Abstract

The engine according to the invention comprises a cylinder body (101) including at least one power piston/cylinder combination (104, 103) and at least one auxiliary piston/cylinder combination (108, 102) with the said combinations disposed in coaxial relationship, a separating wall disposed between adjacent piston/cylinder combinations, a connection rod (117) coaxially interconnecting the pistons (104, 108) for synchronous movement thereof between top- and bottom-dead-centre positions of the pistons and sealingly passing through said separating wall or walls, a connecting rod (106) and crank-shaft for converting reciprocal motion of the said combination into a rotational output, an exhaust port (109) for discharging exhaust gases from the cylinder (103) when the power piston (104) is in the region of bottom-dead-centre, an inlet port (111) including a one-way a valve (112) in communication with at least that auxiliary cylinder (102) adjacent the power cylinder, means for controlling operation of the said one-way valve (112) in accordance with the engine firing cycle, a gas transport passage (113) interconnecting a power cylinder (103) and an adjacent auxiliary cylinder (102), and a valve (114) for controlling transportation of gas through the passage (113), a gas pump chamber (102 min ) disposed on at least that side of an auxiliary piston (108) remote from an adjacent power piston (104) for compressing gaseous media, and means (110, 110 min ) for igniting a fuel/gas mixture in each power cylinder or injecting fuel into each power cylinder.
