The principle of automobile engine
In contrast, the internal combustion engine is more efficient than the external combustion engine, cheaper than the gas turbine, easier to add fuel than electric vehicles. These advantages make most modern cars use reciprocating internal combustion engines.
(2) splash lubrication: the use of the engine when working with some moving parts (mainly crankshaft and camshaft) splashing oil droplets and oil mist, the friction surface of a way of lubrication.
Gasoline engines convert gasoline energy into kinetic energy to drive cars, and the easiest way is to get kinetic energy by burning gasoline inside the engine. Therefore, the car engine is an internal combustion engine - the combustion takes place inside the engine
