How much does it cost to replace a carbon canister solenoid valve? If the carbon canister solenoid valve is broken, will it waste fuel? Can it still be turned on if it is broken?

How much does it cost to replace a carbon canister solenoid valve

If the carbon canister solenoid valve is damaged, it needs to be replaced in time, otherwise it will increase fuel consumption and affect the normal operation of the car engine. As for the price of the carbon canistersolenoid valve, the price of different models is also different. The price of buying it yourself varies greatly, ranging from tens to one It ranges from two hundred yuan. The price of replacing the carbon canister solenoid valve at a 4S store is generally around 200-300 yuan, depending on the model.

Can the canister solenoid valve be opened if it is broken?

Gasoline is a volatile fuel. The fuel in the tank will evaporate quickly and increase the pressure inside the tank. When the car is started, the active The solenoid valve of the carbon canister is opened in a timely manner, and the absorbed fuel vapor is poured back into the intake manifold to release the pressure. The adsorption capacity of the activated carbon in the can is used to temporarily adsorb this part of the fuel vapor to prevent the engine from running. Fuel vapor escapes into the atmosphere. If the solenoid valve is broken, it will always open, which may cause ignition difficulties.

Will the carbon canister solenoid valve be broken and waste fuel?

The carbon canister solenoid valve is a device installed on a car to reduce air pollution caused by fuel evaporative emissions and increase fuel efficiency at the same time. When the car is started, the solenoid valve opens, releasing the adsorbed fuel vapor into the intake pipe and entering the engine for combustion. So, does the carbon canister solenoid valve affect fuel consumption?



Due to the tightness of the fuel tank, fuel consumption will cause negative pressure inside the fuel tank. Under the action of negative pressure, the gasoline will be thicker than under normal pressure. Evaporates oil vapor easily. When the engine is shut down, the carbon canister mixes the oil vapor emitted from the fuel tank with air and stores it in the activated carbon micropores in the carbon canister to prevent the oil vapor from dissipating into the atmosphere. When the engine is started, the solenoid valve installed between the activated carbon canister and the intake manifold opens, sending the oil vapor in the carbon canister as fuel to the engine to participate in combustion. The carbon canister solenoid valve reduces both emissions and fuel consumption. Therefore, to a certain extent, the carbon canister solenoid valve will affect fuel consumption.



It is precisely because the carbon canister solenoid valve can reduce fuel consumption, so if the carbon canister solenoid valve is broken, it will also increase fuel consumption to a certain extent. It will consume more fuel. If the carbon canistersolenoid valveIf it breaks down, the car will leak air. Before the car is ignited, gasoline vapor will evaporate into the cylinder. This will cause the concentration of the combustible mixture to be too high and make it difficult to start the car. This is very difficult. Gas-guzzling. At the same time, because the mixture is too rich, resulting in insufficient combustion, the engine ECU will make corrections based on judgment, resulting in thinner fuel injection, which will also lead to increased fuel consumption.
