ABSTRACT:
A lubricating apparatus for an internal-combustion engine comprises a detector for detecting whether the engine runs or not, a heat storage reservoir connected to lubricating oil outflow and inflow ports of the engine by a circular pipe system for storing the oil and maintaining its temperature, the heat storage reservoir being provided outside the engine, a hydraulic pump provided between the inflow port and the heat storage reservoir for controlling the supply of the oil stored in the heat storage reservoir to portions of the engine in response to a control signal, and a controller responsive to an output of the detector for producing the control signal to stop the hydraulic pump in order to maintain a temperature of the oil stored in the heat storage reservoir when the detector detects a stop of the engine and for producing the control signal to actuate the hydraulic pump to supply the oil, whose temperature is maintained by the heat storage reservoir, to the portions of the engine. The restarting of the engine is easily made because the oil is collected in the heat storage reservoir when the engine is stopped. In addition, the size of the engine is decreased, because the oil pan is omitted or part of the oil pan remains in the engine.
