What should I do if the engine fault light turns on and prompts that the engine mixture is too thick?

The opening position of the throttle valve is normal, there is no jam phenomenon, and the test is normal without an air filter. You can check whether the air filter element is blocked because it is too dirty, and the new filter element should be cleaned or replaced. Improper cleaning of the main measuring hole will cause the loss of the measuring hole and increase the flow rate. Remove the fuel injector and disintegrate for further inspection.

Oxygen sensor pairThe key to monitoring the state of the mixed gas is to judge the condition of the mixed gas by checking the oxygen content in the exhaust gas.

Hello. If the engine detection system is too thick, it means that the engine's air intake system is faulty or the fuel system is faulty. The prohibition system is mainly due to the fact that the air filter is too dirty, resulting in insufficient air intake, or the sensor fails. The main reason for the fuel system is the fuel injector. The poor work of spraying paint leads to more oil injection, which will lead to excessive mixing gas.

How to solve too thick mixed gas

When the mixed gas is too thick, you should first check the opening of the air barrier and adjust the oil needle. If there is no obvious effect, remove the air filter to see if the machine works better. When the above methods are ineffective, finally disassemble the carburetor to check the oil surface and measuring holes in the float chamber.

In order to solve the problem of mixed gas over-thick, the following are several effective solutions: check whether the front and rear oxygen sensors are working normally. The oxygen sensor can adjust the fuel injection of the vehicle in real time. Once the oxygen sensor fails, the vehicle will not be able to independently adjust the injection of fuel. Check the air intake system and clean up the air filter and air intake pipe.

The excessive concentration of car mixture is caused by sensor failure or damage to sensors such as air flow meters.

Solution: If the intake pressure is abnormal or the air filter is seriously blocked, the air intake is relatively small, and the injection amount of fuel remains unchanged, it will lead to excessive mixing gas. It costs 50~80 yuan to replace the air intake filter, and 250~300 yuan to replace the air intake pressure sensor.

How to deal with the mixture that is too thick?

1. In order to solve the problem of excessive concentration of mixed gas, the following are several effective solutions: check whether the front and rear oxygen sensors are working properly. The oxygen sensor can adjust the fuel injection of the vehicle in real time. Once the oxygen sensor fails, the vehicle will not be able to independently adjust the injection of fuel.Check the air intake system and clean up the air filter and air intake pipe.

2. When the mixed gas is too thick, you should first check the opening of the air barrier and adjust the oil needle. If there is no obvious effect, remove the air filter to see if the machine works better. When the above methods are ineffective, finally disassemble the carburetor to check the oil surface and measuring holes in the float chamber.

3. Only by finding out the cause of the thickening of the mixed gas is the fundamental way to solve the idling instability. There are generally the following six reasons why the mixed gas is too thick. (1) The air filter equipped with the engine is large, while the air filter used now is small, which causes the mixed gas to be too thick due to insufficient air flow.

Engine mixtureOver-dense performance and cause fault judgment and elimination

1. If the engine mixture is too thick, it may cause a variety of faults. One of the faults is that when the mixed gas is too thick, it can be seen that there is a gasoline leak at the valve shaft, and the engine power is insufficient, it is not easy to accelerate, black smoke is discharged, and the sound of "fluttering, puffing" is made. The spark plug accumulates too much carbon, and when it is serious, it will automatically shut down and cannot be started.

2. Take a gasoline car as an example, if the mixture is too thick, there will be the following faults: - black smoke comes out of the exhaust pipe when accelerating; - the engine is unstable and there is a "travelling" phenomenon when idling; - it is difficult to start when the car is hot; - there is a flat tire when the exhaust pipe accelerates.

3. The car's mixed gas is too thick may be due to the following reasons: air filter blockage; high-pressure oil pump failure; carbon accumulation in the throttle valve.Cause of failure 1: The air filter is blocked. The maintenance technician removed the air filter and checked whether there were too many internal impurities.

4. Tell the ECU to reduce the amount of fuel injection to prevent the mixture from being too thick. Summary and analysis: The main reason why the car mixture is too thick is that the long-term fuel correction is less than 0.8. To solve this fault, you need to check the fuel system, intake and exhaust system and related sensors, and check the data flow of the engine after troubleshooting.

5. Fault diagnosis and elimination of excessive gas mixture in automobiles: a. Check whether the oil plane of the float chamber is too high. B. If the oil plane is normal, check whether the air barrier is open and whether the air filter is dirty and blocked. C. If the oil plane is too high, the oil plane should be adjusted.

6. The main reason for the excessive concentration of mixed gas is: air filter blockageOr the air barrier valve is not fully opened, resulting in a decrease in the amount of air mixed with gasoline, improper adjustment of the carburetor, the oil level of the float chamber is too high, and the main fuel injection needle and the main fuel injection nozzle are worn, thus increasing the amount of gasoline mixed with the air.

How to repair the reason why the mixed gas is too thick

1. So you can replace the new fuel injector for repair. If the fuel injector is damaged and it is in a normal open state, it will increase the amount of fuel injection, resulting in too thick mixed gas. If the mixed gas is too thin in the engine, it will be easier to deal with.

2. Check whether there is a gas leak in the gas pipeline. Check whether there is scale in the furnace body. If so, clean the furnace body with the corresponding medicine according to the instructions.Check whether the mixing valve is working normally. If not, replace the mixing valve according to the instructions.

3. The main reason why the mixed gas is too thick is that the wind damper of the vehicle is not open. When the air barrier is closed, the air cannot fully enter the fuel system, resulting in excessive concentration of the mixed gas.

4. The excessive concentration of the car mixture is caused by sensor failure or damage to sensors such as air flow meters.

Is the engine mixture too thick?

The engine mixture is too thick, which may cause a variety of failures. One of the faults is that when the mixed gas is too thick, it can be seen that there is a gasoline leak at the valve shaft, and the engine power is insufficient, it is not easy to accelerate, black smoke is discharged, and the sound of "fluttering, puffing" is made. The spark plug accumulates too much carbon, and when it is serious, it will automatically shut down and cannot be started.

The car mixture is too thick: too much fuel injection; too thin means: insufficient fuel injection. The main reason why the mixed gas is too thin: (1·) Various air intake sensors cannot accurately detect the air intake, resulting in insufficient oil injection (2) Too much carbon accumulation, and the oil injection is adsorbed by carbon accumulation. ( 3) The closed-loop control of the oxygen sensor fails.

The reasons for the excessive concentration of the mixed gas include excessive gasoline pressure, dripping of the fuel injector, failure of the intake air flowmeter, the failure of the oxygen sensor, etc. Excessive pressure of gasoline is mainly caused by damage to the fuel pump and fuel pressure regulating valve, which will cause too much oil to be sprayed into the fuel injector, thus thickening the mixture.
