What Causes Odors Before and After Starting the Car?

[Henderson]

The reason for odors before and after starting the car is: gasoline smell, because the internal temperature has not reached the normal operating temperature when the engine is just ignited, and the gasoline does not burn completely. Methods to remove odors in the car include: 1. Place fruits with strong adsorption capabilities such as grapefruit peels, pineapples, and lemons; 2. Place white vinegar in the car, which has sterilizing and cleaning abilities; 3. Use activated charcoal to eliminate odors; 4. Remove protective films inside the car; 5. Open windows for ventilation; 6. Spray an appropriate amount of air freshener. Solutions for a car that won't start include: 1. Check if the battery is low on power and charge it; 2. Repair a damaged fuel pump promptly; 3. Check if the fuel level is sufficient and add enough fuel; 4. Check if the engine sensor is damaged.
