Title:
TEMPERATURE CONTROLLER OF LUBRICATING OIL FOR ENGINE
Document Type and Number:
Japanese Patent JPS6053608
Kind Code:
A
Abstract:
PURPOSE:To keep viscosity in lubricating oil optimum, by installing a heating device or a cooling device and also a device controlling a lubricating oil flow rate in a bypass pipe line all in the bypass pipe line of the lubricating oil, in case of an engine for automobiles. CONSTITUTION:Insides an oil pan 3, there are provided with an oil filter 4 and an oil pump 5, feeding lubricating oil to every engine part by way of a pipe 52, while it is branched to pipes 55 and 56 via a check valve 51 and these pipes are connected to a heating device H inside an exhaust manifold 2 via a cooling device C and a solenoid valve B being set up inside a radiator through a solenoid valve A. A control unit 7 constituted of a microcomputer or the like inputs a signal out of a temperature sensor 6 at the bottom part of the oil pan 3 via an A/D converter 8. And, a control signal is outputted from an output circuit 10, controlling these solenoid valves A and B, and lubricating oil temperature is controlled within the specified range.
