| 摘要 |
A diesel engine (10) has a precombustion chamber (30) with four circumferentially spaced and angled transfer passages (60, 61) leading to the main combustion chamber (44). Each transfer passage (60, 61) is tapered to provide a larger lower end (62) facing the main chamber (44) and smaller upper end (64) facing the precombustion chamber (30). Air passing through the passages during the compression stroke undergoes heating and swirling within the precombustion chamber. The flame plumes passing from the precombustion chamber to the main combustion chamber are aimed toward the centers (68) and (69) of respective recessed lobes (20) and (22) within piston (18).
