QSL EVERY JOB. FOR OFF-HIGHWAY APPLICATIONS

There is no substitute for power when your equipment needs it. That’s why Cummins QSL offers ratings from 280-365 hp and a torque rise of up to 50%. QSL engines combine advanced in-cylinder combustion technology and a High-Pressure Common-Rail (HPCR) fuel system to increase power and reduce emissions. At the same time, the QSL delivers better cold starting and runs 50% quieter for increased operator comfort. Every day. QSL engines currently meet Tier 2/Stage II emissions standards and – in January 2005 – will meet every Tier 3/Stage IIIA emissions standard without cooled Exhaust Gas Recirculation...

Features And Benefits. Standard features on the QSL for off-highway applications include: ¡ High-Pressure Common-Rail Fuel System (HPCR) – Delivers high injection pressures – independent of engine speeds – for improved throttle response, low-end torque and fuel economy. ¡ Full-Authority Electronic Controls – Provide seamless integration with other components to optimize engine operation and deliver critical information. ¡ Integrated Block Design – Fluid circuits are integrated, replacing hoses and eliminating potential leaks. High-capacity cooling and lube systems lower temperatures, increasing...

Maintenance Intervals. QSL engines are designed to run up to 500 hours between scheduled maintenance stops, including oil, oil filter and fuel filter changes. Cummins Advisor. Getting every installation right – the first time – is what Cummins Advisor is all about. Advisor software builds a virtual model to make sure every system (air, intake, exhaust, cooling, etc.) is integrated for optimum performance. It takes into account everything from load factors to operating climates to duty cycles – then identifies systems or components that could negatively impact reliability – listing alternatives...
