Is the carbon canister solenoid valve with a car displacement of 1 0 and 1 4 universal?

Start the engine and run at idle speed.

Remove the pipe connecting the fuel tank, and then you can feel the suction phenomenon at the joint of the carbon canister, and this suction phenomenon is intermittent, and the frequency is about two or three times a second; If there is no suction phenomenon, it means that the solenoid valve is stuck in the closed state.

Remove the plug of the solenoid valve of the canister, if the suction phenomenon stops, it means that the solenoid valve is working normally, if it still suctions, it means that the solenoid valve is stuck in the open state.

Activated carbon has adsorption function, when the car is running or stalling, the gasoline vapor from the fuel tank enters the upper part of the activated carbon tank through the pipeline, and the fresh air enters the activated carbon tank from the lower part of the activated carbon canister. After the engine is turned off, the gasoline vapor is mixed with fresh air in the tank and stored in the activated carbon canister, when the engine is started, the electromagnetic valve of the fuel evaporation purification device installed between the activated carbon canister and the intake manifold is opened, and the gasoline vapor in the activated carbon canister is sucked into the intake pipe to participate in combustion.

The general life of the solenoid valve of the automobile carbon canister can be replaced with an activated carbon canister at 6 to 100,000 kilometers.

The instruction manual of many models requires a carbon canister to be replaced once every 40,000 kilometers, but in fact, the service life of the carbon canister is often longer, and it can reach 6 to 100,000 kilometers without special symptoms.

Related information: carbon canister, carbon canister solenoid valve and related pipe fittings together constitute a carbon canister system, the carbon canister collects volatile gasoline, stores it, and then sends it to the intake manifold to participate in combustion, which not only saves fuel, but also protects the environment, which can be described as killing two birds with one stone. However, if there is a problem with the carbon canister, it is inevitable that the fuel consumption will increase, because the ECU controls the amount of fuel injection and calculates the gasoline in the carbon canister for secondary use at the same time, that is, if there is a problem with the carbon canister, it is easy to cause the mixture combustion is no longer sufficient.

Therefore, it is found that the fuel consumption is particularly high, and there is reason to suspect whether there is a problem with the carbon canister system.

A canister solenoid valve is a device installed in a car to reduce air pollution caused by fuel evaporative emissions and increase fuel efficiency at the same time. When the car starts, the solenoid valve opens, releasing the adsorbed fuel vapor as fuel into the intake line and into the engine combustion.

If the solenoid valve is broken (air leakage), the volatile oil vapor has entered the engine before the ignition, resulting in too much oil vapor in the engine, and the so-called flooded cylinder may occur, and there will be a second ignition or weak ignition.

The automobile carbon canister is an important component in the control system of automobile emission land key, which reduces the pollution to the environment by absorbing and storing harmful gases in the engine exhaust gas. The solenoid valve is a key component that controls the flow of gas in the canister.

Normally, the solenoid valve of the automobile carbon canister works according to a certain control logic, that is, when the engine is running, the solenoid valve will be closed, and the gas in the carbon canister will be sucked into the engine combustion chamber for combustion, so as to achieve the purpose of reducing harmful gas emissions. However, if the canister solenoid valve is always on, that is, the solenoid valve remains open all the time, then some effects will occur.

First of all, the gas in the carbon canister cannot be emptied in time, resulting in insufficient volume of the carbon canister and the inability to continue to absorb and store harmful gases in the engine exhaust gas, thus affecting the normal operation of the automobile emission control system.

Secondly, the solenoid valve of the canister will cause the engine to run unsteadily, because the gas in the canister will interfere with the proportion of air and fuel in the combustion chamber of the engine, affecting the combustion efficiency of the engine, thereby reducing the performance and fuel economy of the car.

Finally, the solenoid valve of the carbon canister will often lead to excessive pollutant emissions, because the gas in the canister cannot be emptied in time, and harmful gases will be discharged into the atmosphere through the exhaust pipe, thus causing greater pollution to the environment.

Therefore, in order to ensure the normal operation of the automobile emission control system and reduce the pollution to the environment, we should regularly inspect and maintain the automobile carbon canister solenoid valve to ensure that it works according to the normal control logic. If it is found that the solenoid valve of the canister is normal, it should be repaired or replaced in time to avoid the occurrence of the above effects.
