MULTIPOINT FUEL INJECTION

Abstract

The purpose of the system in vehicles is to provide a vaporized mixture of fuel and air

to the engine for combustion. A fuel system is composed of the fuel pump two fuel filters

(one of which is a fuel strainer located in the fuel tank) pressure regulator, injectors,

distribution pipe, fuel hoses and fuel tank. It supplies the necessary amount of the injectors at

a constant pressure. This system also meters and injects the fuel into intake port according to

the injection signals from the control unit.

For most of the existence of the internal combustion engine, the carburetor has been

the device that supplied fuel to the engine and on many other machines such as lawn mowers

and .chainsaws it still is. But as the automobile evolved, the carburetor got more and more

complicated trying to handle all of the operating requirement. In trying to keep with the

emissions and fuel efficiency laws, the fuel system has changed a lot over the years. With the

failure of carburetor system, there was gradual evolution of MPF1 system that has totally

replaced the carburetor system.
