Abstract (en)
[origin: EP0953735A1] Lubricating oil is pumped (12) from a sump (3) to a cylinder block (1) and a cylinder head (2) through heat exchangers (5,6) which are also traversed by engine cooling liquid (9). For a range of sump oil temperatures heat exchanger valves (7A,7B) and (8A,8B) are operated such as to either pass cooling liquid through particular exchangers or not and thus optimize oil protection of the engine for a range of operating conditions
