Problems solved by technology

[0002] At present, for engines with large cylinder diameters and high strokes, the pistons and connecting rods mostly adopt forced cooling and lubrication, and one of the forced cooling and lubrication methods is to cool and lubricate the pistons by opening oil passages on the connecting rod body and delivering oil to the pistons. However, due to the limitation of the oil pressure provided by the oil pump, the amount of oil to the piston and connecting rod is not sufficient, so that the cooling and lubrication of the piston and connecting rod of the engine with large bore and high stroke cannot be guaranteed, which seriously affects the overall performance of the engine and threatens the engine. reliability
