What is the function of the carbon canister solenoid valve? What are the symptoms of the carbon canister solenoid valve being normally open?

Carbon canister electromagnetic What does the valve do?

1. The carbon canister solenoid valve is a device installed on a car or motorcycle to reduce air pollution caused by fuel evaporation emissions and increase fuel efficiency at the same time.

2. When the engine is turned off, the vehicle activated carbon canister begins to absorb the oil vapor emitted from the fuel tank, and is firmly locked in the activated carbon micropores in the canister to prevent the oil vapor from dispersing into the atmosphere.

3. When the engine starts, The solenoid valve opens, releasing the adsorbed fuel vapor into the intake pipe and entering the engine for combustion.

The carbon canister solenoid valve is normally Symptoms of prescription

< span style="font-size: 16px;">1. Increased fuel consumption: When the solenoid valve of the carbon canister is normally open, as long as the engine is started, the gasoline vapor adsorbed in the carbon canister will enter the cylinder to participate in combustion, which will Causes increase in vehicle fuel consumption.

2. Difficulty starting the engine: Since the carbon canister solenoid valve is always open, the air in the intake pipe will be filled with gasoline vapor. When the engine starts, the excessively rich combustible mixture will cause the engine to malfunction. Difficulty starting or even stalling.

3. Increased carbon deposits: Due to the enrichment of the combustible mixture, incomplete combustion of gasoline results in the accumulation of carbon deposits.
