摘要：
Disclosed is an oil heating apparatus for an internal combustion engine, in which a heating unit for heating an oil is arranged adjacent to an oil pump on an oil path which extends from an oil pan to the oil pump of the internal combustion engine and allows the oil to pass therethrough, and energization of the heating unit is controlled by a heating control unit. When an oil having a high viscosity due to a low temperature is heated to increase the viscosity thereof, the load on the oil pump is reduced to allow an easy starting operation of the internal combustion engine at a low temperature.
