- Definição1
- A type of heat engine that changes chemical energy in fuel and air into mechanical energy. A mixture of fuel and air is draw into a cylinder as a closefitting piston moves downward. The valve through which the fuel-air mixture entered the cylinder closes, and the piston moves up, compressing the mixture. As the piston nears the top of its stoke, the compressed mixture is ignited, and it burns. The burning gases heat the air in the cylinder, and as it expands, it pushes the piston downward. The reciprocating piston is connected to a crankshaft throw by a connecting rod. As the piston moves up and down in the cylinder, the connecting rod rotates the crankshaft.

- Definição3
- An engine that converts the chemical energy in the fuel plus air into mechanical energy by providing reciprocating movement to the pistons. This movement is further converted into rotary motion by the connecting rods and crankshaft. A reciprocating engine is usually a four-stroke engine.
