Engines Peugeot EW12A, EW12J4
Content
The engine is an integral part of any car. With its help, the movement of the vehicle is organized due to the timely supply of fuel and the adjustment of the required power. Few people know, but in addition to cars, Peugeot produces its own engines, and below we will talk about such ICE models as EW12A, EW12J4.
History of creation
First of all, consideration of engines must begin with the history of the creation of units. In this case, it is worth considering separately each of the presented models.
EW12J4
This engine is an advanced development of the PSA concern. For its time, the unit was considered quite modern. First appeared in 1999.
However, the disadvantages of the device are the high consumption of fuel and engine oil. Also, the manufacturers failed to make it silent, and this alarmed many car owners when they heard extraneous sounds during the operation of the vehicle.
The developers equipped the motor with anti-rotation balancing shafts, as well as a hydraulic drive, which made it possible to obtain an original design as a result. Additionally, a throttle valve was added to the device.
EW12A
The release of this model took place for the first time in 2005. At that time, it was also considered a fairly modern unit, and the company used it in many of its cars.
Description
The description of the engines implies a consideration of the design of the device, as well as the main features that each model has.
EW12A
The design of this engine is quite complex. At the same time, the unit is considered demanding on the quality and timing of oil changes. Manufacturers recommend using Total Quartz oil in an internal combustion engine, as it is considered to be quite reliable among existing ones.
Inside the EW12A there are cylinders equipped with valves, as well as an intake manifold made of plastic. It is worth noting that this element may fail during the reverse "pop" of gas on the car. Also, the engine is equipped with spark plugs and other elements that contribute to its efficient operation.
EW12J4
This model, as already noted, was released in 1999, and its production did not stop until 2009. The engine capacity is 2,2 liters, the designation of the unit is EW12J4, which refers it to the EW family. The design is also quite complex, but at the same time high-quality and durable.
Technical specifications
An experienced driver knows that when choosing a car, it is important to look at its technical characteristics. The study of the main parameters will help to draw a conclusion about the performance and reliability of the unit, as well as determine what power and speed the car can develop during operation.
Below is a table of technical characteristics of both models, since the design of the engines is almost identical.

What cars were they installed on?
Additionally, you can note the class of environmental friendliness and the approximate resource of the engine. In the first case, we are talking about the EURO ¾ class. As for the service life, the manufacturers guarantee the reliable operation of the unit over 275 thousand km. To see the engine number, lift the plastic cover up. Then on the left side you can see the aluminum pad, which is dot engraved (engine number).
Engines are created to organize the stable operation of the car. Each of these models was subsequently installed on a specific vehicle, and this issue is worth considering in more detail.
EW12A
The engine was used on a Peugeot 407.
EW12J4
This model has been in cars such as:
- PEUGEOT 406.
- CITROEN C8.
Fuel consumption
As for fuel consumption, on average, each of the models under consideration consumes about 12,5 liters of fuel in the case of city driving, 7,2 liters on the highway and 9,1 with a mixed type.
Disadvantages
PEUGEOT engines are considered quite reliable, and the main disadvantages that arise during the operation of the engines of the models in question are:
- Oil leakage from seals and valve covers.
- The occurrence of problems in the operation of the ignition system.
- Failure of various sensors.
- Depreciation of elements after 50 thousand and 100 thousand km.
Also, many owners note that during operation the engine is quite noisy, especially at idle.
At the same time, it should be noted that basically problems with the engine arise due to incorrect operation of the car. Regular technical inspection and timely repairs will help to avoid serious problems.
