Lubrication is whollyfilteredandpressurizedlubrication systembytrochoidtype oil pump. From the maingallery in the crankcase the pressurized oil runs through the crank journals and crankpins, and from the larger part of the rod the oil is supplied in the form of splash to the parts neces- sary to be lubricated, while part of the oil also runs through thebearingsofcamshaft to lubricatebothintakeandex- haust cams, and tappets. Ths system includes the governor gears and it is installed in the crankcase.
