Engine timing

Ignition timing. Ignition timing means that when the compression stroke of the engine ends and the piston reaches the peak stroke, the ignition system provides high-voltage spark to the spark plug to ignite the compressed mixture in the cylinder to do work. This time is the ignition timing, which is the engine timing. An engine is a machine that can convert other forms of energy into mechanical energy. Engine is not only suitable for power generation device, but also refers to the whole machine (such as gasoline engine and aero-engine) including power device. Automobile engines can be divided into two categories: gasoline engines and diesel engines. Their basic structures are the same, and they are composed of two major mechanisms and five major systems, namely crank-connecting rod mechanism, gas distribution mechanism, oil supply system, lubrication system, cooling system, ignition system and starting system.
