Abstract
An oil supply system for an engine is provided, which includes an oil pressure controller for controlling a variable displacement oil pump to adjust a discharge pressure thereof to reach a target oil pressure corresponding to an operating state of the engine, the variable displacement oil pump capable of adjusting a discharge amount of oil, a load detector for detecting an engine load, and an oil temperature detector for detecting an oil temperature. When the engine load is low, to increase an amount of oil mist flowing inside a crank case of the engine, the oil pressure controller controls the variable displacement oil pump to increase the discharge amount as the oil temperature becomes lower, the oil mist generated by the oil flowing out of a bearing part rotatably supporting at least a crankshaft and being atomized, the engine load being considered low when below a predetermined reference load.
