“I’ve been trying to think how to capture radiator losses for over 30
years,” explains the veteran camshaft grinder and race engine builder.

knew immediately that I had the answer.”

Basically, his engine injects water into the cylinder after the
normal exhaust strike, which adds another steam power stroke and
exhaust stroke, as well as cooling the cylinder. This apparently
eliminates the need for an external cooling system and uses some of
the heat energy that would otherwise be lost through the radiator.

Thoughts? Would this present a corrosion issue? Does it sound
worthwhile?

But then, if you cool the cylinder down, doesn't the next cycle lose
efficiency in the gasoline portion of the cycle?


I'm going to guess that it depends on the heat.

How hot the cylinder is - and how much heat is removed.

There is probably a peak temperature at which things are most efficient.
Above that (or below it) efficiency would be less.

Auto engines have water jackets and radiators to remove excess heat.
Without them the engine would overheat and fail.

If this trick can make the engine work right at the right temperature
the engine might not need (as much?) external cooling.

SWAG, that's all.
