The ISL9 features common technology with the Heavy-Duty ISX15 and ISX12 for exceptional performance. Common components include the XPI fuel system, a high-capacity Electronic Control Module (ECM) and the patented Cummins VGT™ Turbocharger from Cummins Turbo Technologies. Ratings range from 260-380 hp (194-283 kW), with 550 lb-ft of clutch engagement torque. Optional features include engine braking for better control, Rear-Engine Power Take Off (REPTO) and Front-Engine Power Take Off (FEPTO).
We’ve refined the 2013 ISL9 to deliver up to 2% better fuel economy versus the 2012 model by adding an air intake throttle that makes the EGR system more efficient and modifying the VGT™ Turbocharger to make it more efficient as well. As a result, Cummins ISL9 meets the 2014 greenhouse gas (GHG) and fuel efficiency regulations a full year ahead of schedule. Even better is the fact that maintenance intervals and related costs remain virtually unchanged. This, together with better fuel economy, delivers a lower total cost of operation to ISL9 owners.
