Gas fueled internal combustion engine

Abstract

Abstract AN INTERNAL COMBUSTION ENGINE IS POWERED BY A GASEOUS FUEL SUCH AS HYDROGEN. THE GAS IS STORED IN LIQUID FORM IN AN INSULATED TANK. A HEAT EXCHANGER ASSOCIATED WITH THE TANK CONVERTS THE LIQUID TO A GAS AT A CONTROLLED RATE DEPENDENT UPON THE DEMANDS OF THE ENGINE. THE GAS IS THEN FED TO THE ENGINE INDUCTOR. IN THE INDUCTOR, THE GASEOUS FUEL IS MIXED WITH AIR AND THEN PUMPD UNDER RELATIVELY HIGH PRESSURE INTO THE ENGINE COMBUSTION CHAMBERS TO ACHIEVE A HIGH COMPRESSION RATIO. HIGH ENERGY STEAM EXHAUSTING FROM THE COMBUSTION CHAMBERS IS CIRCULATED THROUGH THE HEAT EXCHANGER WHERE IT GIVES UP SOME OF ITS HEAT AND THENCE BACK TO THE ENGINE COMBUSTION CHAMBERS WHERE IT FUNCTIONS AS A COOLING AND WORKING MEDIUM. ANY FLAMMABLE GAS WHICH FINDS IT WAY INTO THE CRANKCASE IS SCAVENGED THEREFROM IN ORDER TO MINIMIZE THE LIKELIHOOD OF EXPLOSIONS AT THAT LOCATION.
