A two-stroke reciprocating piston engine. The engine principally consists of an expansion cylinder and a compression cylinder, and an expansion chamber and a combustion chamber. When pistons of the expansion cylinder and compression cylinder move from a bottom dead center to a top dead center, gas in the expansion cylinder is compressed in the expansion chamber, gas in the compression cylinder is compressed in the combustion chamber, a water spray nozzle sprays water towards the high temperature and high pressure gas in the expansion chamber, and when the water encounters the high temperature and high pressure gas, the water is rapidly vaporized. At the same time, an oil spray nozzle sprays a fuel into the combustion chamber, a spark from a spark plug ignites the combustible gas of the combustion chamber, the high temperature and high pressure gas produced by the combustion pushes open a valve of the combustion chamber. |
