Abstract

The invention discloses an energy-saving and environmentally-friendly piston of an internal combustion engine. The piston is that a vertical groove which passes through the whole skirt part is axially formed in the surface of a piston skirt; lubricating oil and grinding chippings can be stored in the groove; lubricating oil can be fully supplied to the piston while moving in a cylinder sleeve by reciprocating, the lubricating oil can be uniformly distributed, so that the frictional heat can be dispersed, the lubricating effect can be improved, the frictional resistance can be reduced, the cylinder can be prevented from pulling and knocking, and as a result, the service lives of the piston and a cylinder can be prolonged; the groove and the piston move in the same direction; the piston skirt part is arranged by a passing manner, so that the piston can be uniformly stressed during moving; meanwhile, stress concentrated at an oil returning hole in a third ring groove of the piston can be unloaded through the groove, and thus the fatigue life of the piston can be prolonged.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly internal combustion engine piston based on drag reduction and wear resistance, which can be applied to various internal combustion engines such as gasoline engines and diesel engines. Background technique [0002] Automobiles have become an indispensable means of walking, transportation and transportation in people's daily life. Under the current global background of energy saving, emission reduction, haze control and anti-pollution, the development and promotion of new energy vehicles has become the top priority, but the imperfect supporting facilities and high prices make it take 8 to 10 years to complete popularization. The internal combustion engine is the power source of automobiles and the main source of harmful exhaust emissions from automobiles. Many studies have proved that 10% to 20% of the combustion energy of internal combustion engines is consumed in mechanical losses, and...
