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.

A filtration system for a particulate-laden stream of gas utilizes a group of fabric bags within the upper chamber of a housing as the means by which particulate matter is filtered out of the gas. The gas inlet into a lower chamber of the housing is provided with an inlet guide that directs the incoming gas against the lower side of a porous diffuser located below the group of bags and spanning at least most of the separation zone defined by the bags. Passages through the diffuser are configured to present an array of nozzles so that the gas is subjected to a pressure drop across the diffuser before flowing to the bags. The nozzle effect causes the particulate-laden gas to spread out evenly on the lower, upstream side of the diffuser and pass through the diffuser at substantially equal velocity at all passages, thereby smoothing the flow and distributing it evenly to all bags.
