What Causes the Smell of Burning After a Car Shuts Off?
1 Answers
The reasons for the smell of burning after a car shuts off are as follows: 1. New car: It is generally normal for a new car to have this smell. Various rubber and plastic components in a new car can produce this odor under high temperatures, which will gradually fade away with use. 2. Gasoline smell: Starting the car in winter, due to low temperatures, makes it harder to atomize gasoline, affecting combustion. Some unburned gasoline molecules may be expelled through the exhaust pipe and then enter the car via the external circulation. 3. Brake pad friction smell: If the handbrake is not fully released, the brake pads will continuously rub while driving, producing a metallic burnt smell. 4. Exhaust pipe scraping: The exhaust pipe can get very hot during driving. If a plastic bag sticks to it, the plastic may melt, producing a burnt rubber smell.
