Abstract
The method comprises spraying at higher loads a fuel jet (17) through an ignition chamber (9) and a connecting passage (10) onto the wall (18) of a combustion chamber (4), where it spreads as a thin film (19). The air flow in the ignition chamber (9) during the compression stroke of the piston (2) and control of fuel injection is such as to cause individual fuel particles to be separated from the fuel jet (17) to form an ignitable mixture with the air and residual gas remaining in the ignition chamber (9). This ignitable mixture is ignited in the ignition chamber (9) so that a flame penetrates through the connecting passage (10) into the combustion chamber (4) to ignite the fuel evaporating from the combustion chamber wall (18). At idling and lower loads the injector provides an atomised spray (20) and an igniter provides for starting. <IMAGE>
