How to clean the intake valve of automobile engine, please ask experts for advice.

1. Choose oil with powerful cleaning function.

The cleaning principle of engine oil is that the engine oil circulates and filters carbides, sludge and worn metal particles on the internal parts of the engine to achieve a certain cleaning effect.

At the same time, engine oil can also inhibit the formation of carbon deposits, so you must choose engine oil with strong cleaning function when maintaining your car.

2, playing infusion bag or bottle

The bottle is filled with pressurized atomized cleaning agent, and the cleaning agent is pumped into the air inlet to have a solvent dissolution reaction with the carbon deposits in the throttle valve, fuel injector and other parts. Then the cleaned carbon deposits are blown out of the engine by using the high speed of the engine. The bottle will discharge clean carbon deposits through the exhaust system, but if the carbon deposits are very serious, it will cause blockage or even damage to the three-way catalytic system.

Extended data

The main causes of carbon deposition are bad driving habits and substandard gasoline filling. The power of the engine comes from the fact that when the piston of the engine moves downward, the mixture of gasoline and air is sucked into the cylinder, and then the upward piston compresses the oil and gas into highly combustible gas, and finally the spark plug ignites it. The piston is pushed by this powerful explosive force, so the engine generates power.

The power source in the engine is mixed gasoline, which must enter the combustion chamber through the intake valve, and a small amount of gasoline will adhere to the intake valve. When the engine is at high temperature, the carbon and oxygen compounds, paraffin wax and gum in gasoline can't be completely burned, but will be burned into coke. If there is scale on the nozzle, the sprayed gasoline will be in a poor atomization state, and the uneven mixing of gasoline and air will increase the condensation of gasoline in the intake valve.
