How to turn off the engine (why does the engine suddenly turn off?USA customs data analysis services) Engine shutdown has always been a common problem in car driving, especially in low-speed driving and emergency stops. Therefore, for vehicle drivers, it is necessary to master some basic knowledge and skills to avoid safety accidents caused by engine shutdown.Why does the engine suddenly turn off? There are many reasons why the engine goes down. The more common reasons include the following: 1. Mechanical failure. During driving, all parts of the car engine are running at high speed, and excessive wear or damage of mechanical parts may also affect the operation of the engine, and even cause the engine to suddenly shut down. Two. Insufficient fuel supply or excess engine Insufficient fuel supply or excess may also cause the engine to shut down. When the engine is running, the oil pump will supply fuel to the fuel system, and there are various possible faults in the process. For example, oil pump failure or fuel pipeline blockage can lead to insufficient fuel supply; on the contrary, when there is too much oil pollution or organic pollutants in the fuel system, it may also lead to excess fuel, thus affecting the normal operation of the engine.3. Spark plug failure Spark plug is one of the key parts of engine ignition. If the spark plug fails, such as poor contact or excessive electrode spacing, it will affect the ignition of the fuel, resulting in the engine shutdown. Four. Electrical system failure The electrical control system of modern cars is very complex, containing a large number of sensors and computer control units. These control units will cooperate with each other to ensure the stable operation of the engine. Electrical system failure is one of the common causes of vehicle failure, such as insufficient battery power or charger failure, which can lead to engine failure. How to deal with engine shutdown In the event of engine shutdown, the following response methods should be adopted: 1. Check the fuel supply. Insufficient or excess fuel supply is one of the common causes of engine shutdown. If the vehicle turns off, you first need to check whether the fuel supply is normal.If you find problems such as fuel pipeline blockage or oil pump failure, you can first adopt simple cleaning methods, such as cleaning the fuel filter or replacing a new oil pump. Two. Check the electrical system. As mentioned above, electrical system failure is one of the common causes of vehicle failure. In this case, you need to check the battery power of the vehicle to make sure that it is fully charged or the charger is working properly. In addition, it is necessary to check whether the generator is working normally. The computer-controlled power tracking device of Hyundai Automobile will automatically detect the generator to ensure that it can supply stable power. 3. Replace the spark plug. If you find that the spark plug is faulty, you can replace the new spark plug. When replacing spark plugs, it is necessary to make sure that the installation is correct and replace the spark plugs regularly according to the frequency and mileage of the vehicle. Four. Check the mechanical parts. While the vehicle is driving, the damage or wear of the mechanical parts may also cause the engine to die.Severe wear can lead to sliding or crushing, which will affect and prevent the engine from running. If you suspect that the mechanical parts are faulty, you should find a professional vehicle maintenance agency for inspection or maintenance in time. In a word, in the process of driving the vehicle, if the vehicle turns off, measures should be taken according to the specific situation to repair or alleviate the engine failure. However, more attention needs to be paid to prevent problems that may cause engine shutdown as much as possible, such as regular maintenance of vehicles and timely replacement of damaged parts, so as to avoid the danger caused by engine failure to car driving.
