most often, the sound of its operation can be heard near the back sofa. There will be a characteristic buzzing sound when the device is operating.

If the pump does not function, then experts recommend checking the integrity of the fuses, as well as the fuel pump activation relay.

It will not be superfluous to check the ECU relay. If the fuses are in good condition, then you need to find out if the relay turns on. Its performance can be determined by a characteristic click. This click will be heard when the vehicle ignition is turned on.

Fuel system diagnostics

If the Citroen C4 stalls and won't start, then the problem may be somewhere in the fuel system. If the pump is working properly, then you need to make sure that there is pressure in the rail. For this you need a pressure gauge. Testing in the field is also possible. There should be a spool on the ramp - press it. If the pump is running, then the pressure in the rail will be within 2.8 atm.

If you press the spool, the fuel stream from it will be even. In this case, the pressure must be constant. If the pump functions quite normally, but there is no pressure in the rail, then you need to check for the presence of fuel in the tank, clogging of filters, and patency of the lines.

Pressure regulator

Injection motors work under a certain pressure, which is pumped into the rail by a gasoline pump and is adjusted by a special pressure regulator. To diagnose it, disconnect the hose through which the fuel flows into the tank. With the hose disconnected, the ignition is turned on. If fuel is supplied from it, then the problem has been detected, and the regulator must be changed.

If this malfunction is caught on the road, then you can muffle one edge of the regulator or pinch the tube. Thus, you can get to the place of repair.

What else should you pay attention to?

If there is pressure in the rail, there is gasoline in the tank, then the car's ignition system should be diagnosed. It is recommended to use a special arrester for diagnostics. If a spark is present, but the Citroen C4 car does not start, then the spark plugs are checked visually, and then with special equipment.

Throttle valve

If this node does not work correctly, then quick start and stable work no need to wait. Breakdown can be diagnosed different ways... It is necessary to unscrew the supply pipe, inspect the body and the damper itself visually - it is possible that a workout or any mechanical defects will be visible.

When the motor is not running, the damper will be closed. If it cannot close normally, then you need to clean the throttle.

Motor starts and stalls

If a Citroen C4 car starts up and stalls, then, most likely, everything is in order with the engine and its other systems, and the problem lies in the immobilizer. Diagnosing this malfunction is simple - usually on dashboard the lamp will be on or flashing. If the connection between the chip on the key and the immobilizer is lost, then you can forget about the normal engine start.

To solve the problem, you will need to use special equipment, which is on the official dealer. Otherwise, you can replace the key with a spare.

Starter clicks, no effect

If, when you try to start, the Citroen C4 does not start and clicks at the same time, then we can say that the retractor relay is faulty. It needs to be replaced. After replacement, the starter motor will be able to work normally. It is also worth checking the condition of the battery. With a discharged battery, the current will only be enough for clicks.

If the Citroen C4 does not start, the starter does not turn, then you should check the wire connections directly to the starter, as well as the relay.

The starter may not show signs of life with poor "weight" or no contact. But it will also not be superfluous to carry out diagnostics with a scanner. The car is completely electronically controlled, and it is possible that there are errors in any of the components.

Doesn't start on hot or cold

In the first case, malfunctions associated with the coolant sensor can be distinguished. The sensor should be replaced. If there is no cold start, then all of the above is possible.

Diesel versions of "Citroen C4"

Diesel Engines have a different principle of operation, unlike gasoline ones. And the reasons for the poor launch are slightly different.

For diesel engines, high compression is important. If, for a number of reasons, the compression has decreased, then the air in the combustion chambers will not be compressed enough. And if the air is not compressed, it will not heat up and the fuel will not be able to ignite.

It is not uncommon for start-up to be affected by a variety of glow plug problems. Conventional diagnostics will not help here, since there are no visible problems on a hot engine. But it will be problematic to start the engine on a cold one with faulty spark plugs. Often, the reasons for the breakdown lie not in the candles themselves, but in the electronics that control the operation of the glow plugs.

There may be problems with fuel system... If any small particles get into the diesel injectors, the engine may not start. In this case, you need to pay attention to gray smoke when trying to start. If it is, then fuel is supplied to the cylinders, but the mixture does not ignite for some reason.

If the diesel Citroen C4 does not want to start in cold weather, then this may be due to fuel. It contains paraffin. In winter, this fuel thickens. In this state, it cannot pass through the filter and, naturally, is not fed further. You need to use winter diesel fuel.

Often there are problems with the fuel line. If there are cracks in it, then the fuel will escape from the system. The main thing to remember is that if smoke is visible from the chimney when starting, then the fuel enters the cylinders. If there is no smoke, then it is worth diagnosing candles or compression.

Conclusion

So, we found out why the Citroen C4 car may not start. As you can see, the problem can be of a different nature. If this gasoline engine, then first of all you need to inspect the pump and candles. Well, diesel is a little more complicated. After all, if the problem is in compression or injectors, you will not be able to fix it yourself.

Let's start with malfunctions when the starter does not turn. Everything is simpler here than a steamed turnip.

If the activation of the solenoid relay is not audible, we check whether + when the ignition key is turned on comes to the black and yellow wire. It is better to check at the point of contact on the starter retractor relay. It is not easy to get to it, but it is possible. The starter for Lifan Solano is located on the far side of the engine, under the intake manifold.

Check all fuses, there is a fuse assignment in the instruction manual. First of all, see the two 30 amp fuses in mounting block salon. In Solano, to see the mounting block, you need to lie with your head on the driver's mat and look up.

These fuses provide ignition. When they burn out, not only the starter does not work, so if everything works, then the reason is clearly not in them.

If there is no plus on the solenoid relay wire, and the fuses are intact, then the reason is either in the wire and unreliable contacts, or in the ignition switch. In this case, you need to check for the presence of a plus on this wire directly at the ignition switch.

If the retractor relay is activated but the starter does not turn... The brushes could be corny, it is solved by removing the starter and replacing the brush assembly. Check for positive voltage on the red wire going to the starter from the battery. This wire goes directly from the battery to the starter, but through the contacts on the mounting block under the hood!

These very contacts sometimes burn, remove the cover from the mounting block and check for traces of melted wires.

Another reason for an inoperative starter is the lack of mass on the engine. The negative wire is screwed into the front of the gearbox, be sure to check the reliability of its attachment and the quality of the contact. It is better to unscrew rusted contacts, clean them and tighten again.

The starter turns but the engine does not start

This also happens, here the troubleshooting goes in a slightly different direction. First of all, of course, sparking and fuel supply are checked. To work fuel pump can be blocked by the standard security system. Listen carefully, can you hear the operation of the fuel pump when you turn on the ignition?

If not, then try to arm and disarm the car with the standard key again. If it does not help, then in extreme cases, you can turn off the blocking of the gas pump. To do this, remove the heater control unit. To do this, remove the lining "under the tree" and unscrew the two bolts on the Lifan Solano. Everything else is fastened with snaps.

Below it is the BCM (body electronics control module). For convenience, it is better to remove it, it is fastened on two bolts under the key at "8". Three connectors are connected to the block - one long on top and two small ones on the bottom. We need a white connector on the bottom.

We find a violet-green wire in this connector, this is a permissive plus for the operation of the fuel pump relay. Feel free to cut this wire near the connector. The cut wire that goes into the bundle must be stripped and connected to the blue-green wire in the same connector. The blue-green wire is the wire on which positive voltage appears when the ignition is turned on.

That's it, now the gas pump will work regardless of the quirks and glitches of the security system. Of course, the function of blocking it will be lost in the event of an attempt to start the car with the alarm turned off.

Checking for spark and injector operation

If there is no spark, the engine will also not start. It is quite easy to check the claim, but an assistant is needed. Remove the rubber cap of the high voltage wire from the spark plug and pull it out slightly. That is, you need to raise the tip above the spark plug by 5-7 mm, no more, otherwise, if the spark has no place to go, the ignition module or control transistors in the ECU may burn out.

The tip is raised and ask the assistant to turn the starter with the ignition key. If there is a spark, you will hear clear clicks in candle well... Check all four cylinders in this way. If there is no spark, then the reason may be either high voltage wires or in the ignition module.

On the injectors, you can only check the constantly supplied plus 12v. on a blue-red wire. With the ignition on, each injector must have an on-board voltage of + 12V on this wire. If it is not there, then again we look at the fuses.

A constant plus is supplied to the injectors when the ignition is turned on, through the FS04 fuse and the main relay. There is both a fuse and a relay in the mounting block under the hood. Their names are written on the bottom of the lid, in English - main.

In the spring we take the equipment to the personal plot. Unfortunately, a situation often arises - the walk-behind tractor does not start. The owner must quickly determine the cause of the failure and correct the malfunction.

Starting gasoline and diesel units

The walk-behind tractor is a multifunctional tool. It is indispensable for home gardening. Attached equipment allows you to perform land cultivation, grass mowing, snow removal, cargo transportation, planting and harvesting.

The equipment is equipped with gasoline or diesel engines... Launch diesel walk-behind tractor and gasoline unit has differences. Therefore, it is necessary to analyze the reasons due to which the walk-behind tractor does not start, for each specific type of engine.

Before starting the walk-behind tractor, the equipment is prepared. It is necessary to make sure that all the parts are present, make sure that the mechanisms are securely fastened.

Mechanisms often refuse to work after winter. A long break causes a malfunction of the walk-behind tractor systems. Storage in a cold and damp place will result in the following breakdowns:

1. Oxidation of contacts.
2. Violation of wire insulation.
3. Watering of fuel and oil.
4. Clogged carburetor jets.

Before starting a new walk-behind tractor, check all connections, clutch cable, reverse and gas. The movement of the cables should be smooth, effortless. Do not start the unit if there are clamps and twists of the harness threads.

During the first start, be sure to check the oil level in the crankcase. Lack of lubrication will damage the piston group. The crankshaft rotates up to 1400 rpm at Idling... A couple of seconds are enough for a scuff to form on the surface of the cylinder.

Old oil can cause engine failure. At the same time, the walk-behind tractor smokes exhaust gases white... Begs complete replacement oils.

It should be borne in mind that the walk-behind tractor does not start well with an insufficient amount of oil. Watch this parameter before starting the carburetor and diesel walk-behind tractor. On some models, the protection is set to a low level. The sensor blocks the start and the unit stalls.

It should be remembered that each type of engine requires a specific brand of gasoline. For two-stroke motor fuel is prepared separately. The fuel mixture consists of gasoline and oil. The amount of ingredients is kept in strict proportion.

Purchase gasoline for walk-behind tractors at gas stations. The service life of the machines directly depends on the quality of the fuel. You should not start a walk-behind tractor on poor gasoline.

Repair of units and mechanisms

Starting a diesel walk-behind tractor after purchase can be difficult. The fact is that air enters the fuel supply system. If long scrolling (starter) fails to start, then release air locks... To do this, open the diesel supply valve and unscrew all connections along the fuel channels. The end point of the purge is the nozzles.

To the engine internal combustion wound up, it is necessary to fulfill a number of requirements. Let's list them in order:

1. Training fuel mixture.
2. Fuel supply to the cylinder.
3. Ignition of the mixture.
4. Exhaust gas release.

The fulfillment of the listed conditions guarantees the start of any motor.

Difficulties in starting indicate a malfunction of components and mechanisms. The success of the repair depends on the correctness of the diagnosis. If defects are found, they are engaged in the repair of a diesel walk-behind tractor. Maintenance and minor repairs can be done on your own. You will need a set of keys, locksmith tools and skilled hands.

At the stage of preparing the fuel mixture, the following incidents are possible:

• air filter does not allow air to pass through;
• the hole in the tank lid is clogged;
• the fuel supply path is clogged;
• the carburetor is broken.

After a series of unsuccessful launches, it is useful to unscrew the plug. The working part can be flooded with fuel. We dry the part. Next, we pump the cylinder through the hole. We twirl the candle and start it up again.

If the spark plug is dry, it means that no fuel enters the combustion chamber. Let's take a series of steps to restore the feeding system:

• drain old gasoline;
• rinse the tank;
• clean the filter from dirt;
• blow out the fuel supply hose;
• blow out the carburetor jets;
• fill the tank with clean gasoline;
• open the tap;
• clean the airway in the lid.

Ignition system malfunctions

The engine will not start if there is a malfunction in the ignition system. Why is this happening? Sources of failure can be magneto, high voltage wire, cap and spark plug. By visual inspection, they check the cleanliness of the parts of the ignition system. Dirt and moisture cause high voltage breakdown to the case. The absence of a spark occurs when the cap has poor contact with the center electrode of the candle.

A weak spark indicates poor spark plug performance. It is necessary to check the gap and condition of the electrodes. The gap is checked with a feeler gauge. It is usually 0.8 mm. If necessary, remove fumes from metal parts and insulator. Replacement of the spark plug is recommended.

Parts condition piston group affects the readiness of the motor as a whole. They work in difficult conditions... The rubbing surfaces heat up under load. The cylinder, piston and rings are responsible for an important indicator - compression. A low cylinder compression ratio will indicate replacement parts.

You should also check the inlet and outlet valves. They should fit snugly against the saddles. The muffler is the last point on the route of the exhaust gases. Combustion products are gradually deposited on the walls of the muffler, and the engine stalls. For normal passage exhaust gases the walls should be periodically cleaned from carbon deposits.

Experts advise to adhere to all manufacturer's recommendations. Do not overload the unit.

Fulfillment of all requirements will extend the service life of the mechanisms.

Before starting work, the owner must familiarize himself with the operating instructions.

Motoblocks Lifan belong to the means of small mechanization, which are widely used in agriculture... Their popularity is based on many factors, including relatively low cost and high technical and performance indicators.

The walk-behind tractor itself is a fairly simple design, where the engine plays the most important role. The quality of the processing of land holdings, as well as the efficiency of this very work, depends on how powerful this unit will be.

1992 is considered to be the date of foundation of the company. From that moment to this day, the company has experienced many difficulties associated with the period of formation, which allowed it to gain the necessary experience. At the moment, Lifan is considered one of the leading companies in China in this market segment.

The main specialization of the company is production passenger cars issued under the trademark of the same name. In addition, the organization's specialists are engaged in the manufacture of motorcycles, scooters, buses, etc.

In 2006, the company enters the world market, presenting its first Lifan sedan 520. Later, in 2008, another premiere took place - this time, the corporation releases the second representative of this lineup, i.e. Lifan 620.

In the same 2008, a partnership agreement was concluded with American colleagues from AIG, Inc. The result of this cooperation was the emergence of a joint venture for production.

Since 2010, Lifan Motors is considered the only private car manufacturing company in China. In general, the export share of cars of this brand is 11.38%, which is the second result in the country.

A garden sprayer will be a suitable unit for supplying plants with water, it will significantly save you time and effort, so buying such a device will be a really profitable investment for absolutely any gardener. you can familiarize yourself with the sprayer Moroleks.

Special units allow you to remove snow faster and in large volumes than manually with a traditional shovel. By clicking on, you can familiarize yourself with the technology of making a snow blower with your own hands.

In the spring, when it is time for planting seedlings, planting seeds and seedlings, the most laborious work during this period is planting potatoes. Planting potatoes can be done quickly and efficiently.

The broad pace of development has allowed us to significantly increase its representation around the world. In particular, over 165 factories were opened in America, Africa, Europe and Southeast Asia. After receiving the appropriate certificate, Lifan cars began to spread widely in the countries of the European Union.

The popularity of these motors among summer residents also explains the fact that many people prefer to install engines of this brand on their walk-behind tractors.

Like any other technical unit, in Lifan engines there are certain operational problems. This is not due to the poor quality of the motors, but to certain circumstances, which, quite often, are associated with the consumer himself.

Perhaps the main problem is as follows - the Lifan walk-behind tractor does not start. There may be several reasons:

• Poor fuel supply to the tank - to fix it, you need to open the fuel valve and pour fuel into the crankcase.
• Complete lack of fuel supply to the tank - you need to clean the air filter or the fuel cock.
• There is no spark - in this case, the main reason is the failure of the high voltage coil. The only way out is to completely replace the failed part.

In fact, this is how the main repair of the Lifan engine for the walk-behind tractor is carried out with your own hands. In principle, the instructions for the engine provide all the detailed information regarding possible breakdowns, as well as methods for their elimination.

Motoblocks Lifan, spare parts for which can be purchased from official dealers, have certain requirements for components. In particular, the manufacturer advises using only those parts that are produced by Lifan itself when carrying out repairs.

How to install on different models?

The specificity of these engines is such that their installation on domestic walk-behind tractors can be accompanied by a number of problems. To prevent this from happening, consider a few basic cases.

Installing the Lifan engine on the Agros walk-behind tractor:

• The complexity of installation on the Agros walk-behind tractor is that a conical shaft is located on the native engine of the walk-behind tractor, and a cylindrical shaft on Lifan. To fix this, you need to shorten the motor shaft a little, and then install it on a metal plate.
• The clutch basket of the walk-behind tractor will also have to be slightly corrected - the part that is worn on the engine output shaft must be re-sharpened. Instead of the conical shape of the inner half-disk, you need to grind a cylindrical one.

Installing the Lifan engine on a walk-behind tractor:

• Installation is quite simple, but the Lifan engine itself needs to be slightly raised above the frame body so that its parts do not come into contact with it. Of the alterations, a 10 mm thick metal plate can be noted, and several bolts were also re-drilled relative to the old engine.

Installing the Lifan engine on the MTZ 05 walk-behind tractor.

It takes place with little or no additional adjustment to the existing frame. Only some adjustment of the clutch basket is possible, but this is a rather minor procedure.

... The answer is quite simple - you need to start the engine, and then immediately proceed to cultivating the land, but at medium speed. In this case, it is impossible to run idle, because oil starvation may occur.

Oil change in a walk-behind tractor containing a Lifan engine should be carried out as follows:

• The engine itself must be hot, but before draining the oil from the crankcase, it must be turned off.
• Unscrew drain plug as well as the dipstick oil sump, after which the remaining oil should be drained. Then we reinstall the plug in its original place.
• We fill the crankcase with oil recommended by the manufacturer. Its level must be determined by the dipstick.
• We install the dipstick in its original place, and then we twist it all the way.

Many people ask - what kind of oil to pour into the engine of the Lifan walk-behind tractor? In general, each instruction directly indicates the name of the oil that it is desirable to fill. In general, SAE-30 summer oil or SAE-10W-30 multigrade oil is most often recommended.

Adjustment of valves

The valves on the Lifan walk-behind tractor will be adjusted as follows:

• Remove the cover under which the valves are located.
• To adjust, we need a screwdriver, a 10 box wrench and a razor blade.
• According to the passport, the clearance on Lifan engines is 0.12-0.02 mm.
