EGT's & CHT's

[Guest J430]

I have watched many of you talking on various threads about EGT and CHT in Jabs and its interesting to see what engines really do.

 

I have "borrowed" this data from a friend who is running in a brand new IO550 in a C210 so while the engine type etc is not a Jab or similar, the interesting thing is the temps at 50 deg ROP.

 

By Sunday afternoon after I have been in the thing myself and he gets a good long cruise out of it it will be interesting to fiddle and monitor. May have to video it.

 

Anyway have a look at these.................

running in a new IO550 installed in a C210N.The aircraft is fitted with an EDM800 all cylinder - without which I would not have any reason to ask this question regarding EGT/CHT temperatures.

 

The EGT/CHT temps for the 6 cylinders, taken at 50oC ROP are as follows:

 

1 - 740/173C = 1364/343F

 

2 - 758/174C = 1396/345F

 

3 - 768/179C = 1414/354F

 

4 - 770/176C = 1418/349F

 

5 - 723/194C = 1333/381F

 

6 - 741/183C = 1366/361F

 

These temps are for about 70% power (25/24) at 5000', OAT 18oC with the cowl flaps open.
