Fuel Engine Pump for diesel Engine 0445020168 Common Rail High Pressure Fuel Pump Original Quality 0 445 020 168 for Great Wall

The 0 445 020 168 Bosch CP3.3H High-Pressure Fuel Pump is an original equipment (OE) third-generation common rail pump designed for heavy-duty diesel engines, particularly the Yuchai YC6J, YC6G, and YC6A series. As the primary pressure source in the common rail fuel system, it pressurizes diesel fuel to extreme levels—up to 1,800 bar (26,100 psi)—and delivers it consistently to the high-pressure accumulator (rail), enabling precise electronic fuel injection across all engine operating conditions.

Featuring a radial three-plunger design, integrated ZME flow metering unit (solenoid valve), and internal gear pre-feed pump, this robust CP3.3H model ensures stable rail pressure control, supports multiple injection events, and plays a critical role in achieving Euro IV and Euro V emissions compliance by enabling ultra-fine fuel atomization.

Used extensively in coaches, buses, trucks, and construction machinery, including models from Yutong, King Long, Higer, Dongfeng, and JAC, this pump demands strict adherence to fuel quality, cleanliness, and installation procedures.
