摘要： An internal combustion engine with a cylinder lubricating system is proposed; with the system it becomes possible to supply lube oil of required amount at required timing to each of lubricators, and normal supply of lube oil is possible even when malfunction occurs in some of the lubricators or magnetic valves, and further the timing and amount of lube oil supply can be adjusted even in engine operation in accordance with varying factors such as properties of lube oil, lube oil pressure, etc., resulting in a reduction of lube oil consumption.
Lubricating oil pressure-fed by a lubricating oil pump is accommodated in a common lube oil feeding section, the lubricating oil accumulated in said common lube oil feeding section is supplied to a plurality of lubricators (injectors) through oil passages connecting said common lube oil feeding section to said lubricators and injected to the inner surfaces of cylinders of the engine by said lubricators, a plurality of electromagnetic valves are provided for opening or closing the oil passages and the timing and period of opening of each of the valves are controlled independently so that lube oil is injected from the lubricators to spaces between piston rings once per one reciprocation of piston.
