Cummins QSK23 Engine Specifications & Information

*Cummins customers can use Tier 2 engines in North America through 2017 by utilizing U.S. EPA’s Transitional Program for Equipment Manufacturers. All QSK23 ratings are available for use in nonregulated regions where engines are not subject to certification.

More Robust Features

The HPI fuel system provides optimum combustion for low emissions and excellent fuel economy.

The electronic control system allows users to tailor fuel- system calibrations to application requirements, including CENSE™ electronic monitoring, which reads engine operating conditions and automatically adjusts for peak operation.

The high-speed Electronic Control Module (ECM) is isolated from detrimental vibration loading, and the wiring harness is fully sealed to optimize reliability.

A one-piece cast-iron block with wide cylinder spacing provides long life with excellent rebuild capability.

Single-piece ferrous-cast ductile iron pistons with twin- piston cooling nozzles provide maximum durability and reliability, delivering 10 percent longer life-to-overhaul than two-piece pistons.
