Patent ID: 7100546

Claim:
An internal combustion engine comprising: a) at least one hydraulic cylinder assembly containing therein a working liquid, said at least one hydraulic cylinder assembly configured so as to be displaceable in a substantially reciprocating movement; b) at least one impulse turbine deployed within said hydraulic cylinder assembly, said at least one impulse turbine mechanically linked to a rotatable output shaft, said at least one impulse turbine configured such that movement of said working liquid onto said at least one impulse turbine during said reciprocating movement of said hydraulic cylinder assembly effects axial rotation of said at least one impulse turbine; c) at least a first and second pistons mechanically linked to said hydraulic cylinder assembly; and d) at least a first and second cylinders configured to slidingly receive said at least a first and second pistons such that movement of each of said pistons is effected within said first and second cylinders by combustion of fuel in combustion chambers defined by said at least a first and second pistons and said at least a first and second cylinders; wherein movement of said pistons affects said reciprocating movement of said at least one hydraulic cylinder assembly and said hydraulic cylinder assembly is slidebly received on hydraulic cylinder guides.
