Piston for an internal combustion engine |
摘要 |
A piston for an internal combustion engine is provided. The engine has an intake port through which an intake air is introduced into the cylinder in a way as to produce a swirl that travels along while whirling about an axis transversal to an axis of the cylinder. The piston has at a crown face thereof a cavity that has a part-cylindrical bottom. The cavity has a longitudinal center axis extending obliquely to a crank axis so that the longitudinal center axis of the cavity nearly coincides with an axis along which the swirl travels within the cylinder.
