The Cummins ISB6.7 is the most flexible option in the lineup. With a horsepower range of 200-325, the ISB6.7 is the perfect all-arounder for typical jobs.

Best in class for reliable uptime, this engine balances performance with high fuel economy for a clear improvement in any fleet’s bottom line. For jobs ranging from  deliveries to dump trucks, the ISB6.7 packs big results.

But how does all that reliable power work in such a flexible design? Much of that lies in the first-rate engine technology Cummins engines are manufactured with.

Engine Technology in the Cummins ISB6.7

VGT™ Turbocharger – The Cummins VGT Turbocharger is both simple and precise. Electric actuation allows infinite adjustment, providing the exact amount of boost necessary for superior response. The proven sliding-nozzle design has best-in-class reliability and durability.

Lowest Cost of Operation – You can rely on the Cummins ISB6.7 to keep operating budgets in line with reduced maintenance, long service intervals and the best fuel efficiency of any engine in its class.

HPCR Fuel System – The HPCR fuel system delivers a precise mixture of fuel and air at a constant pressure, regardless of engine rpm. This flexibility in injection timing allows multiple injection events per cycle, which maximizes fuel economy and performance while decreasing noise and exhaust emissions.

Cooled EGR – This next-generation system lowers combustion temperatures for reduced emissions and optimized fuel economy.

Fully Integrated Electronic Controls – A single higher-capacity Electronic Control Module (ECM) controls everything from air intake to exhaust aftertreatment for peak performance and near-zero emissions.

Cummins Aftertreatment SystemCummins Aftertreatment System – The proven Cummins Particulate Filter reduces particulate matter by over 90%. In 2010 it is combined with Cummins SCR to meet emissions standards while maintaining best-in-class performance, reliability and durability. Cummins SCR technology has been proven in over 200,000 European vehicles and uses Diesel Exhaust Fluid (DEF) to achieve NOx emissions at near-zero levels.
