Bosch Common Rail Fuel Injection Pump 0445 020 031 - CP3 High Pressure Pump (Doosan/Daewoo DL08)

Shengkunda provides the Bosch Common Rail Fuel Injection Pump 0445 020 031 - CP3 High Pressure Pump (Doosan/Daewoo DL08) as a precision-matched replacement for Doosan and Daewoo industrial engines. This fuel injection pump new bosch for daewoo doosan dl08 utilizes a advanced three-plunger internal design to provide a constant high-pressure fuel supply to the common rail. Unlike older systems, the 0-445-020-067DR (65.10501-7005) Bosch CP3 Injection Pump for DAEWOO DOOSAN includes an integrated Metering Unit (ZME) that accurately regulates fuel flow before pressurization. This ensures the engine control unit (ECU) can manage injection timing with extreme accuracy, effectively resolving "low rail pressure" codes and restoring full engine horsepower.

Main Features

● Tri-Plunger High-Pressure Stability
The Bosch Common Rail Fuel Injection Pump 0445 020 031 - CP3 High Pressure Pump (Doosan/Daewoo DL08) has three small pistons arranged in a radial configuration to compress diesel fuel. This design ensures a steady, pulse-free supply of high-pressure fuel, which is critical for maintaining stable combustion and reducing engine noise during heavy-load operations.

● Integrated Fuel Metering Control
The built-in ZME/M-Prop valve allows for granular control over the volume of fuel entering the pressurization chambers. By only pressurizing the required amount of fuel, the pump reduces the parasitic load on the engine, leading to improved fuel economy and reduced heat generation.

● Heavy-Duty CP3 Structural Integrity
As a genuine CP3 series pump, this unit is engineered for long-term durability in excavators and loaders. The internal components are manufactured with high-strength alloys treated to resist wear from varying fuel qualities, ensuring reliability in high-vibration environments.

● Exact OEM Fitment
The mounting flange and drive shaft dimensions are produced to original equipment standards. This ensures a perfect mechanical match for the DL08 engine block, preventing the oil leaks or timing misalignments often associated with low-quality aftermarket pumps.

Product Application

This Bosch Common Rail Fuel Injection Pump 0445 020 031 - CP3 High Pressure Pump (Doosan/Daewoo DL08) is specifically designed for Doosan and Daewoo DL08 engines. It is the standard replacement part for heavy machinery, including DX300 and DX340 series excavators and wheel loaders, where consistent rail pressure is vital for hydraulic system performance.

What's its Advantages Over Traditional Mechanical Pumps?

Unlike old-fashioned mechanical pumps that physically timed the injection, the Bosch Common Rail Fuel Injection Pump 0445 020 031 - CP3 High Pressure Pump (Doosan/Daewoo DL08) functions purely as a pressure generator. By separating pressure generation from injection timing, the system allows the ECU to perform multiple injection events per stroke. This results in significantly higher torque, cleaner emissions, and smoother operation. Furthermore, the electronic metering unit allows the system to build starting pressure even at low cranking speeds, ensuring faster and more reliable ignition than older mechanical systems.

FAQ

Q: Will this pump resolve a "Low Rail Pressure" error code?
A: Yes, provided that your fuel filters and sensors are functioning correctly, a worn CP3 pump is the primary cause of low rail pressure. Replacing the unit restores the ability to reach the 1600+ bar required by the ECU to maintain full power.

Q: How does the Metering Unit (ZME) affect engine starting?
A: The Metering Unit controls the volume of fuel pressurized by the plungers. If the valve or the pump's internal components are worn, the system cannot build the minimum pressure required for the computer to allow the injectors to fire, leading to "no-start" conditions.

Q: Is this pump a direct replacement for part number 65.10501-7005?
A: Yes, the 0445020031 is the Bosch cross-reference for the Doosan/Daewoo 65.10501-7005 and 0445020067 series. It is a direct functional and physical match for the DL08 engine common rail system.
