An internal combustion steam engine comprises primary and working sections 1, 10 and means for injecting water or steam, wherein the engine is configured so that a mixture of steam and exhaust gases from the primary section are supplied to the working section. The primary section may comprise a small capacity engine having an inlet valve 3 for entry of air and an exhaust valve 4 for the outlet of exhaust gases following ignition of a mixture of air and fuel. The exhaust valve may be connected to an inlet valve 7 of the working section via a passage 6, which preferably comprises an enlarged section forming an annular chamber. The water or steam injection means may be a water injector 5 that provides water to the passage, where the water is converted to steam.
