Automobile engine as an automobileCoinmasterfreespindailyThe source of power, its performance and life have always been the focus of car owners. However, in the process of daily use, car owners may encounter the phenomenon of engine deflation. So, what is engine deflation? What are the causes of it? How to diagnose and solve it? This article will give detailed answers to these questions.

1. What is engine blow

Engine gas channeling means that during the operation of the engine, due to the poor sealing between the piston ring and the cylinder wall, the mixed gas or exhaust gas in the cylinder enters the crankcase through the gap between the piston ring and the cylinder wall, resulting in the decrease of cylinder pressure and affecting engine performance.

Second, the cause of engine gas leakage.

There are a variety of reasons for engine deflation, including the following.Coinmasterfreespindaily:

The serial number reason 1 is that the piston ring is worn or damaged, which leads to the decrease of sealing property, the wear or uneven surface of the cylinder wall, the failure of the crankcase forced ventilation system (PCV), the excessive pressure in the crankcase and the poor sealing of the 4 valves, which leads to the gas entering the crankcase 5 engine to run at high temperature for a long time, resulting in a thermal expansion mismatch between the piston ring and the cylinder wall.

Third, the diagnosis method of engine gas leakage.

The diagnostic methods of engine gas leakage mainly include the following:

Serial number diagnosis method 1 check the crankcase forced ventilation system to ensure its normal operation 2 carry out compression test to check whether the cylinder pressure is normal 3 check the wear of cylinder wall and piston ring 4 check valve tightness

Fourth, the solution to the gas leakage of the engine

In view of the causes of engine gas leakage, the following solutions can be taken:

Serial number solution 1 replace worn or damaged piston rings 2 replace cylinder liners or perform cylinder hinge honing to restore tightness of cylinder walls 3 check and repair crankcase forced ventilation system to ensure its normal work 4 replace valve seals to improve valve tightness

Gas leakage of the engine will not only affect the dynamic performance of the vehicle, but also lead to the increase of fuel consumption and excessive emissions. Therefore, when the phenomenon of engine gas leakage occurs, the car owner should diagnose and repair it in time to ensure the normal operation of the car. At the same time, regular car maintenance and replacement of worn parts are also important measures to prevent engine gas channeling.
