Abstract: A sparked reciprocating internal combustion two-stroke steam engine including an engine casing, a crankshaft rotatable about a crankshaft axis, a cylinder arranged inside the engine casing, a piston 1 arranged inside the cylinder to movably reciprocate along a reciprocating axis between a top dead center position distal from the crankshaft and a bottom dead center position proximal to the crankshaft and operatively connected to the crankshaft such that the reciprocating piston imparts a rotational movement to the crankshaft, a combustion chamber defined within the cylinder between the engine casing and a head of the piston opposite the crankshaft, an intake valve, an exhaust valve, a fuel injector to directly inject fuel into the combustion chamber, a water injector to directly inject water into the combustion chamber at a location below the top dead center position of the piston, and a spark plug, where the intake valve is in fluid connection with a compressed gaseous oxidizer supply configured to feed compressed gaseous oxidizer through the intake valve to the combustion chamber.
