Abstract

The invention discloses an engine starting system, an engine and an engine starting method, and belongs to the technical field of engines. The engine starting system comprises a cylinder, an electromagnetic valve, a controller, an ignition switch and a rotating speed sensor, wherein the electromagnetic valve is configured to control gas in the cylinder to be connected and disconnected with the atmosphere, and is a normally closed electromagnetic valve, the ignition switch is configured to control the electromagnetic valve to be opened and closed, the electromagnetic valve, the ignition switchand the rotating speed sensor are all in signal connection with the controller, and the rotating speed sensor can detect the rotating speed of the engine and feed back the rotating speed of the engine to the controller.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine starting system, an engine including the starting system and an engine starting method. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generation device, but also refers to the whole machine including the power device (such as: gasoline engine, aero engine). [0003] And if the engine will work normally, it needs to start successfully at first, and the starting performance is an important indicator of the engine. In the prior art, when starting, the starting resistance of the engine is ve...
