The new Elysee engine buzzes with the accelerator pedal.

This may be caused by engine knocking for the following reasons:

① There is something wrong with the ignition time.

② The air-fuel ratio is incorrect.

③ The octane number of fuel is too low or the cleanliness of fuel is not enough.

First check the ignition time of the engine and check whether the mixture is normal. If the ignition time and mixture are normal, it may be an oil quality problem. It is suggested to add gasoline with higher label.

An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc. ), external combustion engine (Stirling engine, steam engine, etc. ), motor, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is suitable for both power generation devices and complete machines (such as gasoline engines and aero-engines) including power devices. The engine was first born in Britain, so the concept of engine also originated in English. Its original meaning refers to "a mechanical device that generates power".
