How long is the throttle?

How often must the accelerator of a car be cleaned?

How often must the accelerator of a car be cleaned? Residual essential oil (that is, a small amount of oil residue returned after crankcase separation) will remain in the throttle valve (sticky) and then mix with some impurities in the air to form so-called carbon-like substances; Whether the throttle is easy to accumulate oil depends on the engine model and throttle layout!

This design tends to deposit viscous oil on the throttle valve. After a long time, mixed with various dust impurities, carbon-like substances will be produced. Compared with the throttle valve arranged above the throttle valve manifold, the throttle valve arranged below is easier to deposit carbon, so the throttle valve is usually washed once every 50,000 kilometers.

If you drive a turbocharged car in the north (central heating in winter) and the intake valve is arranged under the manifold, then after driving for 10,000 kilometers, a thick layer of viscous mixture (actually not carbon deposit) will accumulate on the throttle, which should be decided according to the actual situation; Serious carbon deposition will lead to unbalanced mixing ratio.

Thereby causing engine vibration and increasing fuel consumption. Of course, if the carbon deposit is serious, the throttle will return to the locked position, but this situation is really rare. The carbon deposit on the throttle cannot be cleaned by pulling speed, and it can only be cleaned by hand. In addition, during long-distance and short-distance driving, because the engine is in a low temperature state.

For the intake manifold injection EFI engine, after the engine is turned off, the fuel injected into the intake manifold can not be sucked into the engine, and the atomized gas will condense on the back of the intake manifold and the low-temperature butterfly valve to form solidification, which will form carbon deposit after a long time. In case of fire, you can use the on-board computer to reset the throttle parameters.

In fact, you can automatically reset the battery by disconnecting the negative electrode of the battery, but the side effect is that you may lose short-term mileage information and clock. If the car vibrates unsteadily or the acceleration is weak when idling, it is necessary to consider whether the throttle has not been cleaned for a long time, because this situation is mainly caused by the unclean throttle.

In this case, it is recommended to go back to the store as soon as possible to check and confirm the actual situation of the butterfly valve. We clean when it's time to clean. At this time, you can clean the removed throttle. Use the professional accelerator cleaning products bought together to avoid stains. However, people's health and safety must also be protected.

Such as masks, gloves and glasses. Use both. In particular, it often travels at low speed on urban roads, never on highways, and gasoline burns incompletely, which is easy to produce carbon deposits and accumulate on the throttle, intake pipe and engine wall of automobiles. The cylinder and piston will affect the power of the car, resulting in weak acceleration when the car is driving.

If this happens, you need to clean the accelerator of the car. Because disassembly and cleaning can clean the butterfly valve more thoroughly, the disadvantage is that some air intake systems connected with the butterfly valve cannot be cleaned at the same time, and the effect of free disassembly is just the opposite. At present, this problem is completely solved, unless the big car owner absolutely refuses to dismantle the engine.

Due to the high temperature of oil and gas, the temperature drops rapidly when it reaches the butterfly valve. At this point, some steam will stick to the joint edge of the butterfly valve. When the car is turned off, some cylinders will suck the mixture into the cylinder, but it will burn without doing work. With the volatilization of gasoline, it will also reach the butterfly valve with intake branch pipe.

Because the air still contains fine dust particles, the air filter cannot completely filter, because it will adhere to oil and gas molecules and form carbon deposits over time. No matter how to clean the butterfly valve, it is necessary to reset the butterfly valve, that is, reset the learning value to make the butterfly valve return to the initial position.

The throttle on modern cars is electronic, and the throttle is controlled by a motor. If there is carbon deposit on the throttle, its position will change. After receiving the signal from the throttle position sensor, the engine computer will adjust the throttle position to correct the throttle opening. Throttle has always been the first restriction of automobile air intake.

Many car owners will be forced to clean the throttle when they go to the 4S repair shop. So how often is it appropriate to clean the throttle valve? Many people don't know the specific time, the old driver said, just master this sentence.
