The QSK50 builds upon its legendary robustness with enhanced engine power and improved reliability while in compliance with EPA Tier 4 and EU Stage V emissions regulation. MODULAR COMMON RAIL FUEL SYSTEM (MCRS) - Provides precise control of the fuel ejection event that results in lower noise, vibration and smoke, and optimized fuel economy. A SMARTER FUEL SYSTEM - Means optimal fuel economy. The system provides constant high injection pressure regardless of engine speed or load condition. CUMMINS HHP SCR - By using SCR technology, we’re able to protect engine performance and power density, while improving fuel economy over previous engine models, without increasing heat rejection or the engine footprint. PERFORMANCE FILTER TECHNOLOGY - NanoNet® Advanced Media Technology filters out the smallest impurities that impede optimal engine performance. DOUBLE THE FILTER LIFE - NanoForce® Air Filters can more than double your filter life while extending maintenance intervals, keeping your engine running longer and improving COP. All this performance is available in a wide range of heavy-duty front-end loaders, excavators, and haul trucks, with engine power outputs from 1500 hp to 2000 hp (1119-1491 kW). Whatever you need, the QSK50 delivers.
