Engine-Specific Industrial Fuel Injector |
Engineered specifically for the demanding operating conditions of the Cummins QSK23 platform, fuel injector 3766446 delivers the precise fuel metering and high-pressure injection performance required by 23-liter inline 6-cylinder, 4-cycle diesel engines. With 170 mm bore and 170 mm stroke, turbocharged and charge-air-cooled architecture, the QSK23 supports well-servicing ratings of 760–950 hp / 567–708 kW and generator outputs of 545–725 kW prime and 600–800 kW standby, making a correctly matched injector essential to combustion stability and engine protection.
This heavy-duty injector provides stable atomization, effective leakage control, and durable construction built for continuous industrial duty cycles. It serves as a direct replacement for OE 3766446 and cross-references 4088426, 4088427, 4088428, 4326639, 4326780, 4326781, 4326784, 4928346, 4928349, 4087887, and 4010163. Beyond the QSK23, related listings extend coverage to QSX23, QSK45, and QSK60 applications, supporting mining, oil and gas, construction, and power generation fleets.
Designed for fast replacement in repair shops and industrial fleets, correct installation requires confirming the injector by ESN and original marking, replacing seals, inspecting connector tubes and fuel lines, and applying torque per the Cummins service manual before priming and leak testing. Injector life depends on fuel cleanliness, timely filter service, and preventive inspection rather than run-to-failure operation. Ideal for engine rebuild shops and diesel parts distributors.
