When the engine is running, various gases begin to accumulate in the car. These include vapors of water, gasoline, and oil. They put a lot of pressure on the parts of the vehicle, which negatively affects their functionality and condition, as well as pollute the atmosphere.
Therefore, modern manufacturers install special valves for ventilation of crankcase gases. The main element of such units are membranes for cars, which allow gases to move freely.
FEATURES OF THE OIL SEPARATOR AND CRANKCASE GAS VENTILATION VALVE
An oil separator is a device that separates engine oil from compressed gas. It is an element of the crankcase ventilation system. Membranes of KVKG and oil separators are no different from each other. They are made of wear-resistant materials or rubber.
The oil separator has a very simple working principle: inertial forces affect small gas elements and oil droplets. While the CVCG is a valve that is in the open position with the diaphragm down. When the engine is started, the air is discharged and the gas cannot escape. This leads to an increase in pressure. When its indicator reaches values identical to those of the throttle, excess gas is released through the open valve.
If the crankcase ventilation system works stably, the car accelerates well. But, when problems arise (rupture/deformation of the membrane), the car begins to lose consistency, oil and fuel are consumed incorrectly. In this case, you need to immediately buy a membrane repair kit for the car.
WHAT DOES IT "SAY" ABOUT HYDRAULIC DIAPHRAGM/OIL SEPARATOR PROBLEMS?
Like any other part, this consumable over time begins to lose its former functionality not only in budget, but also in expensive cars. It is impossible to completely protect the membrane from wear, even if you use the highest quality lubricant.
In any case, the moment comes when the following manifestations appear:
- sucking and whistling;
- excess pressure in the crankcase;
- excessive consumption of oil and fuel;
- engine malfunction.
If similar symptoms are observed, the problem should be solved immediately. Valves for cars can be purchased assembled. However, these parts are not cheap, especially if they are original. It will be much cheaper to buy a separate membrane. Of course, if only her is damaged.
CRANKCASE GAS VENTILATION VALVES EGR
They can have a different design, the appearance of which is influenced by the requirements for the environmental friendliness of exhaust gases, the generation of the system and the model of the car. Systematic operation of the engine leads to the formation of soot on the spare EGR elements, which is one of the most common causes of system failure.
Malfunctions can be manifested in different ways, so you should pay attention to the following signs:
- jerks appeared when accelerating and increasing speed;
- the car is idling, but oscillations are observed;
- the engine has lost initial power;
- the "Check Engine" emergency icon appeared on the instrument panel;
- the amount of nitrogen oxide in the exhaust gases increased;
- thick black smoke comes out of the exhaust pipe;
- fuel is consumed much faster.
Diesel units are more vulnerable to such breakdowns due to soot in the exhaust. Soot, first of all, damages the DHW valve, interfering with the tight closing of the part, which leads to its jamming. As a result, the operation of the engine, muffler and exhaust system is disrupted.
If you do not start the repair in time, the unit will start to lose its power and it will be difficult to start. Also, the elements of the oil separator are deformed due to soot and increased temperature and mechanical impact. Timely purchase of a membrane repair kit for the recirculation system will ensure the maintenance of the correct functionality of the engine and other automotive systems. You can replace the element yourself or use the services of service center specialists.
