Why Does the Exhaust Smell Strongly of Gasoline?
1 Answers
Reasons for a strong gasoline smell in the exhaust are as follows: Gasoline pipe interface leakage: Leakage at the gasoline pipe interface causes the gasoline smell to enter the car through the air conditioning system. Open the engine compartment cover to check for leaks. If there is a leak, tighten the interface promptly or go to a repair shop for maintenance. Rubber hose aging: Rubber hoses in the engine compartment may age over prolonged use. Older vehicles are more prone to hose aging, which can lead to gasoline leaking into the engine compartment. Inability to restore activity: Issues with the gasoline vapor canister (charcoal canister), such as overfilling the fuel tank for a long time, can cause the activated carbon in the canister to become saturated, making it unable to restore its activity in time. Incomplete combustion: Incomplete combustion of gasoline results in unburned fuel being expelled. Sometimes, when the fuel tank is overfilled, although the fuel filler neck doesn't leak, gasoline may still flow into the canister through the pipes. Consequently, when the canister releases vapor, gasoline is also released along with it.
