摘要:
A piston capable of reducing the frictional resistance between skirt portion and a cylinder inner surface and improving fuel efficiency is provided. The invention is a piston for an internal combustion engine wherein when the piston slides along a cylinder inner surface, a high surface pressure portion occurs at a center of each skirt portion and low surface pressure portions occur at both sides of the high surface pressure portion. The high surface pressure portion of plural portions is provided with a horizontal groove. The low surface pressure portions of the plural portions are provided with an inclined groove that is inclined downward toward the high surface pressure portion and that is connected to an end portion of the horizontal groove.
