This follows from the ability of the system to calculate the optimum air/fuel mixture for starting as well as from the superior atomization that results from injection of the fuel as compared to fuel delivery from a carburetor. multi point injection b. Mono-Jetronic is different from all other known single-point systems, in that it only relies on a throttle position sensor for judging the engine load. This is the role of the low-pressure fuel system components. Fuel and exhaust systems - single-point fuel injection models 4B•3 6 To remove the air cleaner housing-to-throttle body duct, disconnect the breather hose from the side of the duct, then disconnect the vacuum hoses from the air temperature control system vacuum valve, noting their correct fitted positions. These multiple injection point nozzles provide superior spray performance with significantly higher flow rates, making them ideal for applications where higher volumes of liquid with fine drop sizes are required. System relief pressure 5,220 psi (360 bar) Drive pump controls Electro-hydraulic Pump to engine ratio 1:1 Displacement 2. Single-point fuel injection. Purchase affordable OEM car parts. Injection fuelsupply systems of SI engines • SPI -single-point injection system (to the carburettor). So in case of an MPFI engine, there is one fuel –injector installed near each cylinder, that is why they call it Multi-point (more than one points) Fuel Injection. - A variety of injection location options to suit the application. In a dry system, nitrous oxide alone is injected into the intake air stream before the throttle body. q Electrical distribution, Diesel q Ground point 3171 q Diesel ground point 3132 q Group 2328 r. You can now get the whole How A Car Works site as a beautiful PDF ebook. In have no experience with the pin point injections. The main difference between Carburetor and Fuel injection system {Carburetor zFuel is atomized by processes relying on the air speed greater than fuel speed at the fuel nozzle, zThe amount of fuel drawn into the engine depends upon the air velocity in the venturi {Fuel Injection System zThe fuel speed at the point of delivery is greater than the. If there is a leak, remove the injector fuel rail and replace all of the O-rings.
