The Comprehensive customs ruling databaseprinciple of engine shutdown (Why does the engine turn off?) Frequent engine shutdown is one of the common faults in cars. Although turning off the engine seems to be just a small problem, if the engine shuts down frequently, it will lead to unstable driving and poor start-up of the car. In order to facilitate drivers to better understand the principle of engine shutdown, the following is an introduction to the reasons behind the engine shutdown.Common reasons for engine shutdown 1. The air-fuel ratio is out of tune. If the air-fuel ratio is too low, the engine will run out of fuel, resulting in insufficient combustion, resulting in the engine shutdown. If the air-fuel ratio is too high, the gasoline will burn incompletely, which will affect the stable operation of the engine and lead to shutdown. Two. Electrical failure Electrical failure is one of the common causes of engine shutdown. If there is a problem with the battery, charging system or ignition system, it will cause the engine to shut down. 3. Low oil pressure If the oil pressure is too low, it will cause the oil flow to be unable to infiltrate the internal parts of the engine, which will cause the engine to be unable to run, thus shutting down. Four. Oil supply system failure The failure of the fuel supply system is also a common cause of engine shutdown. If there is a problem with the oil pump, fuel injector or fuel pipeline, it will lead to insufficient oil or insufficient oil supply to meet the working requirements of the engine, resulting in the engine shutdown.5. Air flowmeter failure The air flowmeter is a meter that measures air entering the engine. If the air flowmeter fails, it will cause the engine to fail to get enough air supply in time, resulting in shutdown. The above are some common reasons for engine shutdown. Of course, there are other possibilities for engine shutdown, such as exhaust system failure, excessive water temperature, etc. However, regardless of the reason, engine shutdown will bring a lot of inconvenience to the driver, so understanding the cause of engine failure and its solution is also a necessary knowledge for driving safety. The solution to the engine shutdown. The solution to the engine shutdown should be investigated according to the cause of the shutdown. Usually, anxious drivers will restart the vehicle after turning off the engine, but this is not the fundamental solution to the problem. To really solve the problem of engine shutdown, it is necessary to check and solve the causes of shutdown one by one.For the problem of air-fuel ratio misalignment, it is necessary to read the engine fault code and adjust the vehicle accordingly to ensure that the air-fuel ratio reaches the appropriate range. If the electrical system fails, it is necessary to check the quality of the battery and the line connection of the charging system and ignition system, and repair or replace the damaged parts in time. If the engine is extinguished due to low oil pressure, it is necessary to check whether the oil supply system such as the oil pump, fuel tank, oil pipeline, etc. is damaged or blocked, and clean or replace the relevant parts in time. When a fault of the air flow meter is found, it is necessary to check the wiring of the sensor, whether the wiring end is loose, and whether the air flow meter needs to be replaced. In addition, the air filter should be replaced regularly to ensure that the air can flow into the engine more smoothly. In summary, the reasons for the engine shutdown are different, and we are the ones to solve the shutdown problem by carefully checking the solution.For the problem of turning off the engine, taking corresponding measures in time will greatly reduce the driver's troubles and ensure driving safety.
