PURPOSE:To suppress the occurrence of wear to a minimum, by a method wherein a lubricating amount drive shaft is driven synchronously with the number of revolutions of an engine, and a lubrication timing and an effective stroke are properly controlled by means of an engine load and an cylinder oil temperature. CONSTITUTION:A computer 103 of a control device 100 inputs signals from a crank angle detector 8, a number of revolutions of engine detector 9, and a cylinder oil temperature detector 11. Synchronous rotation is effected at the number of revolutions of a cam drive shaft 3 of a lubricator 21 being integer-fold or one integer-ths as large as that of an engine 1 through a number of revolutions phase setter 105, a corrector 108, a number of revolutions phase regulator 5, a number of revolutions detector 7, and a phase detector 10 to drive a plunger. The effective stroke of a plunger and a lubrication timing are controlled by means of the angle of rotation of a handle 2, i.e., rotation of an eccentric shaft, according to an engine load and a cylinder oil temperature through an angle of rotation setter 104, corrector 107, an angle of rotation regulator 4, and an angle of rotation detector 6. This constitution enables minimization of wear of a piston ring and a cylinder liner.
