Fuel evaporation:
Oil and gas → oil and gas separator (inside the oil tank) → adsorption/vent pipe → solenoid valve intake pipe → sol enoid valve
outlet pipe → throttle valve body assembly → intake manifold → cylinder
The fuel evaporative pollutant control system can only be checked after the cover is removed.
Check the carbon canister for cracks or damage.
Check the suction/vent pipe for cracks or damage.
Check whether the solenoid valve of the carbon canister is working properly.
Check whether the solenoid valve inlet and outlet pipes are cracked or damaged.
Check whether the hoses are bent, causing the airflow to be unsmooth.
