Abstract

PURPOSE: To supplement the pressure in a cylinder so as to prevent the increase of oil up in a cylinder, by slightly opening a valve of the cylinder being at a standstill during a part load operation only at the vicinity of the bottom dead center of a piston.
CONSTITUTION: A four cycle engine comprising a cam 8 enging with the end of rocker arm 5 during normal operation and a cam 7 engaging with the end of the rocker arm 5 during a part loak operation, said cams 7, 8 are respectively mounted on a cam shaft 2 in a line in the axial direction. The rocker arm 5 is pivotally mounted on a rocker shaft 6 so that it can move in the axial direction, said movement in the axial direction is done by an actuator 9 acted in accordance with the normal or partial loak operations of the engine. If the valve 3 is a suction valve, the position of the cam 7 is adjusted so that the valve 3 has maximum valve lift position before the point of crank angle 180°.
