Modification of piston skirt design

Piston skirt wear is one of the main failure mechanisms affecting the life of automotive engines. Wear occur during operation because insufficient of lubricant oil in cylinder, over heat, connecting-rod non-alignment and other possible cause. At higher temperature the friction will increase because...
