Asnwer:MPFI stands for Multi Port Fuel Injection. As opposed to TBI, Throttle Body Injection. A cam and crank sensor tell the engine controller which cylinder's injector to fire and for how long. They fire with the same time as the spark plugs do. This is a more fuel efficient way to gain power. The TBI system has one or more injectors that spray fuel into the throttle body and the mixture is drawn into the engine all at once. The MPFI system has one injector per cylinder and only sprays on the compression stroke. Answer:mpfi in automobile engine is an system used in diesel engines to spray diesel at a higher speed so as to ignite the charge of air which is compressed at a higher temprature in this there are diferrent injectors on each cylinder head to give higher efficency of fuel burning this is mpfi system in automobile engines.

Will a 3.1 multiport f1 engine work in a 1996 buick century It currently has a 3100 engine in it?

The 3100 SFI engines were rated to 160HP, like the 3300 engines were. The 3.1 MultiPort FI were rated at 140HP. Of course, you certainly can swap a 3.1 MPFI engine in your Century, and in my opinion, you would do a very good choice. If a 3.1 MPFI can work in a Chevrolet Cavalier, why wouldn't it work in a Century?

What is an mpfi engine?

'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.
