What Causes the Engine Resonance and Buzzing Sound During Acceleration?

[StRebecca]

The reason for engine resonance and buzzing sound during acceleration is: the engine is not running smoothly. You should check whether the cylinder pressure, ignition spark energy, throttle position sensor, idle air control valve, and engine mounts are normal. An engine is a machine that can convert other forms of energy into mechanical energy. The engine can refer to either the power generation device or the entire machine including the power device. Its types include internal combustion engines, external combustion engines, gas turbines, and electric motors. The components of an engine include: 1. Valve train; 2. Crankshaft and connecting rod mechanism; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Starting system; 7. Fuel supply system.
