Oil Temp Vs Engine RPM
Hi all pprune members,
I have notice that most of the time when jet engine has raised their RPM
, the engine oil temperature will decrease regardless of flight condition. But
when I look in piston engine like Cessna 172, the oil temp rise as the engine RPM
increase. Why is that happened? Is it due to the fact that the jet engine has an
oil cooler that cool by the fuel and hence more throttle open = more fuel flow
through the oil cooler and hence the oil temp drop is that right or it has the
other thing to do with it? I have tried to search in this forum but have no luck
so far.
Thanks for all of your reply.
Best regards.
