Internal Combustion Engine With Cylinder Lubricating System.

Abstract: An internal combustion engine having a plurality of lubricators attached to one cylinder for supplying lube oil in the common lube oil feeding section to the inner surface of the cylinder, wherein are provided a plurality of electromagnetic valves for opening or closing oil passages connecting to the lubricators independently; lube oil supply pressure detectors for detecting the lube oil supply pressure of each of the lubricators; and a controller which controls the timing and period of opening of each of said electromagnetic valves in accordance with loads and rotation speeds of the engine, compares the detected lube oil supply pressure of each of the lubricators with a permissible value of lube oil supply pressure, and judges that abnormality has occurred in lube oil supply when the detected lube oil supply pressure exceeds the permissible value.
