This car won't catch fire. What is a rattle?

This situation may be due to the following reasons:

1, battery voltage is insufficient. When the battery power supply is insufficient, the engine cannot be driven to reach the starting speed, so the car cannot be started. However, the repeated attraction of the magnetic bag and the starting relay will produce a clicking sound, which is relatively small. It rings every time it starts.

2. Excessive carbon deposition in intake pipe, throttle valve and idle motor. , so that the mixture of the engine can not reach the required air-fuel ratio, resulting in the vehicle can not start and stop, the engine continues to try to start, resulting in a click sound.

3. The lack of fuel supply in the fuel system is basically the same as the excessive carbon deposition in the intake pipe, and the air-fuel ratio of the mixed gas required by the engine cannot be reached, resulting in abnormal sound when the engine is constantly trying to start.

4, ignition system failure, which will directly lead to the engine can not start, the engine has been trying to start, resulting in a beep.

Extended data:

Automobile ignition failure:

1. Ignition difficulty caused by car carbon deposit, accompanied by slight jitter when idling. Cleaning the throttle, cleaning the carbon deposit at the air inlet and cleaning the fuel injector can solve the problem.

2. The weak ignition energy of spark plug will lead to the decrease of ignition energy of spark plug, which will lead to fire in severe cases. Moreover, at present, the engines of many models are mostly in-cylinder direct injection, so the requirements for spark plugs are higher.

3. Insufficient low pressure in the fuel circuit and insufficient oil pressure in the low-pressure oil circuit directly lead to secondary ignition of the engine. The specific reason is that the first ignition failed because the low-pressure oil circuit is building oil pressure, and the second ignition can be carried out once. Specific inspection components: fuel pressure regulator, gasoline pump, gasoline filter element and pipeline.

4. The battery is dead. Battery failures are more common. When you can't get a taxi, the owner's first reaction is that the battery is dead. The solution is also very simple, just find a car or other batteries to get electricity.

5. The exhaust pipe is blocked. Exhaust pipe blockage rarely happens, but some cars are blocked because of three-way catalytic crushing or external force deforming the exhaust pipe.

6. The mixture is too thick or too thin. Many car repair masters know a secret: the car doesn't stop, and other parts are fine. At this time, the master will spray carburetor cleaner on the accelerator to make the car stop easily. This is usually caused by the mixture being too thin.

7. Engine timing is wrong. If the engine timing does not match, the engine will definitely not stop. Many automobile engines use timing belts, and some models of engines may skip teeth when replacing the generator belt, which may lead to non-stop.
