What Causes the Buzzing Noise When Driving a Car?

[Marie]

Car driving with a buzzing noise is caused by: excessive carbon deposits in the engine, poor gasoline filtration, low-quality gasoline, aging spark plugs, engine malfunction, or cylinder failure. Solutions to the buzzing noise when driving a car include: 1. Replace the engine oil; 2. Clean carbon deposits from the engine; 3. Replace the spark plugs; 4. Conduct a comprehensive inspection and repair of the vehicle. The working principle of the engine: 1. Mix air and gasoline in a certain ratio to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to generate thermal energy; 3. The high-temperature and high-pressure gas acts on the top of the piston, driving the piston to perform reciprocating linear motion, and the mechanical energy is output through the connecting rod, crankshaft, and flywheel mechanism.
