Engine refueling jitter (the reason for engine jitter may be HS code utilization in digital trade documentsrefueling problems, please check in time) Engine jitter is one of the common problems in the automobile industry, which can lead to unstable vehicle operation and affect Driving safely. The reason for the engine shaking may be the refueling problem. At this time, it is necessary to check the refueling system of the car in time. First of all, let's understand the reason for the engine shaking. During normal operation, the engine needs to continuously supply a mixture of fuel and air to generate energy. When the proportion of fuel and air mixture is not appropriate, it will lead to incomplete combustion, resulting in jitter and vibration. In this case, the quality and performance of the refueling system may be one of the root causes of engine jitter.Regarding the refueling system of cars, it usually consists of the following parts: 1. Fuel tank: the place where the car stores fuel; 2. Oil pump: lift or press the fuel in the fuel tank to the fuel system of the engine; 3. Fuel filter: filter impurities and pollutants in fuel; 4. Fuel injector: spray fuel into the cylinder of the engine and mix it with air to burn. If any part of the refueling system does not work properly, it will affect the performance of the car, resulting in engine shaking. The following are some common refueling problems that may cause engine shaking: 1. Oil pump failure: When the oil pump cannot supply fuel to the engine, the engine will not work properly and will jitter. Two. Fuel filter blockage: If there are dirt particles and impurities in the fuel, they may block the fuel filter, resulting in insufficient fuel supply and affecting the performance of the engine.3. Injector failure: There may be gaps or obstacles in the injector, causing the fuel to be unable to spray out and affecting the operation of the engine. Four. Damage to the fuel supply pipeline: The fuel supply pipeline may be cracked or damaged, resulting in fuel leakage or insufficient supply, affecting the work of the engine. 5. Damage to the fuel pump filter: The fuel pump filter may be damaged by debris such as sand and stones in the fuel, resulting in oil blockage and affecting the work of the engine. The above refueling problems may cause engine shaking, which seriously affects driving safety. In order to avoid this situation, we need to pay attention to the following points: 1. Replace the fuel filter and fuel pump filter regularly to avoid the accumulation of impurities and dirt, and ensure the normal operation of the refueling system. Two. Regularly check the oil pump pipelines and connectors to ensure that the system is free of oil leakage and damage, and repair and maintain it in time.3. Carry out regular car maintenance, including engine washing, to clean the carbon impurities in the cylinder, ensure the smooth supply of fuel, and avoid engine shaking. Four. Select high-quality gasoline, so as to reduce the impact of sediment on the fuel system and ensure the normal operation of the engine. In a word, refueling problems may cause engine shaking, so we need to pay close attention to the maintenance and upkeep of the car refueling system. If your car has a shaking problem, please contact professional car maintenance personnel in time for troubleshooting and repair to ensure driving safety.
