Abstract

The engine is of the reciprocating type with a conventional cylinder (1) and piston (2). The cylinder head is modified to take a combustion chamber (5). The combustion chamber is closed off by a poppet valve (9) which is operated through a cam (16) and return spring (15). There is a spark plug (18) in the combustion chamber. There is a spark plug (18) in the combustion chamber. The engine operates by drawing in the air and gas mixture into the cylinder. On the compression stroke the valve (9) opens and allows the compressed gas to enter the chamber. The cycle is repeated and one or more further charges are compressed into the combustion chamber. When the charge is sufficiently high, a spark ignites it and the gases enter the cylinder through the valve (9).
