Cummins kicked off the Mid-America Trucking Show this week by previewing its 2017 model 15-liter ISX engine, which it says is already fully compliant with the 2017 EPA deadline to reduce greenhouse gas emissions and increase fuel economy.
Details remain sparse, of course, but Srikanth Padmanabhan, Vice President of the company’s engine business noted that the ISX15 will feature enhancements including a more efficient turbocharger and reduced parasitic energy loss. The engine will be offered in distinct designs optimized for either performance or fuel economy. Power ratings will range from 400 to 605 horsepower.
Cummins also announced changes to its exhaust aftertreatment system, unveiling a new single-module system will debut alongside the 2017 ISX. Srikanth says the new system is an evolutionary design that leverages both customer input as well as Cummins Filtrations’ acquired after-treatment expertise. The system will be 60 percent smaller and 40 percent lighter than current after-treatment systems and will use new catalytic materials and DPF dosing methods to achieve reliable emissions compliance.
The engine maker also announced it will be taking more than 10 Cummins-powered trucks from various truck OEMs on a cross-country road tour to put the company’s latest technology on display, including the 2017 ISX, its SmartAdvantage powertrain, its new ADEPT powertrain, its natural gas engine offerings and its latest telematics system.
In business news, Dave Crompton, president of Cummins engine business, noted that more than 50 percent of all commercial engines in the United States today are powered by Cummins medium- and heavy-duty engines.
Crompton said Cummins earned $19.2 billion last year, with 56 percent of that revenue coming from its North American operations.
