Abstract
An internal combustion engine has a fuel injector located in a side wall of each cylinder, and a combustion chamber in each cylinder formed largely by a cavity recessed in the crown of the piston, to define substantial "squish" areas between the piston crown and a cylinder head which contains an ignition prechamber, situated opposite the fuel injector, communicating with a sparking plug, the fuel injector being arranged to direct at least one part of the fuel into a region adjacent the ignition prechamber which forms part of the volume of the combustion chamber.
