Abstract

PURPOSE:To reduce the slap noise of a diesel engine or the like, by ejecting lubricating oil to the inside surface of the cylinder through an ejection port only for a prescribed period during which there is a possibility of swinging. CONSTITUTION:A connecting rod 14 swings about a wrist pin 11 as a fulcrum. A second oil hole 17 and a second oil passage 15 are made coincident with each other only at a prescribed point in time. At every time of the coincidence between the hole 17 and the passage 15, lubricating oil in the passage 15 is supplied to an oil ejection port 6 through the oil hole 17, an oil chamber 13, a first oil hole 16 and a first oil passage 9 and ejected to the inside surface 3 of the cylinder. The ejection of the oil is effected only at the prescribed point in time or for a prescribed period of time, at or during which the piston 1 is likely to swing. The prescirbed point in time is set by adjusting the position of the hole 7. The prescribed period of time is set by adjusting the width of the hole 15.
