Abstract: A method and apparatus for combusting diesel, gasoline, kerosene, alcohol and other compression ignition fuels in either direct or indirect injection compression auto ignition internal combustion engines which enables such engines to operate at low compressions. The apparatus includes an ignition chamber which functions to receive a portion of the incoming fuel charge thereby concentrating such portion in an area separate from the auxiliary or primary combustion chambers.

Abstract: Pump apparatus for injecting combustible fuel under high pressure into a diesel type internal combustion engine. The apparatus includes a body having a cavity with a diaphragm therein and an adjustable variable pressure applied intermittently to one side of the diaphragm causes a selected quantity of fuel to be pumped through the cavity on the other side of the diaphragm.

Abstract: Fuel injection apparatus for injecting gasoline or other combustible fuel into the cylinders of an internal combustion engine. The apparatus includes a fuel injector body having a diaphragm through which a needle valve extends and a constant fluid pressure is maintained on one side of the diaphragm to urge the needle valve toward closed position. A higher fluid pressure is intermittently applied to the other side of the diaphragm so that the needle valve is opened to spray fuel under pressure into the internal combustion engine, and when the higher pressure is relieved the introduction of fuel is interrupted.
