The engine has a cylinder with a combustion chamber (1) which has a central ignition plug (17) and an offset fuel injector (16). The top of the combustion chamber is formed by a section of the cylinder head (4) with a surface which slopes down in two directions from a centre line (12) which separates its inlet (7,8) and outlet (9,10) ports. The injector (16) enters the combustion chamber on the centre line (12), and the reciprocating piston (3) has an off-centre cavity (15), e.g. hemispherical in shape, in its upper face, situated beneath the injector and ignition plug. A variant of the design has two cavities, lenticular in shape, for the ignition plug and injector. |
