Would you believe that in measuring the temperature at the 7 o'clock
location and comparing it to the 2 o'clock location on a cylinder that the
temperature of the cylinder head can vary as much as 150 degrees F from
one loctation on a cylinder to another on the SAME cylinder???
What does that do to your engine? It makes the cylinders go out-of-round at
high temperatures. Not a good result
George,
We also know (in tractor configuration) that the forward cylinder on one side of the engine has the hot exhaust part of the head directly in the breeze whilst its the cooler induction part on the other side. Sophisticated dickering with the cooling plenum aside, this is precisely why the next advance in internal combustion engines for aircraft will come with liquid cooling and the consequential tighter tolerances and greater efficiency.
