Two days back my friend made a seminar in my class on "big bang engine" but I am not able to catch the real point in it.He said that big bang engine is a engine which has a firing order not in a specific interval but will have successive close firing order which will give a better power usage. It will help in initial pickup of engine and this engine is used in yamaha YZF R1. Is this really the sole purpose of big bang engine and if possible give a briel on big bang engine with firing order?

All I know is Yamaha R1 2008 has the Big Bang engine. Maybe @#-Link-Snipped-# and @#-Link-Snipped-# can talk a bit about this?

The important bit is that each connecting rod is 90 degrees from the previous one. Its motogp tech coming to street bikes for the first time. It increases usable power which also helps traction.

Each connecting rod fires 90º from the next, that means the cylinders fire at 270°- 180°- 90°- 180°. The power pulses spread out to the rear tire which allows to regain traction in between each pulse. More usable traction under large throttle openings can be achieved. It is possible to accelerate out of corner earlier and harder. This firing order will be called as big bang firing order. Engine sounds will be high in these type of engines.
