  • Lubrication Of Internal Combustion Engines (AREA)

Abstract

PURPOSE: To reduce the slapping noise of a piston and to exactly lubricate without loss in a piston reciprocating type internal combustion engine by forcibly supplying lubricating oil between the piston and the wall surface of a cylinder and lubricating by separate oil system from other portions.
CONSTITUTION: Lubricating oil inlets 19, 20 are opened at the wall surface of a cylinder 3, and independently communicate with lubricating oil storage section 26 provided at the bottom of a crankcase 5 via lubricating oil supply passages 24, 25 by oil pumps 22, 23, respectively. The pump 22 is driven by an air intake cam 13, while the pump 23 is driven by an air exhaust cam 14. Accordingly, the pump 22 discharges the oil in the vicinity of the bottom dead point of 180° of a cranking angle at the oil supplying timing, and the pump 23 discharges the oil in the vicinity of the bottom dead point of 540° of the cranking angle. Thus, an oil film is formed between the skirt portion 4a of the piston and the wall surface of the cylinder 3 to reduce the slapping noise of the piston.
