multi point fuel injection
1)The carburettor is basically a quantity governing system for the icengine. MPFI on the other hand is a quality governing system.
2) MPFI can increase power output as injector resides very close to the Intake valve, and can be programmed to vary injection pulse in terms of pressure, duration etc.
3) MPFI eliminates the vapor inconsistencies that exist in a normal intake manifold, and each cylinder recieves the exact calculated amounts of fuel in highly atomised spray.
4) Engine sluggishness is reduced as response is almost instantaneous.
