1. Going to the corresponding repair shop for repair and oil replacement is the most common part of maintenance. Engine oil plays the role of lubricating, cooling, absorbing shock and reducing engine wear. , it must be replaced regularly. Different types of engine oil have different replacement intervals. There are now three types of motor oil: full synthetic motor oil, semi-synthetic motor oil, and mineral motor oil. Full synthetic motor oil has better high and low temperature types, and its price is also the highest of the three. The replacement cycle is usually 10,000 to 12,000 kilometers. The replacement interval for semi-synthetic engine oil is 8,000-10,000 kilometers. Mineral engine oil is usually replaced every 5,000 kilometers.
2. The engine has significant carb depositsone.
The most common cause of car vibration is that the throttle valve is too dirty or the fuel injection nozzle has too much carbon deposits. When there is too much carbon deposit inside the engine, the gasoline ejected from the cold start fuel injection head will be absorbed by the carbon deposit, making the cold start mixture too fluid, which will make it difficult to start. The only way is to wait until the gasoline is absorbed by the carbon deposits. When the car is saturated, it is easier to start the car. Once the car is started, gasoline adsorbed on carbon deposits will be sucked into the cylinder by engine vacuum. suction for combustion, which will also make the mixture richer. The engine's combustible mixture is sometimes thin and sometimes rich, resulting in vibration at idle.
3.. Ignition system problems
Check the connectionsoperating conditions of spark plugs, high voltage wires and ignition coils. Poor operating conditions of the ignition system and spark plugs can also be the cause. this type of failure.
4. The oil pressure is unstable
If you have cleaned the carbon deposits from the engine, washed the throttle, replaced the spark plug, etc., and still find that the body shakes when idling , it is recommended to check the fuel supply pressure and whether the manifold pressure sensor is normal. If the oil pump supply pressure is abnormal or the manifold pressure sensor has an incorrect value or malfunction, it will cause vibration in the vehicle body.
The engine still works.
Because after switching on, the generator will continuously output about 14 DC voltage, which can provide about 1000 watts of powerelectrical power. In addition to charging the battery, it is enough to provide electricity to the entire vehicle. .
So, once the gasoline car is turned on, remove the battery - the engine will still work normally.
But the voltage of the entire vehicle at this time is 14 volts. This voltage is limited by the voltage regulator inside the motor. Once the voltage regulator fails, the voltage will increase significantly, affecting operation. electrical devices throughout the vehicle are a test (and dangerous).
So, try not to remove the battery.
