Specifications ACEA. Classification of motor oils by ACEA What does A3 B4 mean

Acea. - Association created by the largest European manufacturers (Alfa Romeo, BMW, Citroen, Peugeot, Fiat, Renault, Volkswagen, Daimler Benz, British Leyland, DAF).
It was founded as a result of the CCMC merge with ATIEL. CCMC specification, which is currently replaced by ACEA, classify products like G for gasoline, PD for lungs and D for heavy diesel engines.
ACEA Specifications were designed to improve quality, performance and better attitude towards the surrounding environment.
Accepting aCEA specifications implies:

• Introduction to the operation of new innovation materials, in comparison with the currently used
• Analysis and certification of quality levels of each used formula
• The obligation of manufacturers does not make changes to the approved formulas
• ISO 9001/2 Factory Certification
• Consent of manufacturers with ATIEL standards, organization, together with CCMC identifying methods and parameters of the basis of ACEA certificates

Tests required by ACEA specifications are added to the CCMC formulated and make them more stringent.

The following letters classly class types:
[A] - gasoline engines
[B] - Light diesel engines
[C] - Fangs with devices to reduce the number of exhaust
[E] - Heavy diesel engines
Digital categories indicate various methods Applications associated with a certain class of engines specified by letters. The latest update of the ACEA specifications occurred in February 2002.
Responsibility for choosing the desired ACEA category lies on the engine manufacturer.
Oils addressed to a specific category can also comply with the requirements of another, but the oil of a certain category and class should be poured into specific engines.
The reference for the year is only for industrial necessities, giving information about the level and quality of the materials used. More than fresh editions of the specifications mean that new tests were conducted or new requirements were introduced into the category. At the same time, the editors retain backward compatibility, new will always fully maintain the level of old, except when a new category is introduced.

This is the Association of European Car Manufacturers. This organization was created to lobby the interests of automakers. One of the activities of ACEA was the issuance of requirements for the use of motor oils in engines of companies in this organization of companies.
To date, its membership is very impressive: BMW, Daf, Daimler-Crysler, Fiat, Ford, GM-Europe, Jaguar Land Rover., Man, Porshe, Psa Peugeot Citroen, Renault, Saab-Scania, Toyota, Volkswagen, Volvo.

The latest edition of the classification of motor aCEA oils Adopted in 2004. From this year motor oils for diesel and gasoline engines passenger cars ASEA is combined into one category. But, due to the fact that not all the newest cars that are classified by new edition ASEA, can be used in engines of earlier releases, manufacturers of automobiles still write on the packages of motor oil assigned earlier grades of quality according to the previous revision of 2002.

Please note that any machine manufacturer that uses in its advertising and on packaging ACEA standards should be in obligatory Conduct the necessary tests according to the requirements of the organization responsible for matching the quality of motor oils ACEA standards.

What do the numbers and letters in the class ASA?

In the latest edition of ACEA (2004), the car is divided into three categories:

A / B. - Motor oils for gasoline and diesel engines. This category included all previously designed classes A and B (until 2004 a - auto-oil for gasoline engines, in - for diesel). To date, there are four classes in this category: A1 / B1-04, A3 / B3-04, A3 / B4-04, A5 / B5-04.

FROM - New Class - Automasla for diesel and gasoline engines that meet the latest tightened requirements for ecology exhaust gases EURO-4 (as amended 2005). These engine oil are compatible with catalysts and diesel filters. Actually, it is an innovation in European environmental requirements and caused reconstruction aCEA classification. To date, there are three classes in this new category: C1-04, C2-04, C3-04.

E. - Motor oils for loaded diesel engines of heavy vehicles. This category existed from the very introduction of a classification (since 1995). In 2004, cosmetic changes were made, 2 new E6 and E7 classes were added, and two other, obsolete class were excluded.

Description of classes and categories

The classification of ACEA oils takes into account the design features and modes of operation of European engines. The presence on the canister of such marking indicates that the manufacturer of the engine mixture conducted a series of tests and its products corresponds to the quality of the liquids via ACEA.

How to choose motor oil, given the classification?

Association of European Car Manufacturers (ACEA), which places more stringent requirements for motor mixtures than the API, because European power units differ from American motors. They possess the following advantages:

• can develop a larger number of revolutions per minute;
• little motor weight;
• have a greater specific power;
• develop a greater speed;
• maintain more extreme temperature conditions of work.

According to ACEA, fluid is divided into classes:

• A - for gasoline engines;
• B - applicable to passenger cars;
• C - for motors operating on gasoline or diesel, equipped with exhaust gas neutralizers;
• E - designed for diesel cargo cars.

In this marking, there are Arabic figures, they mean the category on the operating characteristics:

• 1 - energy-saving mixtures;
• 2 - wide use liquids;
• 3 - mixtures with improved properties, are characterized by a large operational period;
• 4 - calculated for drives with direct injection;
• 5 - the mixtures in which improved additives are applied, possess best characteristicscharacterized by high fuel economy.

Table 3. Classification of motor mixtures for powerful diesel engines of trucks.

Output

Before applying the car, you must familiarize yourself with the requirements of the car dealer, since certain oils will not be able to provide the necessary thickness of the protective film on the parts of the motor - this leads to a decrease in the engine resource.

Taking advantage of the 2008 classification, you can choose motor fluidcorresponding constructive features Drive your car. If you are the owner of a not new car, then you need to use the inactive reduction of the 2004 classification system.

As follows from the name, the ACEA organization was created by major automotive concerns to coordinate the production and adoption of uniform product quality standards. Car enthusiasts are primarily interested in classification of ASEA oils - as a rule, the corresponding digital-letter codes are written on the CO's canices and help the buyer to choose the desired product.

About standard

Initially, a similar association was formed in the United States (API), but the difference in the design details of cars pushed the Europeans to the base of ASEA. In 1996, the first classification of ASE engine oils was determined, in which individual sections were devoted to lubricant materials for gasoline machines and. Later, in 2008, hydrocarbons were launched, suitable for both categories of engines, and the documentation was edited. Now the product is marked: ASEA A1 / B1, ACEA A3 / B3, etc., characterizes the lubricant for a gasoline engine, "B" - for diesel.

What are the numbers and letters in the class of ASEA

Now let's talk about the meaning of digital-letter codes in the classification of ASE engine oil.

Classes

According to the composition and field of application, these petroleum products are divided into three classes: A / B, C and E.

1. The letters of a / in canister say that inside the lubricant, recommended for and slightly loaded diesel engines.
2. C - oils for diesel and gasoline injector enginesWith environmentally friendly properties and complementing various filters for neutralizing harmful substances when exhaust.
3. E is the category of oils intended for heavy vehicles with a diesel engine. In the last edition, the discharges are added E6 and E7.

Figures from 1 to 7, ascribed to the letters, refine the properties of the lubricant and its composition.

Documentation

In general, the ASEA documentation reminds Russian GOST and consists of the classification of motor oils, requirements for them, describing the tests carried out, as a result of which a particular product was released under the auspices of the community. Observice of ASA standards is monitored by the European Commission EelQMS. Each manufacturer seeking to obtain motor oil from the Association of European Auto-Engineers is obliged to conduct research in laboratories recommended by association and prove that its products meet all specifications.

Description of classes and categories

A1 / B1 - all-season oils with moderate viscosity for gasoline and diesel engine (in machines with small loading). Such a hydrocarbon can be changed for two years. However, it is not suitable for all engines, and not recommended to apply it in a hot climate, where the temperature approaches the indicator above +25.

A3 / B3 - also applies both to gasoline and to diesel engines (in light transport) with the only difference that in this case we are talking about engines with high power. This species Lubricants are all-season in moderate climate and for a long time does not require replacement.

ASEA A3 / B4 engine oil - almost the same look as A3 / B3, but designed for newer cars with injector system Fuel supply.

ASEA ASA A5 / B5 oil is a low-grade type for machines with an injection fuel supply system. Its lubricants can not be called all-season - they are or harsh climate, and some engines are contraindicated.

C1 is a category for gasoline and diesel injector DVS with a reduced content of phosphorus and sulfur salts. Focused on savings and decay to neutral substances when exhaust. It has low viscosity to approach powerful engines with small gaps between the details. Such petroleum product cannot be used if the machine is pretty outdated or previously worked on a more aggressive lubricant.

C2 - hydrocarbon with higher, in comparison with the previous category, phosphate and sulfate content. Also, lubricants are designed for economical injection engines with exhaust filtration system.

C3 - the same in composition, as well as C2, but a more viscous type of oil - for operation in the southern climate.

C4 - in turn it is similar in composition with C1, but has a greater viscosity.

E4 - oil intended exclusively for diesel engines of large trucks. It helps to neutralize the N2O, even if a special filter is not installed, prevents the formation of particulate sediments.

E6 - practically the same as E4, but for cars equipped with filtration system.

Motor ASEA E7 oil is an improved version of E4 for machines without filters. Cleans piston cylinders and turbochargers. Lubrication does not require.

Perhaps you also met oils with marks on the A1 / V1-04 or 96 canister. These additional numbers are sent to the editorial board of ASEA. That is, learn properties this product It is possible in the species ACEA classification for 2004 or 1996.

To properly choose a lubricant for your engine, oil tables on ASA are not enough: you need to carefully read specifications Machines, examine related documentation (tolerances of the American Oil Institute - API, SAE - classification by viscosity, etc.).
