Ya know a few weeks ago we went around about the variable valve timing, that essentially is a variable displacement method.
But....at the end of the day....all we are trying to cut out of the equation is the pumping losses, which on their worst day are costing us 4% efficiency. I came away thinking the variable valve timing was a pretty good solution.
60% of the energy losses in the engine are due to thermal losses. What can we do to even get 1/3 of that back? Pretty much double our mileage if you could.
