Qsk Injector Nozzle

The QSK injector nozzle is a key component of the fuel injection system used in Cummins QSK series engines, which are heavy-duty diesel engines often found in mining, marine, locomotive, and power generation applications.

QSK Series Engines: These are large-displacement, high-horsepower engines made by Cummins, such as QSK19, QSK38, QSK60, etc.

Injector Nozzle: This is the tip of the fuel injector, responsible for atomizing the diesel fuel and spraying it in a fine mist into the combustion chamber at high pressure. The nozzle ensures proper fuel-air mixing for efficient combustion.

Key Features of a QSK Injector Nozzle

High-precision orifice holes for accurate fuel spray pattern.

Built to handle ultra-high pressure (often over 30,000 psi in common rail systems).

Durable materials to withstand heat and pressure over long operating cycles.

Works with electronic unit injectors (EUI) or common rail fuel systems, depending on the QSK engine version.
