Abstract (en)
[origin: JPH01313614A] PURPOSE: To cool high temperature engine parts sufficiently by branching a secondary circuit from a lubricating oil circuit of the downstream side of an oil cooler to form an additional cooling circuit. CONSTITUTION: A lubricating oil circuit 2 and a cooling oil circuit are connected to a common oil sump 7. A secondary circuit 10 is branched from the lubricating oil circuit 2 of the downstream side of an oil cooler 8. An injection nozzle 12 for cooling a valve flange of a cylinder head is arranged in an outer pipe 10a of the secondary circuit 10. An injection nozzle 12 for cooling a piston is arranged in an inner pipe 10b. In this way, it is possible to cool high temperature engine parts sufficiently.
