We're talking about 'throttle control', where the carburetor, injectors maintain a specific amount of fuel/air to the pistons and depending on the load on the engine (going up or downhill), the rpms decrease or increase.
On my Terramite tractor, I have a knob on the dash that I can pull out which increases the rpm, I give it a slight twist and it 'locks' in place. It takes the place of an accelerator pedal. Airplanes have throttle control, you've all see pictures of the pilots hand advancing the throttle and it stays in the position that he put it in. I would love one for my Insight. Insights have lean burn where the best mpg is. At 50+ mph, when the engine conditions are right, it will go into lean burn where the air to fuel ratio is something like 22:1 and the mpg jumps from 60 to 75+. It is a pretty delicate sweet spot, if you move the position of the gas pedal even the tiniest bit, it can go out of lean burn, or if the load on the engine (going up a hill or slight incline) is too much, then it gets kicked out. But if you're careful and on a flat stretch of road, you can ride for miles and miles at 75+ mpg.
