How to Solve the Idle Jitter in Yue Bin

The reason of Yue Bin idling jitter may be that the throttle valve is too dirty, and there is too much carbon deposited in the fuel injector and air intake. Clean the throttle, fuel injector and air inlet in time.

The causes of engine idling jitter are as follows: 1. Dirty air filter: The air filter is designed to protect the engine from wear and tear, and it is usually replaced around 65,438+00,000 kilometers. If it is not replaced in time, it will lead to insufficient air intake and engine idling jitter, which can only be solved by replacing the filter element. 2. High-voltage line disconnection: High-voltage line disconnection means that the conductor core of the high-voltage line is broken, which will affect the ignition and cause the engine to shake. You can use a multimeter to measure the resistance, and change it to a resistance that is obviously several times larger. 3. There is something wrong with the spark plug: the service life of the spark plug is long, and the ignition efficiency will obviously decrease after exceeding 30,000-40,000 kilometers, which will affect the ignition. This is the most common fault, so replace all spark plugs. 4. Abnormal water temperature: The working temperature of the engine is within the normal range. If the water temperature is high, the ignition time will be earlier, the oil-gas mixing ratio will change, the viscosity of oil will become thinner and the lubrication performance will become worse. Common causes of failure are: jitter caused by insufficient antifreeze, thermostat failure, fan failure, and inaccurate thermostat switch temperature, all of which can be eliminated.
