Cummins 3016676 PT Fuel Injector Assembly

The Cummins 3016676 is a PT (Pressure-Time) type fuel injector designed for the KTA19 series 19-liter inline six-cylinder diesel engines, specifically the KTA19-C450 rating producing 336 kW (450 HP) at 2100 RPM. This injector operates within the Cummins PT fuel system, utilizing camshaft-driven mechanical actuation to meter and deliver fuel at high pressure into the combustion chamber. It features a multi-hole nozzle pattern optimized for direct injection combustion, ensuring efficient fuel atomization, power output, and emissions compliance for Euro II standards. The injector body is constructed from high-strength alloy steel to withstand cyclic combustion pressures and thermal loads. This part serves as a direct replacement for OEM numbers 3016676 and 3096276 (associated PT pump assembly), and interchanges with rebuilt designations R-3016676. Primary applications include Sany heavy excavators, Sinotruk Howo and KZ28 series vocational trucks, mining equipment, and industrial generator sets powered by the KTA19-C450 engine.
