In addition, the single module aftertreatment system allows the DPF cleaning interval to be extended to between 600,000 and 800,000 miles. Cummins also announced its OilGuard oil analysis pro- gram, which offers customers the opportunity to extend oil drain intervals as far as 80,000 miles. Light might The X12 Series engine rat- ings range from 350 to 475 horsepower and between 1,250 and 1,700 pound-feet of torque. It also sports Cum- mins' best power-to-weight ratio at 2,050 pounds, 150 pounds lighter than the next closest competitive engine, according to Cummins. Material has been re- moved from the block where possible, including the flywheel, adding struc- tural support "ribs" to add strength and rigidity. "This engine was designed from the ground up to re- move as much weight as we could while retaining superior dependability," said Fier. The X12 will share several components with the X15, including the Cummins Holset VGT Turbo, XPI fuel system, engine control module, and the single module aftertreat- ment system. After years of development and 9 million miles of testing, Cummins will begin limited production of the X15 late this year; full production will be- gin in January 2017. Custom- ers wanting the X12 will have to wait until 2018. heavy trucks | continued Vanair_Equip0916_PG82.indd 1 8/24/16 11:18 AM C ummins has also introduced a new package of engine connectivity options that give contractors the ability to update their trucks' engines over the air (OTA), with either an updated calibration from Cum- mins or specialized tunes for improving fuel economy or application changes. The company also announced an updated GPS- based predictive cruise control that gives its engines the ability to read road maps up to two miles ahead via GPS connectivity. The cruise system then uses that data to optimize acceleration and coasting for the best possible fuel economy. The updated connectivity package includes the Connected Calibrations system and Connected Tun- ing, both of which join the already existing Connected Diagnostics unveiled in March 2015. The two additions to Cummins' Connected system will be available for both of their new 15-liter engines. Cummins says the Connected Calibrations system allows the company to push out engine control mod- ule updates to its engines without the downtime as- sociated with being taken to the shop. The Connected Tuning system, meanwhile, gives owners the ability to send new engine tunes to their X15 engines to more finely tune the engine's ECM and performance to specific fleet applications. – James Jaillet Predictive cruise, OTA updates
