This invention relates to a reciprocating internal combustion engine including a separate gas chamber. In more detail, the engine according to the invention comprises a cylinder body including at least one power piston/cylinder combination and at least one auxiliary piston/cylinder combination with the said combinations disposed in coaxial relationship, a separating wall disposed between adjacent piston/cylinder combinations, a connection rod coaxially interconnecting the pistons for synchronous movement thereofbetween top-and bottom-dead-centre positions of the pistons and sealingly passing through said separating wall or walls, a connecting rod and crank-shaft for converting reciprocal motion of the said combination into a rotational output, an exhaust port for discharging exhaust gases from the power cylinder when the power piston is in the region of bottom-dead-centre, an inlet port including a one-way in valve in communication with at least that auxiliary cylinder adjacent the power cylinder, means for controlling operation of the said one-way valve in accordance with the engine firing cycle, a gas transport passage interconnecting a power cylinder and an adjacent auxiliary cylinder, and a valve for controlling transportation of gas through the passage, a gas pump chamber disposed on at least that side of an auxiliary piston remote from an adjacent power piston for compressing gaseous media, and means for igniting a fuel/gas mixture in each power cylinder or injecting fuel into each power cylinder.
