Claim:
1. A high-efficiency reciprocating piston engine, driven by pressurized air or gas tank, said engine being adapted to operate by sucking a further supplementary air from an outside environment and discharging, at an end of an operating cycle, non-polluted air into said environment, said engine also including turbo-alternator means, heat exchanger means and one or more fluid heater means, wherein said engine comprises at least a cylinder and at least a piston movable in said cylinder, a cylinder head, a cylinder head pre-chamber forming a plenum chamber with said cylinder having a size proportional to a displacement of said engine and to a power to be achieved thereby, unidirectional valves, applied to one or more suction ducts formed in said cylinder head, thereby allowing said piston to draw, during a downward stroke thereof, said supplementary air from said outside environment to convey said supplementary air into an expansion chamber, wherein said valves are designed to overcome any resistance generated by a vacuum in said cylinder in a passive mode of operation of said engine, filter elements being arranged in said suction ducts, for filtering said supplementary air from said outside environment to said cylinder and engine, said supplementary air, after said engine operating cycle being reintroduced again, in a filtered non-polluted condition, into said outside environment in an upward stroke of said piston through an outlet valve and outlet ducts, said engine further comprising said turbo-alternator means, said heat exchanger means and said one or more fluid heater means for heating said air coming from said pressurized air tank to said cylinder and said cylinder head.
