FLOW-THROUGH INTERNAL COMBUSTION ENGINE

摘要

A flow-through internal combustion engine comprising an arrangement for compressing air, a combustion chamber with a fuel injection arrangement and optionally an arrangement for water injection, and an arrangement for expanding exhaust gas, wherein the expansion arrangement (4) is constituted by a piston arrangement, especially of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber (2) is unidirectional. In an alternative solution the air compressing arrangement (1) and the expanding arrangement (4) are constituted by the same piston arrangement, especially one of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber is also unidirectional.
