Abstract:
An engine capable of being run on various types of fuels including heavy fuels being one of diesel fuel, JP5, Jet A, JP8, kerosene, and gasoline and alcohol based fuels, said engine comprising:an engine block having at least one cylinder defining at least one cylinder chamber;a cylinder head mounted on said cylinder and defining a combustion chamber;at least one piston received within said at least one cylinder chamber and moveable therealong, said piston connected to a crankshaft for driving the crankshaft;a fuel delivery system for delivering a combustible mixture of fuel and air to said combustion chamber with the combustible mixture being delivered at a sonic rate of flow so as to substantially atomize the fuel in the air for enhanced ignition; andat least one igniter mounted adjacent said combustion chamber and having an ignition zone at which the combustible mixture is ignited to cause combustion of the combustible mixture within said combustion chamber for driving said piston, wherein said fuel delivery system includes a fuel delivery valve including a valve body defining a valve passageway having an inlet end and an exit end defining a valve opening, a valve member received in said valve body and movable along said valve passageway, said valve member having an air passage formed therein and which communicates with the valve opening as said valve member is moved along said valve passageway between open and closed positions, and biasing means for maintaining said valve member in the closed position until the combustible mixture is directed through said air passage at an opening differential pressure sufficient to overcome said biasing means and open said valve opening so as to create a sonic velocity flow of the combustible mixture through said fuel delivery valve.
