One of those changes was the evolution of the cylinder firing order from the well-known to As the crankshaft rotates, the paired pistons will simultaneously arrive at top dead center TDC. One piston will be at the top of the compression stroke, and the other will be at the start of the intake stroke. After the crankshaft spins degrees from this position one-half of a complete engine rotation cycle , the order of those two cylinders will trade off. Swapping the firing order between any of the paired pistons can be done within reason but requires a special camshaft to change the order of valve actuation; this will also change the overall engine firing order, including the ignition order. Additionally, paired pistons firing order sequences will always be degrees from each other.
