With super heat engines you are going to produce quite a bit of waste heat. That's all there is to it.

The problem with gas engines is their thermodynamic cycle. You have isobaric intake losses right away on the start of your cycle. Then with heat addition you are using constant volume heat addition. In theory you add all the heat at top dead center, but we know that doesn't happen.
In theory a gasoline engine can only be a maximum of about 50% efficient.
Institutions have spent millions of dollars trying to achieve this and still the closest they can get in the lab doesn't really get close to maximum theoretical efficiency.

If you think you can best the lot of them I say go for it.
