Starter according to the working principle is divided into DC starter, gasoline starter, compressed air starter and so on. Most of the internal combustion engine is a DC starter, which is characterized by compact structure, simple operation and easy maintenance. Gasoline starter is a clutch with a variable speed mechanism of small gasoline engine, power and less affected by the temperature, can start a large internal combustion engine, and suitable for alpine areas. Compressed air starter is divided into two categories, one is the compressed air in accordance with the work sequence into the cylinder, one is the use of pneumatic motor drive flywheel. The use of compressed air starters is close to gasoline starters, and is usually used for large internal combustion engines.
