MULTI-PORT ELECTRONIC FUEL INJECTION (MPI) is to supply a precise amount of fuel to an engine’s cylinders in order to properly operate the engine at a particular moment. Since the Engine’s Condition Is Constantly Changing (RPM, load, temperature, etc.), the amount of fuel that is injected into each cylinder must change along with the engine’s requirements. To instantaneously determine the Correct Amount Of Fuel to be injected, a COMPUTER CALLED AN ELECTRONIC CONTROL UNIT (ECU) is used to calculate how much fuel the engine requires at that moment.
VARIOUS ENGINE SENSORS CONSTANTLY INPUT INFORMATION TO THE ECU SO THAT THE FUEL REQUIREMENT IS SATISFIED AT ALL TIMES.
This precise fuel metering capability allows the engine builder/designer to optimize engine operation for a specific result such as FUEL ECONOMY, EXHAUST EMISSIONS, HORSEPOWER Horsepower (hp) is a unit of measurement of power, or the rate at which work is done) Formula >> hp=fd/t, hp=horsepower , f= force in pound, d= distance in feet , t= time in minutes.

System Overview

The Electronic Fuel Injection System can be divided into THREE MAIN SUBGROUPS:

●FUEL SUPPLY SYSTEM

●SENSING SYSTEM

●DATA PROCESSING/FUEL METERING SYSTEM

Fuel Supply System

The Fuel Supply System PRIMARILY consists of the Hardware used to bring fuel into the engine. Figure 1 shows the basic fuel system components in a Multi-Port Fuel Injection System.
