Описание: Can bad spark plugs cause fuel smell?

Yes, bad spark plugs can contribute to a gasoline smell in your exhaust.
Spark plugs play a crucial role in igniting the air-fuel mixture in the engine’s cylinders.
If they’re worn out, fouled, or malfunctioning, they might not ignite the fuel properly.
This can lead to incomplete combustion, where some of the fuel doesn’t burn completely and ends up in the exhaust system.

When fuel isn’t burned properly, it can cause:

Increased Fuel Consumption:
The engine compensates for the incomplete combustion by using more fuel, which might result in a richer fuel mixture and a gasoline smell in the exhaust.

Unburned Fuel in the Exhaust:
Fuel that hasn’t been fully combusted can pass through the engine and into the exhaust system, leading to a noticeable gasoline smell.

Rough Running Engine:
Bad spark plugs can cause misfires.
