Middle age crisis. Middle-aged Crisis Diesel Engine on UAZ ZMZ 514 Hunter
The Diesel engine ZMZ 514 is produced on the Savolzhsky Motor Plant, and is the only representative of the Diesel of the entire line of the engines of this type. Initially, the power unit was intended for trucks manufactured by a gas group of companies, but the main mass of motors is bought by UAZ, for installation on its cars.
Specifications
Unlike gasoline fellow, diesel received increased technical characteristics than he became peoppreically. So, the power unit of the Volga plant received one of the best Bosch fuel systems. A polyclinic belt with a autotressum was also installed for the drive to work - TNVD, pump and generator. Modernized Common Rail Fuel supply system was installed on the engine
Consider, ZMZ 514 diesel and its technical characteristics:
The main part is established on the vehicles manufactured by the Ulyanovsky automotive factory, namely: UAZ Patriot (diesel), Hunter, pickup and cargo.
Maintenance of power aggregate
Service of the 514th FEA is characterized as for all domestic diesel devices. The intersavine interval is 12,000 km of run, but most experts and motorists converge to the fact that it is necessary to reduce this figure to 10,000 km to preserve and increase the resource.
During maintenance, consumables and oil are changing. To the first point refers - filter coarse and fine oil purification, as well as fuel filters. Depending on the operating conditions, it is also recommended to check the air filter, which after 15-20 km washes to be scored.
Special attention during maintenance, especially if it is carried out with your own hands, it is worth paying for nozzles to the state of nozzles, and the state of high pressure fuel pump.
The late repair of the latter can lead to a more serious breakage of the plunger pair, which will entail additional investments.
Engine repair
Repair the diesel engine of the 514th series is sufficiently difficult at home. So, you can carry out small repair, but the larger breakdowns are recommended to be repaired in car service.
At home, you can repair the fuel pump, replacing the glow candles, changing the valve cover.
The main problem with which motorists often face, becomes the trimming of a diesel power unit. In this case, it is often a problem may be hidden in clogging nozzles or a malfunction of the high pressure pump. Both parts for repair require special equipment, and therefore it is worth contacting the service station to eliminate the fault.
The cleaning and diagnosis of nozzles is carried out on a special bench, which will clearly determine the faulty item. As for the TNLD, it also requires special knowledge and skills that every car enthusiast has.
Often, the installation of the cooling system, which is simply changed at home. They include a thermostat and water pump. Thus, due to poor-quality spare parts, the thermostat can quite often be to climb, which leads to overheating of the engine or permanent operation of the electric fan. As for the water pump, it comes out from the system - when generating production on bearings.
The second option is the formation of leaks with under the shaft, which is easy to determine independently. The element change is simply carried out simply, it is necessary to remove the drive belt and unscrew several fastening bolts.
Output
Diesel engine ZMZ 514 was widely popular on vehicles produced by the Ulyanovsky automotive factory. The simplicity of construction, characteristic of all motors produced by the engineering engine, allows you to simply simply and easily repair the motor yourself. Maintenance of the power unit is carried out every 12,000 km of run.

The skirt of the piston of the barrel-shaped shape in the longitudinal direction and oval in cross section, has an antifriction coating. The large axis of the oval is located in the plane perpendicular to the piston finger axis. The largest diameter of the piston skirt in the longitudinal section is located at a distance of 13 mm from the lower edge of the piston. At the bottom of the skirt, an excavation is made, which provides the discrepancy of the piston with the cooling nozzle. Piston Floor Finger, the outer diameter of the finger 30 mm.
"ZMZ-514" is the trace of four-cylinder sixteenthly flaped engines with a 4-year-working volume of 2.24 liters. Initially, these motors were intended for use on passenger and commercial vehicles GA3, but as a result, they found their use on W3ach. Diesels "3m3-514" were installed on "Gag3li" only from 2002 to 2004, in rather limited quantities. Since 2006, the Ulyanovsk Automotive Plant has become a consumer of these power aggregates: they "stuck" first on the SUVs "UA3 Hunter", and then on "patriots", and created on their "UA3 cargo". But - just a few years: in 2015, the Ulyanovsky Automobile Plant finally refused to use the 3m3-514 motors. What are the reasons, and what are the features of this family - read further.
The main reason for the refusal of diesel modifications "Patriot" and "Hunter" is a negligible demand for these cars. It is not enough that the UAZ themselves do not shine giant volumes of sales, so also the demand for diesel equipment of Ulyanovsk SUVs was too small to consider their promising models. According to the management of the enterprise, the sale of diesel "patriots" was only 1% (!) On the total number of implemented machines.
It would seem, on such cars as the UAZ SUVs simply "ask" diesel engines. After all, there are serious advantages: an even more serious tons of stable permeability on the off-road, the possibility of "maximum" to load the car and trailer, fuel efficiency, high efficiency engine ... The dynamics is that the impression is created that the diesel "patriot" "lost" a couple of hundred kilograms compared to gasoline. All torque equal to 270 N * m, the diesel power unit produces already in the range from 1300 rpm to 2800 rp;; The diesel is easier and calmer "drags" not the easiest body of the UAZ. All this is the main indicators of utility. And utility for a jeep or pickup - above all. Those motorists who accounted for both gasoline and diesel "patriots", noted that diesel differ significantly for the better from gasoline.
However, despite all alterations and improvements, "3m3-514" "and remained the engine unreliable, capricious. Common, often arising problems with GDM and TNLD drives, small resource of the oil pump, gusts of the fuel line RTVD, cases of a sharp decline in thrust, falling out the valve dish Log in to the engine cylinder, unscrewing the plug of the KV, and even such a disgrace, as formed after 40 thousand mileage kilometers Cracks in the head of the cylinder block (casting defect), according to the manufacturer, were eliminated. But many "UAZOD" had a different opinion on this.
After equipping a new version of the motor - "3m3-514z2.10 CRS" - the electronic control fuel equipment of the Bosch Common Rail control fuel equipment, the engine has become less maintainable, and if they are maintained, only immediately with the nodes that are worth noticelessly, as well as more demanding on the quality of diesel fuel. The previously added problems were added to the problems with direct injection, constant metamorphosis with fuel pressure.
In the course of modernization, Boschess nozzles and an electric pump, ramp, incandescent candles were added; It was complemented by a Chinese turbocharger, and the engine still does not shine neither reliability or durability in use. Of course, such a reputation was perfectly affected by sales. In addition, the price of the diesel "UAZ Patriot" was more than 100 thousand higher than the gasoline version of this model.
The 3m3-514 family leads its history since the beginning of the 1980s, when the Volga engine plant began working on creating a diesel engine, based on a conventional carburetor motor for the Volga - "3m3-402.10". By 1984, a prototype of this power unit was created and laboratory and road tests were established, including on the auto-polygon us as part of a car GA3-24 "Volga". Operating volume - 2.45 liters, compression ratio - 20.5; With an aluminum cylinder block, an aluminum alloy pistons with a special spruelph and a barrel-shaped skirt profile, inkjet cooling of the pistons, an alarm device of the oil filter clogging, a candle of preheating. The continuation of this model, however, did not follow.
Only in the first half of the 1990s, specialists of the Volga motor plant returned to the creation of their own diesel engine for passenger cars and light trucks. For some reasons, they were tasked to make a diesel engine not just on the basis of gasoline "3m3-406.10", but also having a maximum unification with this basic power unit.
Based on preliminary developments and desires to ensure maximum unification with the base engine "3m3-406.10", the diameter of the cylinder was reduced to 86 mm. This was reached by installing a dry thin-walled sleeve into a cast iron monoblock; With the preservation of the size of the indigenous and connecting rod bearings of the base engine and, consequently, to almost complete unification of the processing of the cylinder block and the crankshaft. From the very beginning, the use of turbocharging, with cooling air cooling, was envisaged in the new diesel.
The first sample of the future "3m3-514", under the name "3m3-406.10", was made in November 1995. In the Yaroslavl plant of diesel equipment (Yazda), according to the technical requirements of the Savolzhsky motor plant, developed and manufactured a small-sized, multi-fuel fuel injector. The GBC eventually decided was not made of cast iron, but from aluminum.
In December 1999, the first pilot industrial batch of diesel engines "3m3-514" - 10 units was manufactured. In 2002, they debuted on "Gazelles". However, during the first two children, even the first year of exploitation, it turned out that there are difficulties with the maintenance of these engines, and their reliability could not withstand any criticism.
According to experts, the Archaic Production Equipment of the Volzhsky Motor did not have enough opportunities to ensure the necessary quality of metal and compliance with the accuracy of car processing. The diesel engine, in contrast to the gasoline, did not suffer. In addition, suppliers of components made their "spoon of conception" into the growth of non-thendation flow. And then the unstable quality sharply scared the buyers, at the beginning of a modern economy turbodiesel, who had merged into the idea of \u200b\u200breplacing the carburetor engines. As a result, by the beginning of 2004, the mass production of diesel engines on 3m3 was cooler, in fact and without starting.
Nevertheless, the refinement and adjustment "3m3-514" continued. Changed the design of the head and block, with an increase in their rigidity. For a better compaction of the gas joint, instead of the domestic flexible gasket, the GBC applied imported multilayer, metallic. The refinement and manufacture of pistons were assigned to the German company "Mahle". Changed, in order to increase the reliability and resource, were connecting rods, timing chains and a number of small details.
The result of this was the launch of the "3m3-514Z" modification of the modification "3m3-514z", and from 2006. UAZ HUNTER began with these motors. In 2007, 3m3-514z was PDogan and for installation on the classic cargo family of Ulyanovsk "Babe,". Soon appeared "3m3-514z" with the TNVD of the company "Bosch", which was discussed above, and then - and with Common Rail. These versions consumed up to 10% less diesel fuel and demonstrated the best engine richness at low revs. However, they did not get much spread.
A 4-stroke diesel engine has a row L-shaped cylinder and pistons, rotating one common crankshaft, and the upper arrangement of 2 camshafts. The motor is equipped with a liquid cooling system of a closed type, with forced circulation. The lubrication system is combined - under pressure and splashing. The updated Motor "3m3-514z2" has four valves on each cylinder, and the cooling of air entering the cylinder performs the intercooler, (its use has made it possible to increase the power of the power unit and improve its operation at low revs. The turbine used although not deprived of the characteristic effect "Turbo-pits", but it is distinguished by reliability and does not require maintenance and repair.

Despite the fact that Ulyanovsk all-wheel drives with diesel engines showed themselves noticeably better in terms of driving characteristics than gasoline, overpay for this 100 with little thousands of people who wanted extremely few. In addition, motors of the 3m3-514 family have a bad reputation in terms of reliability and durability of work. This led to the collapse of Sollers (which belongs to the ZMZ, and UAZ) project under the conditional name "Diesel UAZ".
The ZMZ-514 engine and its modifications are designed for installation on passenger and cargo-passenger cars UAZ Patriot, Hunter, Pickup and Cargo. The Bosch Common Rail Rail fuel system was used, a cooled exhaust gas recycling system with throttle pipe, which is also used for soft juggling. To drive the TNVD, the water pump and the generator uses a polyclinic belt with an automatic tension mechanism.

Engine problems
Early versions of the ZMZ-514 engine suffered from factory miscalculations that "got out" during operation. The members of the forum collected and classified refusals of the Diesel engine ZMZ-514: 1. Fragment of the GBC. It was celebrated on the engines until 2008 release. Signs: Care of coolant in the engine crankcase, gases breakthrough, emulsion on the oven probe. Cause of casting defect, enhancing the cooling system, broaching technology. From 2008, the defect has not been established on the CBC since 2008. Repair: Replacing the GBC to modern casting. Prevention for GBC from "Risk Zones": 1) Changing compensation Co. on the system with valves in the plug of the expansion tank with the rise above the level of the radiator. 2) Select engine operation modes without long loads over 3000 rpm. (If it seems small to whom it seems small, then for example, on rubber 245/75 on 5 daimos transmission at a speed of 110 km / h, revolutions 2900). 3) Checking the GBC broach on motors of 7-8 years of release. Links: a secret letter with ZMZ on a hundred expansion tank, alteration 2. Croskok / Options of the timing chain. Possible on all motors. Signs: Sharp engine stop. The engine does not start. Mismatching timing timing. Cause: Outdated hydraulic machine design does not ensure reliability. Embossed part of third-party manufacturer. Repair: Replacing broken valve drive levers. Adjusting timing marks. In the event of a break of the chain, defecting and replacement of the resulting drive parts. Prevention: 1) Monitoring the condition of the tension of the chain through the oil refining neck. 2) Replacing hydraulicers on the design of ensuring reliability. References: About Hydraulic Hydrauls Replacement Hydrauls on Euro4 Motor: The design has not changed. 3. The failure of the oil pump drive. It is characteristic of Euro3 engines with a vacuum pump on the engine block. Since the end of 10 years has not been noted. Signs: Oil pressure drop to 0. Cause: Not high-quality mothers gear. Improving the load on the drive due to the subdining of the vacuum pump. Repair: Replacing the gear of the oil pump drive from the audit of the oil pump and the vacuum pump. In the case of engine operation without oil pressure, detailed defects and, if necessary, more complex repairs. Prevention: Oil pressure control. Checking the supply oil hose to the vacuum pump in the absence of beggars. Checking the vacuum pump on the subflinking. If necessary, eliminating the defects found. On Euro4 motors: a vacuum pump of the altered design is located on the front cover of the GBC. The drive of the vacuum pump is directly from the upper chain. There is no constructively additional load on the oil pump drive. 4. Figure Plate Valve Srog into the engine cylinder. Signs: Smoking black smoke, hit / strikes in the area of \u200b\u200bthe engine, Trojection, impact. Cause: Non-high-quality part of the third-party manufacturer, burned out the valve plate brand from the rod, the passage of the inlet tube into the engine cylinder. Repair: Replacing the details of the details, depending on the degree of damage: piston, valve, cylinder head. Prevention: Turning off the valve wing with the silence of the system. On Euro4 Motors: Valve Logging Germany with electronic position control with a resource installed before replacement of 80,000 miles of run. 5. Reflection of the plug of a square. Signs: Reduced oil pressure, depending on the breakfast situation. Cause: not completed or not qualitatively completed plugs quarter. Repair: installation and connotation of plugs, depending on the consequences, repair or replacement of the engine block. Prevention: Control over oil pressure. Removing the engine of the engine with the status control of the plugs, if necessary, broach and coution. On Euro4 engines: about changing the quality control on the Connel for the better is unknown. 6.1 Crossing the drive belt TNVD. Print: reduction of thrust smoking, up to joy and noness. Reason: Dirt entering kV pulley, loosening belt tension. Repair: Standing belt. Prevention: Compliance with the rules for controlling the belt tension and replacement requirements. On Euro4 Motors: TNLD drive with automatic tensioner. 6.2 Side wear belt drive TNVD, belt break with limit wear. Marked on Motors Euro2. Signs: The desire to slip the belt from pulley TNVD, wear the sidewall with a tensioner roller, hiding belt for the housing. In case of breakdown, spontaneous engine jumper. Cause: Round tilt due to unreliable design and development on the axis of the roller mounting axis. Repair: Replacing the belt and stretch roller, turning the axis of the roller. Replacing the roller on the corrected design. Prevention: with the regulation of the roller replacement on the corrected design. On Euro3 Motors: Tensioner Roller Modified Design with Eccentric Tension. EURO4 MOTORS: Polycline drive belt with automatic tensioner. 7. Cutting the high pressure pipeline from the pump to the nozzle. It was noted on the Euro2 engines 2006 partially 2007 GW. Most often on 4 cylinders. Sign: sudden engine trimming, smell of diesel fuel. Cause: Incorrect selection of trigger bend angles when designing non-compensating loads. Incorrect installation in the tension. Solution: Replacing tubes on a new sample from 2007. Prevention for old tubes (does not hurt and new): When removing the installation of the tubes, do not allow tightening into the tension. First we press the tube to the saddle saddle, then screw the nut and stretch. Do not allow the touch of pipelines to each other. Correctly select the central position of the pump before assessing and adjusting the injection. Fuel from the right fuel tank 12 through a coarse filter of fuel purification 11 is supplied with fuel electric pump 10 under pressure to the foam filter 8 (ftot). At the pressure of the fuel supplied by the electric pump, more than 60-80 kPa (0.6-0.8 kgf / cm2) of the bypass valve 17 opens, removing excess fuel into the plum line 16. The purified fuel from the FTOT enters the high pressure fuel pump (TNVD) 5. Further, the fuel is supplied using a pump distributor of the TNVD in accordance with the order of operation of cylinders on high-pressure fuel supplies 3 to nozzles 2, with which fuel injection into the combustion chamber of the diesel engine. Excess fuel, as well as the air inserted into the system is removed from the nozzles, the pump and the bypass valve on fuel drain fuel supplies in the tanks

An important feature of the filter is also the detention and separation of water contained in the fuel. Moisture falling into the inner space of the TNVD may lead to the conclusion of the latter due to the formation of corrosion and wear of the plunger pair. The filter detained water is collected in the filter sump, where should be periodically removed through a drain plug. Drains of sludge from the ftot every 5,000 km of car run. Bypass valve Ball-type will be screwed into the fitting, which is installed on the filter of fine fuel purification. The bypass valve is designed to connect the excess fuel supplied by the fuel pump in the fuel drain line in the tanks. Engine design ZMZ-514

The engine has two camshafts: to drive intake and exhaust valves. File shafts are different, asymmetrical relative to the fist axis. In the rear ends, switchgears have labeling markings: intake - "VP", graduation - "Ime". Each shaft has five supporting necks. The shafts rotate in the supports located in the aluminum head of cylinders and covered with covers, broken 22 together with the head. For this reason, the covers of the distribution shafts are not interchangeable. From axial movements, each camshaft is held by a stubborn hemisphere, which is installed in the module of the front support cover and the protruding part enters the protrusion on the first support neck of the camshaft. At the front end of the camshafts there is a conical surface under the drive asterisk. To accurately set the phases of gas distribution in the first neck of each camshaft, a technological hole was made with a precisely specified angular location relative to the cam profile. When assembling camshaft drive, their exact position is provided by retainers, which are installed through the holes in the front cover into the technological holes on the first cervixes of the camshaft. The technological holes are also used to control the angular arrangement of cam (gas distribution phases) during the operation of the engine.
