Ken,

I wrote my response before I read your response. It is interesting how we picked up on different things.

I didn't put together the idea HHO is supposed to oxidize anything. I agree with you - HHO is unicorn farts.

And I agree with you Ken there are not many opportunities for incremental improvements in playing with a modern fuel injection system.

But I think there are quantum jumps available - throwing away a paradigm, and getting out side the box.

So. back to the throttleing discussion.

Lets say we take a multi port fuel injection engine.

And we take the throttle body and wire it wide open.

Then we tell the computer to read a fly by wire throttle plate. And we shut off the injectors 98 percent of the time, but every once in a while we give a specific cylinder the "right" amount of fuel to run at WOT.

But most of the time the cylinders are not getting any fuel.

Then we determine "once in a while" to be decided by the throttle pedal - the more we push on the throttle, the more often a cylinder gets a shot of gasoline.

No pumping losses. Full efficiency of the cylinder. The engine can run at very efficient loads, and we can use the air pumping through the engine to be a pseudo carnot cycle.
