    Untrue for diesel EGTs where a very rich mixture will in fact cause high temps as it will still be doing some burning while it’s out of the cylinder already.

      Wrong. No oxygen is left so it can’t burn. It exits the exhaust as unburnt fuel exactly as you stated in your original comment.

      Extra fuel in a diesel cycle is used as coolant just like in any of the gas cycles. Gas is see through when it vaporizes, diesel isn’t. A turboed gas engine rolls coal too but it only smells bad if it lacks emissions systems.
