Anybody know a real rough estimate or calculation from an engine book on how many btu/hr are introduced to engine oil based on rpm? I may just make something up, but we are trying to figure this out for a project for class.

Just going from memory, try JR's value for HP --> Btu/hr and assume that the coolant losses (including oil) are about equal to the actual engine power output at the flywheel. Now, assume the oil only takes maybe 30% of the heat away and the radiator coolant takes the other approx. 70% away.
It's a starting point, but these are all VERY rough numbers. They can change rapidly based on engine rpm, CR, fluid temps, etc. |
