What is meant by big bang engine?
Each connecting rod fires 90ยบ 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.
