What Causes the Smell of Gasoline After Ignition?

[SerenityLynn]

Reasons for the smell of gasoline after a cold start include oil leakage in certain areas and fuel injector malfunction. If the fuel injector malfunctions: If the fuel injector malfunctions, gasoline cannot be fully atomized during a cold start, leading to incomplete combustion. This results in a noticeable gasoline smell in the exhaust. Fuel line leakage: If there is a leak in the car's fuel tank or fuel line, consider whether the car has experienced a significant collision. The owner can check for fuel tank leakage by observing whether there are oil drops on the ground where the car is parked or nearby. Normal phenomenon: Sometimes, during a cold engine start in winter, due to the difficulty in ignition caused by cold weather, some gasoline may be expelled from the exhaust pipe, resulting in a gasoline smell. This is a relatively normal phenomenon.
