But I thought the denser cold air also had more oxygen per cc so it equaled a bigger Ka-Pow at each detonation.
Dunno though. I used to know, but I forgot.
If the engine got more oxygen, it would be capable of producing more power. The fuel injection system would adjust. But the human computer in your head compensates and opens the throttle only as needed to maintain the speed you want, and thus the amount of power produced and fuel consumed would not change at a steady speed. The denser air would require more power too push through, thereby increasing fuel consumption.
