Abstract

The diesel engine has a crankcase (1) piston (2) and crankshaft (3). The cylinder head (4) has inlet (10) and outlet (11) values and a separate combustion chamber (8). The combustion chamber (8) communicates with the accumulation chamber (9) through the orifice (14) which is partially obstructed by the hydraulic cylinder (13). Thhe combustion chamber (8) be shut off from the compression chamber (5) by the value (12). This value (12) is actuated by hydraulic pressure acting on a piston inside the cylinder (13). The value (12) opens before top dead centre of the compression stroke and then closes after ignition during the expansion. The timing of the opening and closing of the value can be altered depending on whether the engine is being supercharged or not.
