Perkin Generator Question

Lack of cooling or your misunderstanding of the normal operating conditions for this turbocharger. Contact Perkins to see if this is normal, it might just be normal for the load your application.

Did you ever consider that maybe it's normal.

Or, maybe the designers just like red.

Maybe, just maybe, the Perkins people can tell you why, if only you'd use the telephone and call them and ASK them.

These are the possible reasons

1. injection pump needs calibration
2. injection and valve timing needed to be corrected or synchronized as well as valve and cam clearances to be tuned up
3. if its intercooled or supercharged, see that intake air cooling device works
4. Check that engine coolant circuit and temperatures is normal, if so
   , the problem is simply fuel which is not burn completely at the combustion chamber due to 1&2 and high RPM still burn at the exhaust manifold, so back to 1&2 or perhaps engine needed to be microchip metered at high RPM fuel should be adjusted to enough quantity in order to burn just completely or may be there are solutions to this problem. (its a good research topic by the way, solutions to burn fuel completely at some microsecond time or at high speed) for gasoline, the less likely this would happen
