The Bosch Common Rail Injector injects the precise amount of fuel into the combustion chamber at the right time and in the right quantity. This can be actuated with a solenoid on the injector, and the duration and timing will be controlled by the ECU (Electronic Control Unit). Features: Operates up to 2,050 bar pressure of
11 Μαρ 2023 · The fuel pressure regulator keeps fuel pressure within a specific range, while the ECU analyzes engine load, RPM, and temperature to determine the best fuel delivery. By modifying the fuel’s quantity, timing, and pattern of injection, the fuel injection system regulates the fuel’s delivery.
2 Μαΐ 2012 · The ECU controls the amount of fuel being injected and the ignition timing by monitoring the primary sensor signals for air temperature, barometric air pressure, engine temperature, engine speed (RPM), and throttle position (load).
The fuel pressure regulator can typically be found at one end of the fuel rail in systems that include a return feed for fuel. In returnless systems, the regulator is integrated in the fuel tank near to the pump so that it is easier to access. In this case, however, the FPR is trickier to replace.
One of the more commonly misunderstood aspects of Electronic Fuel Injection (EFI) is how to select the correct size fuel injectors, fuel pump and Mass Air Flow (MAF) sensor for a particular engine horsepower output.
The common rail fuel injection system, in integration with the engine control module, performs a number of important functions to meet the requirements of modern powertrains. These functions could be classified as follows: Fuel delivery and injection timing; Injection rate modulation (pilot injections or injection rate shaping)
15 Ιουλ 2016 · Step 1: Make sure the key is off. You don’t need power for this test. Step 2: Remove injector wiring harness. There may be a slide lock that you need to move before you can press down on the tabs to remove the wiring harness. Step 3: Set DVOM to measure ohms. Set the multimeter to measure ohms.
