Rock-solid performance makes the QSK45 the engine of choice for your toughest applications in the toughest possible conditions. The 12-cylinder QSK45 combines the exceptional durability of Cummins K Series with a sophisticated electronic control system and CENSE™ engine monitoring. Every component is designed for superior uptime - from its ductile iron pistons to a 38% larger camshaft (for multiple rebuilds), to an extra-wide gear train with high-contact ratio spur gears for handling higher load factors with maximum durability. It delivers exceptional performance and durability with low maintenance and operating costs.

Available in ratings from 1200-2250 hp, the QSK45 uses advanced Quantum System electronics and robust features for superior reliability and durability.

And the QSK45 also meets Tier 2 emissions standards* without compromise.

Every QSK45 engine comes with a full-coverage base warranty on the engine and branded components with unlimited hours during the first year of operation, with 3-year/10,000-hour standard protection on major components.

* The QSK45 meets Tier 2 standards in the U.S. now, which go into effect in 2006 for engines over 750 hp. Cummins Quantum System engines are designed to meet every applicable emissions standard from Tier 1 to Tier 3, and Stage II to Stage III with in-cylinder technology.

 

High technology meets high durability in the QSK45. With its V12 configuration, heavy-duty components and reduced maintenance features, the QSK45 is designed to set new standards for productivity. Its Quantum System full-authority electronic controls take productivity to a whole new level with complete engine control and monitoring for superior performance, fuel efficiency, diagnostics and prognostics. Programmable parameters let you customize engine performance for specific equipment use. And its High-Pressure Common-Rail (HPCR) fuel system maintains high injection pressures regardless of engine speed for exceptional performance. At every rpm.
