    Not that I'm going to try this but what about using the fuel as coolant for the engine then injecting this scavenged energy through the injectors.

    Don't know if being pressurized would get over the flash point problem, if it was a problem.
    I know cooling fuel adds power but heating it adds more if done correctly.

    Is the fuel flow sufficient to cool the engine?

    Thumbs down

    No, the coolant flow greatly exceeds the fuel flow, so cooling the motor with fuel before consuming the warm fuel is not practical. Second cool fuel works best for 2 strokes. Cooled fuel entering the crankcase can cool the crankcase enough to lower the air pressure there and cause greater pressure drop across the throttle plate. This is the same as a 1/2 to 1 psi supercharger.
