What is MPFI System

MPFI means Multi Point Fuel Injection system. In this system each cylinder has number of  injectors to supply or spray fuel in the cylinders as compared to one injector located centrally to supply or spray fuel in case of single point injection system.

The advantages are like there will be more uniform A/F mixture which will be supplied to each cylinder, hence the difference in power developed in each cylinder is minimum. Vibration from the engine equipped with this system is less, due to this the life of engine components is improved. then there is no need to crank the engine twice or thrice in case of cold starting as happens in the carburetor, Immediate response, in case of sudden acceleration / deceleration.  Since the engine is controlled by ECM, more accurate amount of A/F mixture will be supplied and as a result complete combustion will take place. This leads to effective utilization of fuel supplied and hence low emission level. And with all this the mileage of the vehicle will be improved.
