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. The ignition chamber is predominantly in convective heat exchange relationship with the primary combustion chamber and has at least one opening therein designed and oriented with respect to the interior thereof to create a nonturbulent circular air flow therein during the compression stroke of the engine which will cause the lighter components of the fuel charge directed therein to be concentrated adjacent a central zone where such lighter and generally more volatile components of the fuel charge will be ignited by the heat therein to thereby initiate a controlled ignition of the remaining fuel in the ignition chamber. The amount of fuel in the fuel charge directed into the ignition chamber will remain generally constant regardless of the load on the engine and its operating speed with the amount of such fuel charge depending on the engine compression ratio and the relative sizes of the ignition and combustion chambers. The amount of such a fuel charge should be as great as possible while still insuring complete fuel combustion therein.

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.

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.
