This means your fuel pump will, cease to function . port-type fuel injector system where the amount of fuel inj~ted is primarily determined by the engine speed, the engIne load, the engine temperature and the intake air . The setting of the opening pressure of fuel unit injector is a very important stage because it affects the volume of injection doses. If the injector does not pass these rigorous tests, the injector will have to be torn down to start all over again. Before the fuel framework duties, such as fuel lines, fuel siphons, and fuel injectors, begin, reduce the fuel line pressures. Important: Injector Flow Rate must be programmed into the ECM as part of injector replacement. Connect fuel. When an injector is replaced, program the new injector code into the ECM. H. P. Singh Machinery Private Limited. Pop-Off Pressure Test 1. The fuel pump primes when I first turn the key. So, the engine fuel system, needs to do two important things. Basic theirs work parameter influencing on correctly work parameters are magnitude injection and return dosages by definite. For compression ignition (CI) engines, two of the fuel injection parameters affecting the engine's performance and emissions formation, are fuel injection timing (FIT) and injector opening pressure (IOP). Profesional diagnose modern fuel injectors is very dificult procedure. It regulates the 9 volt battery voltage to a 5 volt reference input, required when using the TPS Tester Wire Harness (PU-47466). Buy . 6. 4. Calculating Fuel Injector Size The formula for calculating the correct size fuel injector for your Mustang is calculated by: Injector Flow Rate (lb/hr) = (Engine HP) x (BSFC) / (Number of Injectors) x (Injector Duty Cycle) Close the ON/OFF valve and the gauge protector valve.
