ABSTRACT:
To enhance productivity and maintainability of an internal combustion engine for a vehicle with a torque converter. An internal combustion engine with a torque converter includes a single feed pump for supplying both a working oil for a torque converter and a lubricating oil for the engine with an oil filter in communication with a discharge port of the feed pump being fitted to a crankcase cover. An outlet oil passage of the oil filter is branched into a low-pressure oil passage provided with an orifice and an oil passage for supplying a high-pressure control oil to changeover valves of a transmission. The high-pressure oil passage is provided concentratedly in the crankcase cover.
