Internal combustion and waste heat steam engine having a heat recovery steam generator exhaust manifold

An improved internal combustion and steam engine having an engine block defining a cylinder bore forming a combustion chamber and carrying a reciprocally moving piston within the cylinder bore, the piston interconnected to a connecting arm communicating with a crankshaft opposite the piston to rotate the crankshaft as the piston moves reciprocally within the cylinder bore, the engine further having a fuel supply and an air supply, the improvement comprising in combination:

• an air inlet port and an exhaust port defined in a circumferential surface of the cylinder bore, the air inlet port communicating with an air inlet passage and an air moving means for injection of air into the combustion chamber and the exhaust port communicating with an exhaust passage so that combustion products exit the combustion chamber, the position and dimensions of the air inlet port and the exhaust port are such that as the piston moves reciprocally within the cylinder bore the air inlet port and the exhaust port are opened and closed;
• an injector communicating with the combustion chamber and the fuel supply to inject fuel into the combustion chamber resulting in ignition of the injected fuel when the piston compresses the air fuel mixture within the combustion chamber to ignition temperature;
• a heat recovery steam generator communicating with the exhaust ports to collect and channel combustion products exiting the exhaust ports, the heat recovery steam generator defining an interior channel carrying fluid filled coils which are exposed to the combustion products causing the fluid within the coils to absorb heat and become steam which is communicated to the injector for injection of the steam into the combustion chamber to increase engine performance and to absorb combustion heat;
• and
• an injection pump communicating with the fuel supply to meter the volume of fuel injected into the combustion chamber through the injector and the timing of the injection of the fuel.
