MULTI POINT FUEL INJECTION SYSTEM
MULTI POINT FUEL.ppt (Size: 749 KB / Downloads: 102) INTRODUCTION MPFI- a technology used in petrol engines Uses a small computer to control the car’s engine In MPFI engine one fuel –injector is installed near each cylinder ,that is why it is called multi point fuel injection. Before MPFI system, there was a technology called “Carburetor” OBJECTIVES power output fuel efficiency emissions performance ability to accommodate alternative fuels reliability drivability and smooth operation initial cost maintenance cost diagnostic capability range of environmental operation Engine tuning HISTORY AND DEVELOPMENT Herbert Akroyd Stuart developed the first system The first use of direct gasoline injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in 1925 One of the first commercial gasoline injection systems -a mechanical system developed by Bosch and introduced in 1952 on the Goliath GP700 and Gutbrod Superior 600 Electronic fuel injection systems First commercial EFI system was Electrojector- developed by the Bendix Corporation EFI system in the Rambler was a far more-advanced setup than the mechanical types. BASIC FUNCTIONS Exhaust air or oxygen sensor Engine temperature sensor Air flow sensor Throttle position sensor Manifold pressure sensor Camshaft position sensor Knock sensor |
