What Causes White Smoke from Engine Exhaust?
1 Answers
Engine exhaust emits white smoke due to: 1. The engine temperature being too low; 2. Incomplete combustion of some fuel, resulting in white smoke being expelled along with the exhaust gases; 3. Water in the fuel supply system, which can cause white smoke during startup. Methods for engine maintenance include: 1. Using high-quality engine oil; 2. Regularly cleaning the radiator to remove scale; 3. Maintaining a reasonable engine speed; 4. Using qualified coolant. The steps for cleaning the engine are: 1. Park the vehicle in a dust-free area after turning off the engine; 2. Use compressed air or a vacuum cleaner to blow dust off the engine; 3. Wipe away dust with a semi-dry cloth; 4. Open the engine hood to let it dry.
