Overview:

The Most Popular Diesel Engine For RVs.

For years, no engine has combined proven reliability, power and towing capacity, fuel economy and high resale value better than the Cummins ISB6.7. Modifications to the turbocharging and control system have enabled lower emissions while delivering better fuel economy than that of prior models, lowering operating costs and leaving more dollars in your budget for trips you enjoy.

A Cummins-designed and manufactured aftertreatment system is fully integrated, and includes On-Board Diagnostics that continuously monitor engine and aftertreatment performance to ensure near-zero emissions.

Customizing the performance of your engine is possible through the use of Cummins PowerSpec, an online tool that lets you adjust operating parameters to match your need for enhanced fuel economy, higher performance or a balance between the two.

All of this is backed by unmatched support from the largest service network in North America, including the exclusive Coach Care™ program and 24/7/365 assistance from Cummins Care representatives at 1-800-DIESELS™ (1-800-343-7357).

  • High Pressure Common Rail (HPCR) Fuel System – High injection pressures produce quick throttle response at every rpm, for safe entry onto highways. Optimized timing increases fuel efficiency while lowering emissions.
  • VGT™ Turbocharger From Cummins Turbo Technologies – This patented design is widely recognized as the industry leader for performance. Electric actuation provides quick throttle response and increased braking horsepower.
  • Cooled Exhaust Gas Recirculation (EGR) – The next-generation system lowers combustion temperatures for reduced emissions and optimized fuel economy.
  • High-Capacity Electronic Control Module (ECM) – A single ECM manages the entire engine and aftertreatment system for optimum performance and fuel economy. This ECM is used across the board for Cummins on-highway engines, to simplify servicing.
  • Cummins Aftertreatment System From Cummins Emission Solutions – This proprietary system consists of a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) technology, for near-zero emissions.
  • Fleetguard®Fuel Filters, Lube Filters And Diesel Exhaust Fluid (DEF) From Cummins Filtration – Fleetguard filters protect against corrosion and contaminants that can cause performance issues. High-quality DEF is readily available at all Cummins distributors, within Cummins Filtration’s vast North American distribution network and at major service stations and truck stops.
