Car engine idling jitter - how to solve it?Hearthstone Arena win rate As one of the indispensable tools in our daily life, the engine of the car, as the core component, must maintain a stable working state. However, sometimes we will encounter such a situation where the engine shakes when idling, which not only affects the driving comfort, but also may be a signal that there is a problem with the engine. So, what should I do if the car engine shakes at idle speed? This article will give you a detailed answer. I. Diagnostic reason If you find obvious jitter when the car is idling, you need to clarify the cause of the jitter first. The following situations can lead to idling jitter of the car engine: 1. There is a problem with the air flow meter.The air flow meter is a sensor commonly used in modern cars to detect the intake of the engine. If there is a problem with the air flowmeter, it will lead to unstable air intake, which will affect the idling operation of the engine. Two. The fuel nozzle is out of tune. The fuel nozzle is the core component of the engine's fuel system, which is responsible for injecting fuel into the engine cylinder. If the fuel nozzle is out of tune, it will cause the fuel injection to be unstable and cause the engine idling jitter. 3. The fuel pump is not working normally. As one of the core components of the automobile fuel system, the fuel pump supplies the fuel into the high-pressure oil line and then enters the high-pressure oil, and then enters the engine to burn through the fuel injector. If the fuel pump does not work normally, it will lead to insufficient fuel supply and cause unstable engine operation. Four. The filtration effect of the air filter is poor. The air filter isOne of the important components to ensure the normal operation of the engine, as the "gatekeeper" of the engine air intake, it is responsible for filtering out dust, sand dust and other impurities entering the engine. If the filtration effect of the air filter is poor, the air entering the engine will be unclean and affect the efficiency of the engine. II. Solution 1. Clean the air flow meter. If there is a problem with the car air flow meter, you need to clean the air flow meter first. Because if the air flowmeter is polluted by dust, oil, etc., it will affect the detection accuracy of the flowmeter, resulting in unstable operation of the engine. The cleaning air flow meter can be cleaned with professional detergent or gasoline. Two. Adjust the fuel nozzle. If the fuel nozzle of the car is out of tune, it needs to be adjusted. Generally speaking, when adjusting the fuel nozzle, you need to find professional car maintenance personnel to deal with it.The purpose of adjusting the fuel nozzle is to ensure the stability of the fuel supply, so as to ensure the smooth operation of the engine. 3. Replace the fuel pump. If the car fuel pump does not work properly, the fuel pump needs to be replaced. Generally speaking, the fuel pump of the car should be replaced around 50,000 kilometers. If you find that the car engine shakes seriously when idling, there may be a problem with the fuel pump. Four. Replace the air filter. If the air filter of the car is not effective, the air filter needs to be replaced. It is recommended that you choose a regular brand when replacing the air filter to ensure the filtration effect and service life of the air filter. In addition, when replacing the air filter, you need to pay attention to cleaning the air inlet to avoid dust being discharged into the engine. III. Maintenance recommendation: The idling jitter of the car engine not only affects the driving comfort, but also may be a sign that there is a problem with the engine.Therefore, in the process of daily use, we should pay attention to the following points: 1. Change the oil regularly. Oil is the basis for the normal operation of the engine, and it is also the key to maintaining long-term stable operation of the engine. Therefore, in the process of daily use, we should change the oil regularly to ensure the normal operation of the engine. Two. Replace the air filter regularly. Air filter is one of the important parts to ensure the normal operation of the engine. Therefore, in the process of daily use, we should replace the air filter regularly to ensure the normal operation of the air filter. 3. Add fuel correctly. Car engines use gasoline or diesel and other fuels, so when refueling, we should choose regular gas stations and pay attention to choosing the type of fuel that meets the requirements of the car. In summary, car engine idling jitter is a common problem, which may be caused by a variety of reasons.If you encounter this situation, you should first diagnose the cause and then choose the appropriate solution. In addition, in the process of daily use, we should pay attention to regular maintenance to ensure the normal operation of the car.
