Internal combustion steam engine

Abstract

A sparked reciprocating internal combustion two-stroke steam engine comprising an engine casing, a crankshaft (16) rotatable about a crankshaft axis, a cylinder (2) arranged inside said engine casing,a piston (1) arranged inside said cylinder to movably reciprocate along a reciprocating axis between a top dead center position distal from said crankshaft and a bottom dead center position proximalto said crankshaft and operatively connected to the crankshaft such that the reciprocating piston imparts a rotational movement to the crankshaft, a combustion chamber (17) defined within said cylinder between the engine casing and a head of the piston opposite said crankshaft, an intake valve (3A), an exhaust valve (3B), a fuel injector (4) to directly inject fuel into said combustion chamber, awater injector (6) to directly inject water into said combustion chamber at a location below said top dead center position of the piston, and a spark plug (5), wherein the intake valve is in fluid connection with a compressed gaseous oxidizer supply (9) configured to feed compressed gaseous oxidizer through the intake valve to the combustion chamber.

Description

technical field [0001] The present invention relates to internal combustion steam engines, in particular, to internal combustion steam engines having improved efficiency, low pollution and high torque at low RPM, and to methods of operation of such internal combustion steam engines. Background technique [0002] Steam engines and internal combustion engines have been used to generate mechanical rotational power for more than 150 years. James Watt made possible existing steam engines based on reciprocating pistons by coupling low power reciprocating engines with condensers (which allowed steam to expand to subatmospheric pressures, thus enhancing the efficiency of low power reciprocating engines). The introduction of steam turbines allowed greater efficiency and expansion to the pressure of inches of mercury under our gravitational system. However, reciprocating type steam engines were used in the railroad industry throughout the 20th century when high torque was required at...
