A Better Route To Better Performance. Cummins ISL9 clean diesel engine combines proven reliability with exceptional durability. Years of bus duty in tough urban routes provide ample evidence that its high power-to-weight ratio, replaceable wet liner design, roller followers, bypass oil filtration, targeted piston cooling and other heavy duty engine features set the standard for others to follow. It uses the XPI fuel system, and shares the same high capacity Electronic Control Module (ECM) with all other Cummins on-highway diesel engines, for powerful, smooth, quiet performance. Plus, because cleaner is better, the ISL9 already meets 2014 GHG and fuel economy standards, getting 2 percent better fuel economy versus the previous model. Clean diesel ratings are available at 280 hp (209 kW) and 330 hp (246 kW) with up to 1100 lb-ft (1493 N•m) of peak torque. A diesel-electric hybrid rating is available at 330 hp (246 kW) with a peak torque of 1100 lb-ft (1493 N•m). The ISL9 has the street smarts to make every urban transit operation run better. Every bus. And every route.
