2 Cyl engine?
I appologize if this isn't the right spot for this, but I got to thinking about car engines the other day.
They have those vehicles with 8 cyl that shut off cylinders and run on 4 at highway speeds.
Well, I was thinking, even in rural areas, you spend a decent amount of time within village limits where the speed limit is often below 40mph and acceleration isn't all that important, but if you want to stay alive, I don't think a 2 cyl would work on the highway.
So, I wonder if it is possible to build a 4 cylinder engine that could be manually switched from 2 cyl or 4 cyl. I know I got a 4 cyl vehicle that gets decent highway mpg, but it burns gas accelerating. I know I can't build an engine myself, but I just theorize that for a small car, this could be good.
Another idea not related is to have the battery power the engine fan, not the engine like in cars I saw in the early 90's, except to have a switch to turn them off (when the car will just sit there or when you are working on it.)
