I think it was Ford that determined if they shut off a cylinder injector every other firing, the engine could continue to run without radiator water to limp home. So it might have some effect by allowing a grill block and reducing the heat losses in the engine.

I still think this idea has merit on a gasoline engine. Do a misfire by skipping gasoline on one rotation.

In order to maintain same power, you would have to have MORE air, so you would open the throttle more.

Hence, less pumping losses.

This is basically pulse and glide thousands of time per minute.
