Abstract

PURPOSE: To prevent noise by opening an oil pouring port in the vicinity of the bottom deal point outside the piston ring sliding range on the cylinder inner wall and arranging an oil guiding groove on the periphery of the piston skirt part, permitting the pouring of lubricating oil also at the position in the vicinity of the top deal point.
CONSTITUTION: On the inner surface of a cylinder 3, an oil pouring port 10 is opened at the position opposite to the peripheral surface of the skirt part 4a at the position of the bottom dead point outside the range of sliding of a piston ring 8 in relation to the direction of sliding of a piston 4. Said oil pouring port 10 communicates to the annular oil groove 12 formed on the joint surface between a cylinder block 1 and a crank case 11 and communicates to an oil pump 15 through an oil passage 13. Moreover, on the peripheral surface of the piston skirt part 4a opposite to the pouring port 10, an oil guiding groove 14 is arranged which extends in parallel to the direction of sliding. Thus, a high pressure oil membrane is formed in the clearance at the position of the top dead point of the piston 4, and the noise due to piston slap can be reduced.
