The Jetta car hot car can t catch fire, and the Jetta hot car doesn t catch fire when it starts

lz Hello, to sum up, one. 1. It is very shaky after getting on the car in the morning, because the engine speed is too low and the car is shaking, it may be that the throttle is dirty and the throttle needs to be cleaned. 2. The engine shakes due to poor engine work, there may be impurities at the fuel injector that cause the injection amount to be inaccurate (you have ruled out this), and the metal additives in the fuel cause the formation of iron oxides and other metal oxides on the surface of the spark plug, which will affect the working conditions of the engine.

3. The carbon deposition of the fuel injector (which is also excluded) will cause the difference in the amount of fuel injected by the fuel injector of each cylinder, resulting in engine shaking or car; 4. When the spark plug has too much carbon deposit, (it is also excluded) causes the spark plug to leak and cannot work, and the engine shakes. 5. In addition, it is necessary to check whether the idle motor has too much carbon deposit, which causes this phenomenon.

Two. The hot car is turned off. (Of course, the hot car stalling also includes the first situation mentioned above), but the main reason for the hot car stalling I think is because of the problem of cooling, because the same cold car can but the hot car cannot.

Have the master check the coolant, as well as the oil, temperature sensor, and oil pressure sensor.

Hope it helps.

If the battery warning light is not lit, you can find a car to start to see if it can start, if it can start normally, the battery of the car is dead, you can charge it or replace it with a new battery. If it still can't start after taking the power, then you have to go to the garage to check whether the starting motor is faulty.

When the car is hot, the engine will not start. It could be that the battery is dead or internally damaged. The battery pile head is too dirty or the connector is loose, the additional relay contacts cannot be closed or ablated, the electromagnetic switch contacts are ablated, and the starter is faulty inside.

It can cause the starter to not work, or it could be a faulty dispenser gasoline pump or an ECU issue.

Feedback the problems that can be reflected to the relevant departments, wait patiently for the verification of the blindness, keep the mobile phone and other communication equipment unblocked, and facilitate the factory employees.

The reasons why it is difficult to start a hot car are as follows:1. Carbon build-up in the car makes ignition difficult, and there is slight shaking when idling. Cleaning the throttle, intake carbon deposits, and fuel nozzles can solve the problem.

2.The ignition energy of the spark plug is weak, and some car owners do not replace the spark plug after the end of the maintenance period in order to save money, which will lead to a fire when the ignition energy of the spark plug is seriously reduced. Moreover, most of the engines of many models are directly injected in the cylinder, so the requirements for spark plugs are relatively high.

3.The insufficient low pressure of the fuel circuit and the insufficient rolling pressure of the oil god of the low-pressure oil circuit directly lead to the secondary ignition of the engine. The specific reason is that the low-pressure oil circuit is building oil pressure for the first ignition, and the second time it can catch fire.

Specific inspection components: fuel pressure regulator, gasoline pump, gasoline filter, and internal piping.

Millions of car purchase subsidies.

Jetta hot car is not good and catches fire, which may be caused by excessive carbon deposition in parts such as throttle valves, idle motors, or air intakes. Because of the excessive carbon deposition and dirt in the intake tract, the cross-sectional area of the air passage changes, so that the control unit can not accurately control the idle air intake, resulting in the mixture being too thick or too thin, so that the combustion is abnormal or the engine shakes or even cannot start after starting.

Or there is a slight leakage of the fuel injector, which causes the fuel to leak into the combustion chamber for a period of time after the vehicle is turned off, resulting in the mixture being too thick when starting again, and finally making it difficult to start. It is also possible that it is caused by damage to the activated carbon canister. Because if the solenoid valve is always open, the mixture in the intake tract of the engine will always be in a thickened state, resulting in the phenomenon that the mixture is too thick when the car is hot, which is not easy to start.

It is recommended to conduct an on-site inspection based on the above analysis.

Jetta has taken the lead in applying the world's most advanced 5-valve multi-point electronic injection engine in China, and with its unique product design performance and all-round safety technology and equipment, it has formed a distinctive product personality of Jetta series cars. Jetta sedan not only created a precedent for the application of high-end engine technology and safety technology and equipment for mid-range family cars, but also took the lead in adopting advanced multi-point EFI technology for all products, and all installed three-way catalytic reaction old wild devices, which improved the environmental performance of mid-range cars, so that Jetta cars became the pioneer of environmental protection in mid-range cars.

Poor ignition of a Jetta hot car can be caused by excessive carbon build-up in the throttle, idle motor, or air intake. Due to excessive carbon accumulation and dirt at the air intake, the cross-sectional area of the air duct changes, so that the control unit can not accurately control the idle air intake, resulting in the mixture being too thick or too thin, burning abnormally, and the potato pie engine shaking or even unable to start after starting.

Or a slight leak in the injector can cause fuel to leak into the combustion chamber for a period of time after the vehicle has been turned off, which can lead to an overly thick mixture when restarting, and eventually difficult to start. There is also a chance that the activated carbon canister will be damaged. If the solenoid valve is always open, the mixture at the engine intake will remain thick, which will cause the mixture to be too thick to start when the engine is hot.

It is recommended to conduct an on-site inspection based on the above analysis.

Jet Liheda is the first to apply the world's most advanced 5-valve multi-point EFI engine in China, with its unique product design and performance and all-round safety technology equipment, forming a distinctive product personality of Jetta series sedans. Jetta not only pioneered the application of high-end engine technology and safety technology and equipment in mid-range family cars, but also took the lead in adopting advanced multi-point injection technology in all products, and all were equipped with three-way catalytic reactors, which improved the environmental performance of mid-range cars, so that Jetta cars became the environmental protection pioneer of mid-range cars.

Causes and solutions:

1. The battery loses power.

Performance characteristics: the starter starts to rotate but the speed is not enough, that is, it is weak, and then the starter only clicks and does not rotate. Low temperature in winter and forgetting to turn off individual electrical equipment will cause the vehicle to be unable to start, especially in winter for long-term short-distance low-speed use, the battery voltage will be lower than the rated value, starting and unable to operate normally.

Solution: If it happens, please call the service station to rescue**, or find the right car, or temporarily on fire, and then you must go to the service station to replenish the battery.

Performance characteristics: no oil pressure in the engine oil supply pipe. This situation usually occurs in the morning when the temperature is very low, and is caused by long-term dirt in the fuel line. When the temperature is very low, the water mixes with debris and the fuel line is blocked, and as a result, it cannot be started.

Solution: Put the car in a warm environment, and the car can start in a while; Or use the method of cleaning the oil circuit to solve it completely.
