The mixed gas is too thick: When the engine mixed gas is too thick, the phenomenon is: it is difficult to accelerate after starting, and the engine runs unevenly; the exhaust pipe smokes black smoke, and the engine is accompanied by a strange sound; the engine power decreases and the fuel consumption increases.Most of these are related to carbon accumulation, filter blockage, etc., and generally do not need to be overhauled.
When the vehicle starts, the valve will lack the sealing and lubrication of the oil, resulting in a sizzling sound. This is a normal situation. Second, the abnormal sound made by the belt when starting. In this case, it is necessary to check whether there is a problem with the belt in time. If there is an abnormal sound of the belt, first check.
The engine temperature is too low: When the car is cold started, the engine temperature is too low to work normally. At this time, it is normal to have some abnormal sounds. This situation is normal. Just wait for a while and wait for the engine temperature to rise to the normal level.
The abnormal noise during the cold start of the engine may be caused by engine oil dirt, improper oil viscosity, excessive engine carbon accumulation, carbon tank solenoid valve failure, secondary injection system failure, electric vacuum air pump, etc.
1. The engine claw pad is aging. The claw pad plays the role of supporting the engine. After aging, it will make a strange sound when the car starts.
2. There are many reasons for the abnormal sound when starting the car.Including low engine temperature, thermal expansion of automobile ternary catalyst, gearbox failure, engine belt or chain wear, etc.
3. There are many reasons for abnormal noise when the car starts, including low engine temperature, thermal expansion of the car's ternary catalyst, gearbox failure, engine belt or chain wear, etc. The engine temperature is too low: When the car is cold started, the engine temperature is too low to work normally. At this time, it is normal to have some abnormal noise.
4. The reasons for the abnormal sound of the car starting and the solution are as follows: there is a sharp chirping sound at the moment the car starts.
5. Once the fuel of the car is insufficient, the engine will make a rattling sound when it is ignited, but it will also occur that it cannot start normally. It must be checked.Whether the fuel is sufficient or not, this problem is very easy to solve. You only need to add fuel in time.
1. Try to check the coolant, the oil pressure is too high or too low, check the oil pressure gauge, and there may be a problem with the ignition time setting, which will also lead to such symptoms. As for others, it may be an internal problem with the engine, such as EGR valve blockage.
2. Caused by engine carbon accumulation, because the old engine oil is getting thinner and thinner, more and more carbon accumulates. When the oil is thin, it is easy to spee the oil, resulting in more and more carbon accumulation and loss of a lot of power. When replacing with new oil, the engine cannot adapt to the viscosity of the oil, which may increase the speed, resulting in loud engine noise.
3. The engine foot mat is aging, resulting in the inability to reduce the vibration. The engine and the frame are softly connected, and the foot mat is separated from the engine and the frame. Over time, the rubber rubber sleeve of the foot mat slowly ages and loses its original shock absorption effect, and the noise will naturally become louder. The design of the vehicle itself leads to loud noise.
