Multi-port injection (MPI) is a fuel delivery system used in internal combustion engines where fuel is injected directly into the intake manifold, specifically near each intake valve. This allows for better atomization and mixing of fuel with air, improving combustion efficiency and engine performance. MPI systems typically provide better throttle response and lower emissions compared to older single-point injection systems. Additionally, they can help optimize fuel distribution across all cylinders, enhancing overall engine output.

What is a MPI?
MPI stands for multiport injection.
What type of fuel system does a 2001 dodge neon have?
Multiport fuel injection.
Where is the carburetor located on a 1993 Bonneville SE?
It doesn't have a carburator. It is fuel injected.AnswerNo carb, just multiport fuel injection.
Which chevy's use multi port fuel injection on the 350 engine?
The late 80's to early 90's tuned port engines had multiport injection, along with the lt1, and the later ls1.
Where is the crank position sensor located on a 1991 dodge Dakota 3.9 6 cylinder 2wd don't tell me its on top of the motor by the bellhousing on the right hand side its not?
On a 1991 with t-body fuel injection, there isn't a crankshaft position sensor. There is only the pick-up plate in the distributor.The ckp in the bell housing is only on the later multiport fuel injection system.On a 1991 with t-body fuel injection, there isn't a crankshaft position sensor.

Where are the fuel injectors located on a 1991 Honda Civic hatchback?
If this is a multiport injection system they will be located along a fuel rail going into the intake manifold. If it is a Throttle Body Injection then it/they will be at the throttle body intake. Hope this helps.
Fuel pressure 1996 Chevy 1500 4.3L?
There is 3 types of fuel injection TBI (Throttle Body Injection One Injector) 9 to 13 PSI CMFI (Central Multiport Fuel Injection) 58 to 64 PSI CSEFI (Central Sequential Electronic Fuel Injection) 55 to 61 PSI
What is an mfi fuel system?
MFI is an acronym for Multiport Fuel Injection. An MFI Fuel System is a fuel injection system that uses one injector per cylinder, mounted on the engine to spray fuel near the intake valve are or the combustion chamber.
What year is a Geo Metro multi port fuel injected?
For the Geo Metro, multiport fuel injection was introduced in 1998, replacing TBI. This car was in production from 1989 to 2001.
Fuel pressure for 1998 sonoma?
Throttle Body Injection (TBI) Aprox. 9 - 13 psi with key on, not running and a 3 -10 psi drop when running at idle. Multiport Fuel Injection (MFI) Aprox. 41 -47 psi with key on, not running and a 3 -10 psi drop when running at idle. Central Multiport Fuel Injection (CMFI) Aprox. 58 -64 psi with key on, not running and a 3 -10 psi drop running at idle. Central Sequential Electronic Fuel Injection (CSEFI) Aprox. 55 -61 psi with key on, not running and again the 3 -10 psi drop running at idle.
Where is the coolant temperature sensor located on a 1994 Chevy Astro Van?
Its on the front of the engine, next to the thermostat housing. On a TBI (throttle body injection, engine code Z) motor, it points straight up, on a MFI (multiport injection, engine code W) motor it points forward.
What is the firing order for a 1990 Pontiac Transport 3.lL 4 cylinder?
The 3.1 liter engine is actually a V6, not a 4cyl. It's NOT the same multiport injected 3.1 found on other cars like the Corsica, Lumina, etc of this generation because it actually uses a distributor and has throttle body injection and not multiport injection. It's pretty old school. Anyway, the firing order is just straight 1-2-3-4-5-6 and the distributor rotates clockwise.
