"Mpfi’ stands for 'multi point (electronic) fuel injection'. This system injects fuel into individual cylinders, based on commands from the ‘on board engine management system computer’ – popularly known as the Engine Control Unit/ECU. Mpfi Systems can either be : a) ‘Sequential’ i.e direct injection into individual cylinders against their suction strokes, or b) ‘Simultaneous’ i.e together for all the four or whatever the number of cylinders, or c) ‘Group’ i.e into Cylinder-Pairs. These techniques result not only in better ‘power balance’ amongst the cylinders but also in higher output from each one of them, along with faster throttle response. Of these variants of Mpfi, 'Sequential' is the best from the above considerations of power balance/output."

Most all gas engines are similar in operation. The MPFI is just one method of delivering the fuel to the cylinders. It would be to complicated to cover how it and others work here. MPFI is a very good system.

MPFI stands for multi-port fuel injection. An engine with MPFI will have a fuel injector at the intake port for each cylinder. Other possible setups are throttle body injection (injectors and throttle in one assembly) and carburetors.
