ABSTRACT:
An internal combustion piston engine utilizing a catalyst to promote combustion and not requiring spark ignition. A catalyst member is provided within the engine cylinder. Air is supplied to the cylinder and is compressed by a piston. At or near the point of maximum compression, fuel is contacted with the catalyst, preferably from the side of the catalyst opposite the piston. The fuel and air mix to initiate combustion and the air-fuel mixture passes through the catalyst member, completing the combustion. The operation can result in relatively complete combustion of the fuel at a relatively low temperature of about 1800.degree. to 3300.degree. or 3500.degree. F. so that little or no undesirable components are present in the engine exhaust, especially the exhaust may have a low content of nitrogen oxides.
