Injection Pump 0445020273 610800080979 for Weichai Engine - High-Pressure Common Rail Fuel Injection Pump

High-Quality Injection Pump 0445020273 (Alternative Part No.: 610800080979) is a precision-engineered fuel delivery core, specifically designed and calibrated for Weichai diesel engines. As a critical component of the common rail fuel system, this injection pump ensures stable fuel supply, efficient atomization, and optimal engine performance, making it the ideal replacement part for Weichai engine maintenance and repair. Compatible with a wide range of Weichai engine models, it solves common issues such as unstable idling, insufficient power, and excessive fuel consumption, while meeting global industry standards for durability and reliability.

Product Overview & Compatibility

This injection pump is a high-pressure common rail type, engineered to match the exact specifications of Weichai diesel engines—widely used in heavy-duty trucks, construction machinery, agricultural equipment, and industrial generators. It is officially cross-referenced with two key part numbers: 0445020273 and 610800080979, ensuring a perfect fit and direct replacement without any modifications to the engine’s fuel system.

Key Compatibility: Designed exclusively for Weichai engines, including but not limited to Weichai WP series (WP10, WP12) and other heavy-duty engine models that require precise fuel injection control. It is a direct OEM-compatible replacement, adhering to the same manufacturing standards as the original equipment, ensuring seamless integration and consistent performance.

Core Features & Technical Advantages

• Precision Fuel Metering: Equipped with advanced inline plunger configuration and high-precision fuel control valve, it delivers accurate fuel volume to each cylinder, ensuring uniform combustion, reducing exhaust emissions, and meeting European emission standards. The precise fuel metering also prevents engine surging and black smoke under heavy load conditions.

• High-Pressure Performance: Built to withstand high injection pressure (up to 120 Mpa), it ensures efficient fuel atomization, maximizing fuel-air mixing efficiency and improving engine power output by 8-12% compared to worn or low-quality injection pumps. This high-pressure capability is critical for maintaining the thermal efficiency of Weichai’s large-displacement engines.

• Durable Construction: Made of high-strength alloy materials and use strict heat treatment, the pump body and internal components (plunger, delivery valve) resist wear, corrosion, and high temperatures. It features a sealed design that prevents fuel leakage and extends the service life to over 10,000 operating hours, reducing maintenance frequency and costs.

• Easy Installation & Calibration: Pre-calibrated at the factory to match Weichai engine parameters, it can be directly installed without additional adjustments, saving maintenance time and labor costs. The compact design ensures it fits perfectly in the engine’s original mounting position, compatible with existing fuel lines and connectors.

• OEM-Grade Quality: Manufactured in accordance with Bosch common rail system standards (referenced by part number 0445020273), it undergoes strict quality inspection (including pressure testing, leakage testing, and performance testing) to ensure consistency and reliability, meeting the highest industry standards for Weichai engine spare parts.
