Proven Power. Every Call. ISB6.7 for EPA 2010.

For superior performance at every rpm, Cummins ISB6.7 EPA 2010 is best-in-class. Its High Pressure Common Rail (HPCR) fuel system delivers an optimum balance of performance, emissions control and fuel economy across the entire operating range.

The ISB6.7 incorporates a fully integrated aftertreatment system that combines cooled EGR with proven Selective Catalytic Reduction (SCR) technology. This proven technology delivers near zero emissions, while getting more power out of every drop of fuel.

From the reliability and durability you’ve come to expect from a Cummins B Series engine, to the power and efficiency of our latest technology, the ISB6.7 delivers it all.  Every call.

More information on the standard features and maintenance intervals for this engine are available online or by speaking with your Cummins representative.

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.

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 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-inclass 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. DEF will be readily available; reference Cummins Filtration flyer LT15618 for more information.
