Abstract
An internal combustion engine of reciprocating-piston type with injection of liquid or gaseous hydrocarbon fuel, provided with catalytic means for initiating the combustion of the air/fuel charge in the combustion chamber of the or each cylinder. The major part of the combustion chamber of each cylinder is afforded by a recess formed in the piston crown, and a catalytic element of mesh, grid, perforated or sintered or other construction, is carried by the piston in a position at least partly overlying the said recess, the fuel being injected into the said recess to contact and pass through the catalytic element, being ignited by its contact with the catalytic element.
Claims14
An internal combustion engine of reciprocating-piston type having a cylinder with a combustion chamber, and a piston with a crown in the cylinder, the major portion of the volume of said combustion chamber being afforded by a recess formed in the crown of the piston, the recess having a bottom, a catalytic element in the cylinder carried by the piston and mounted in a position overlying the bottom of said recess, and means for injecting fuel into said recess, when the piston is at about its top-dead-centre position, in a direction such that substantially the whole of the injected fuel will contact the surface of the catalytic element to initiate its combustion.
