There is jitter when the cold car starts. What's wrong with the car?

Tip: There is shaking when the cold car startsIt may be due to the production of gasoline glue due to poor gasoline. It is recommended to clean the oil route or add gasoline cleaner for a long time.

What to do with the car's cold start jitter? The first problem faced when the ignition energy is low. The car is cold start is the low temperature. The temperature in the engine is not enough, and the temperature of the fuel and lubricating oil is not enough, so more oil should be injected during cold start to meet the dynamic requirements. The larger the gap of the spark plug, the smaller the ignition energy.

The engine has serious carbon accumulation. The most common reason is excessive carbon accumulation in the throttle valve or fuel injector. When there is too much carbon inside the engine, the gasoline sprayed by the fuel injector during cold start will be absorbed by carbon accumulation, resulting in excessive mixing gas, making it difficult to start. It is easy to start only when the carbon-absorbed gasoline is saturated.

Hello, it's my pleasure to answer your question.Check whether the idle motor and throttle valve are normal, whether the fuel injector is leaking, and whether the gasoline pump is depressurized.

There will be some shaking at this time, which is normal and there is no need to worry too much. Nowadays, many engines adopt in-cylinder direct injection technology, so in-cylinder direct injection engines are more likely to accumulate carbon. It is recommended that car owners use a cylinder-driven jet engine to clean the carbon inventory every 20,000 kilometers.

What is the reason for the start-up jitter of the cold car

1. Tip: The jitter in the cold start-up of the cold car may be due to the production of gasoline glue due to poor gasoline. It is recommended to clean the oil line or add gasoline cleaner for a long time.

2. The steering pump drives the belt to slip. The steering pump is driven by Pima Na Jean, stuffyIf the friction between the belt and the pulley is too small, the belt will slip on the pulley and make a squeaky sound at this time.

3. The following are the main reasons for the start-up jitter of the vehicle: the low temperature and the low temperature of the exhaust pipe will also be reduced accordingly. The oxygen sensor also has the lowest working temperature. The vehicle ECU cannot obtain accurate data, resulting in errors in the ignition and oil-gas mixing control, resulting in the weakening of the vehicle's power output and jitter.

4. Cold start jitter First of all, start from the cold start. The main reason for the cold start body shake is insufficient fuel combustion, resulting in insufficient power of the car. The ignition energy is low. When starting, especially when the temperature of fuel and lubricating oil is low, more oil is needed to meet the power.

5. The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

6. First of all, this situation is the low temperature, and the temperature in the engine is not enough, so more oil should be injected during cold start to meet the requirements of power. The larger the gap of the spark plug, the smaller the ignition energy.

What are the causes and solutions of cold car start-up jitter

Tip: The shaking of cold car start-up may be due to the production of gasoline glue due to poor gasoline. It is recommended to clean the oil line or add gasoline cleaner for a long time. .

The specific reason for the start-up jitter of the cold car is: in this case, first of all, the temperature is low, and the temperature in the engine is not enough, so more oil should be injected during the cold start to meet the requirements of power. The larger the gap of the spark plug, the smaller the ignition energy.

The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

The engine has serious carbon accumulation. The most common cause of car shaking is too dirty throttle or too much carbon in the fuel injector. When there is too much carbon inside the engine, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon, resulting in the cold start mixture being too thin and difficult to start.

The most common is that the throttle valve is dirty or the throttle valve fails, which will lead to idle shaking. The main reason why the throttle valve is dirty is that there is carbon accumulation at the junction of the shaft of the throttle valve plate and the throttle body, resulting in the opening of the throttle valve not being accurate enough, so the idling will shake.

Most of the starting shaking of a car is related to the clutch. The specific reasons are: when the car is used for too long, the elasticity of the clutch pressing spring weakens, and the diaphragm spring cracks, etc. will cause shaking when the clutch is connected. The strategy that should be adopted at this time is to replace the spring.

What's the matter with the shaking of the cold car?

Most of the cold start jitter is caused by poor combustion of fuel. The fuel tank has too much glue moisture, and the cold start is not brought to the combustion chamber, and then mixed with the fuel tank is beaten into the combustion chamber. The jitter caused by poor combustion.

Tip: The shaking of the cold car start may be due to the production of gasoline glue due to poor gasoline. It is recommended to clean the oil line or add gasoline cleaner for a long time.

I: There are several main reasons for the start-up jitter of cold cars: carbon accumulation, weak ignition, low cylinder pressure, unqualified fuel, etc. The more detailed reasons are as follows: 1: Too much carbon accumulation in the throttle valve, fuel injector and intake duct may be one of them, or it may be all of them.

It causes the car to shake. Car carbon accumulation: Car carbon accumulation is one of the important reasons for the cold start jitter of the car. In the daily driving process, due to the different driving environment and the driving habits of the driver, it will lead to different degrees of carbon accumulation. Excessive carbon accumulation in the valve and intake pipe makes it difficult to start the cold car.

What's wrong with the engine shaking after a while

Seven reasons and solutions for a cold car starting and shaking will be normal after a period of time; the spark plug gap is large, the ignition energy is insufficient, the ignition fails, and it cannot be started, So that it shakes. Solution: Check the spark plug carbon, clean or replace the spark plug. The concentration of the mixture is too thin or too thick, which may be a failure of closed-loop control.

[Pacific Automobile Network] The reason why the cold start shakes for a while is that there is too much carbon accumulation inside the engine, and the gasoline sprayed by the cold start fuel injection head will be absorbed by a large amount of carbon accumulation, resulting in the cold start mixing gas being too thin, causing the start to shake. Because the carbon accumulation can absorb an appropriate amount of fuel, the ECU judgment An error occurred.

The engine has serious carbon accumulation. The most common cause of car shaking is too dirty throttle or too much carbon in the fuel injector. When there is too much carbon inside the engine, the gasoline sprayed by the cold start fuel injector will be absorbed by a large amount of carbon, resulting in the cold start mixture being too thin and difficult to start.

Too much carbon accumulation of throttle valves, fuel injectors and intake duct may be one of them, or it may be all. When there is too much carbon inside the engine, the gasoline sprayed by the cold start fuel injection head will be absorbed by a large amount of carbon accumulation, resulting in the cold start mixing gas being too thin, causing the start to shake.

There are many reasons for the car's cold start-up shaking car: the spark plug is in poor condition. The high-voltage line was pierced and jumped into the fire. Poor contact with the distributor. The fuel injector is blocked, and the fuel atomization is not good. There is carbon accumulation in the combustion chamber, resulting in valve jamming.The low temperature causes the oil to condense, the fluidity becomes low and the lubrication is poor, and the shaking phenomenon disappears when the temperature rises.

What is the reason for the engine shaking of the cold car?

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

Causes for the shaking of the cold car engine: The most common reason for the shaking of the car is that the throttle valve is too dirty or the fuel injector has too much carbon.

Tip: The shaking of the cold car start may be due to the production of gasoline glue due to poor gasoline. It is recommended to clean the oil line or add gasoline cleaner for a long time.

The possible reason is that the belt adjustment is too loose, the pulley groove is sensitive and excessive wear, or the new belt and the old pulley do not match well.You can use a simple method to judge. When there is a sound, pour a little water on the belt. If the noise disappears, it means that the belt has slipped.

It causes the car to shake. Car carbon accumulation: Car carbon accumulation is one of the important reasons for the cold start jitter of the car. In the daily driving process, due to the different driving environment and the driving habits of the driver, it will lead to different degrees of carbon accumulation. Excessive carbon accumulation in the valve and intake pipe makes it difficult to start the cold car.
