SINOTRUK HOWO D12 Engine High-Pressure Fuel Injection Pump Assembly 1015569248

SINOTRUK HOWO Heavy Duty Truck Engine Fuel Injection System High Pressure Fuel Injection Pump / Fuel Pump Assembly 1015569248

The 1015569248 High-Pressure Fuel Injection Pump Assembly is the heart of the fuel delivery system for SINOTRUK HOWO D12 diesel engines. As the most precision-intensive component in the engine's fuel system, this pump performs a mission-critical function: drawing diesel fuel from the tank, pressurizing it to the extremely high levels required for direct injection (typically 1,000–2,000 bar in modern common-rail or unit-pump systems), accurately metering the fuel quantity, and precisely timing its delivery to each cylinder's fuel injector. The quality of fuel atomization, combustion efficiency, power output, fuel economy, and exhaust emissions all fundamentally depend on the injection pump's performance. Designed for heavy-duty commercial vehicle applications, the 1015569248 pump assembly is widely deployed across HOWO A7, T7H, and related D12-powered truck models operating in logistics, construction, mining, and long-distance transport.
