PISTON FOR INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE USING THE PISTON
摘要
A piston top surface (23) has a depression. A center region (28A) is formed at the center of the depression to secure the diameter of a center tumble flow to be large. A side region (28B) is formed on both sides of the piston top surface to generate a side tumble flow that is not influenced by a cylinder bore inner wall and has a flow line generally parallel to that of the center tumble flow.
