<P>PROBLEM TO BE SOLVED: To provide a lubricating oil supply device of a vehicle engine, which will not cause lubrication shortage in the engine, when the vehicle stops by idling stop operation. <P>SOLUTION: A bypass switching valve 38 is arranged for bypassing an oil temperature switching valve 40 for switching the inflow of lubricating oil to an oil cooler 42 by the temperature of the lubricating oil when a deceleration request is made to a vehicle. Thus, when an idling stop is performed in succession to the deceleration request, the lubricating oil is made to flow in the oil cooler 42. Thus, before stopping the vehicle by the idling stop, the temperature of engine oil 25 is lowered, sticking performance is improved, and an oil film shortage can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
