Hi,

Thanks for answering my questions(twice).

I asked in Post# 45 about where the heat from the 800 Deg air charge would be going and you replied in #46.

If I understand your words corectly "serious expansion" is going to reduce the temperature and it will be carried away from the engine by an exhaust pipe.

Isn't the whole puropse of heating up the air so much to enable greater pressure and more "power" to be extracted from it?

If it is going to be cooled by serious expansion to the point that the heat is not an issue isn't this going to reduce or negate the benefit of heating it up so much in the first place?

Just one more question.

How hot do you calculate the engine as a whole will get when it is in service and has been running for an hour or so?
