ABSTRACT:
A diesel engine (10) has a pre-combustion chamber (30) with an angled and tapered transfer passage (60) leading to the main combustion chamber (44). The transfer passage (60) is tapered to provide a larger lower end (62) facing the main chamber (44) and smaller upper end (64) facing the pre-combustion chamber (30). Air passing through the passage (60) during the compression stroke undergoes heating and swirling within the pre-combustion chamber. The piston has an upper surface (46) with recessed lobes (20) and (22) and recessed passage area (28). Each recessed lobe functions as a valve pocket for the respective intake valve (32) and exhaust valve (42). The valve pockets are deep enough to provide sufficient valve lifts to allow valve overlap periods comparable with spark ignition gasoline engines without interfering with the piston upper surface (46).
