Abstract
Apparatus is disclosed for lubrication of the operating components of an internal combustion engine with accelerated heating of the lubricant during engine warmup, comprising (i) a primary circuit for lubricant recirculation including a primary reservoir adapted to receive lubricant drainage from the engine and a primary conduit adapted to return lubricant to the engine, (ii) means for pumping lubricant through the primary conduit to the engine, (iii) means for preheating the lubricant with heat produced by the engine employing a heat exchanger along the primary conduit, and (iv) an auxiliary lubricant reservoir and a return conduit providing fluid communication for the flow of lubricant from the auxiliary reservoir to the primary reservoir. A valve in the return line is controlled to permit flow of lubricant to the primary reservoir in response to a drop in the primary reservoir lubricant level. Means are provided for selectively diverting lubricant from the primary circuit to the auxiliary reservoir following engine warmup when the temperature of the lubricant in the primary circuit reaches a preselected operating temperature.
