I saw this Engineering Explained video a while ago: https:/
The guy says that a small 4 cylinder engine will require about 7 seconds worth of gas while idling, to start that engine. His point was that if you have to stop for more than 7 seconds, it would save fuel simply to cut off the engine.
I had a civic with a 4 cylinder 1.6 liter engine. Now, my cars have a 6--cylinder, 3.3L engine.
I'm wondering how much gas would be required to start these engines, compared to idling time. Would it still be about 7 seconds? Would it be about 14 (assuming an engine twice as large, would require that much more gas to start)? www.youtube.com/ watch?v=dFImHhNwbJo
