Hi sir my name is ali I am mailing you to ask one technical question there are two ways to increae power of engine one is to increase the size cubic capacity cc (cylinder size)of the engine and second is to increase number of cylinders there are 6.0 litre v8 and there is 6.0 litre v12 which got more power and what the main different between v12 and v8 when both engines have same 6.0 litre dispalcement well waiting for your reply thanks indeed

While the displacement is the same, you get more power pulses per revolution so that power is more steady. With a V8 engine you get a pulse of power, then a lull or gap where nothing takes place. Finally you get another power pulse from a second cylinder, then another gap. You get four of those power pulses per crankshaft revolution. With a V12 engine, the power pulses are smaller, but you get six of them per crankshaft revolution so the gaps in between are smaller.

Think of pedaling a bicycle. You have two feet and you get two power pulses per revolution. Now imagine you have a two-seater bicycle and the other person's pedals are staggered compared to yours. You'd get four power pulses per revolution. If two kids were pedaling that bicycle, they would have smaller power pulses but more of them. Together they could pedal up the side of a building while you by yourself could only pedal up a steep hill!
