0 445 010 169 Common Rail Fuel Injection Pump 0445010169 Brand New!

The 0445010169 Common Rail Fuel Injection Pump has the following key functions:

1. Fuel Pressurization: Boost low – pressure fuel to meet the injection pressure requirements, enabling good atomization.
2. Precise Fuel Control: Accurately control
3. Combustion Optimization: Support multiple injections to improve combustion conditions and reduce emissions.
4. Pressure Stabilization: Maintain a stable fuel pressure in the common rail tube to ensure consistent fuel injection.

Working Principle of 0445010169 Common Rail Fuel Injection Pump

1. Low – pressure Fuel Supply Phase：Fuel is drawn from the fuel tank. It first passes through an oil – water separator to roughly remove water, then through a diesel fine – filter to further filter impurities. After that, it enters the low – pressure fuel pump, which delivers fuel to the high – pressure fuel pump for a stable supply.
2. High – pressure Fuel Generation Phase：Driven by the engine via couplings, gears, chains or toothed belts, the high – pressure fuel pump rotates at half the engine speed. Inside, there are multiple pump plungers. For instance, Bosch has a three – cylinder radial plunger pump, and Denso has an in – line pump with a three – acting cam. Taking the three – cylinder radial plunger pump as an example, when the plunger moves downward driven by the cam, the inlet valve opens for low – pressure fuel to enter the cavity. Once at the bottom dead center, the inlet valve closes. As the plunger moves upward, the fuel is pressurized. When the pressure reaches a certain level, the discharge valve opens, sending high – pressure fuel to the common rail.
3. Fuel Pressure Regulation Phase：A pressure sensor on the common rail
4. Fuel Injection Phase：When the ECU decides fuel injection is needed, it commands the injector’s solenoid valve to open. High – pressure fuel from the common rail is injected into the engine’s combustion chamber through the injector’s nozzles. The ECU precisely controls the valve’s opening time and frequency to accurately regulate fuel injection volume, timing and rate, meeting the engine’s combustion demands under different conditions, such as pre – injection, main injection, post – injection and multi – injection strategies.

Maintenance Methods of 0445010169 Common Rail Fuel Injection Pump

1. Regular Fuel Filter Replacement: Replace the fuel filter regularly as per the vehicle’s user manual. Generally, it is recommended to do so every 10,000 – 20,000 kilometers, or shorten the replacement cycle according to the usage environment and fuel quality. This ensures fuel cleanliness, preventing impurities from entering the common rail fuel injection pump and injectors, which could cause blockages or wear.
2. Maintain Fuel Quality: Use high – quality fuel that meets the vehicle’s requirements. Avoid using inferior fuel or fuel with high impurities and water content. Refuel at regular gas stations as much as possible. Also, avoid driving with a low fuel level for extended periods to prevent sediment at the bottom of the fuel tank from being sucked into the fuel system, affecting the normal operation of the common rail fuel injection pump.
3. Inspect Fuel Pipes and Connections: Regularly check fuel pipes for damage, aging, and leakage. Replace them promptly if any issues are found. Meanwhile, check if the connection parts of the pipes are loose and ensure they are firmly connected to prevent fuel leakage and air from entering the fuel system, which may affect the normal pressure and effect of fuel injection.
4. Clean Common Rail and Injectors: Clean the common rail and injectors with professional fuel system cleaners at certain mileage or time intervals. This removes internal carbon deposits, gums, and dirt, restores the normal injection performance of the injectors, and improves fuel injection accuracy and atomization. It is generally advisable to conduct a professional fuel system cleaning every 20,000 – 30,000 kilometers.
5. Check High – pressure Pump Drive Components: Check components like the drive belts, chains, and gears of the high – pressure fuel pump for wear, looseness, or breakage. Replace or adjust them immediately if any abnormalities are detected. Also, ensure good lubrication of these drive components and replace the lubricating oil according to the specified maintenance cycle to reduce wear and ensure the normal drive and operation of the high – pressure fuel pump.
