Reporting more than 12,000 orders for new engines that meet EPA's '02 emissions regulations, Cummins says its compliant heavy-duty diesels have proved their reliability and performance in over 37-million miles of real-world operation.
As a result, Cummins has extended its “Uptime Guarantee” by nine months, to the end of 2003, offering to reimburse users for up to three days' truck rental if one of its new ISX or ISM engines can't be repaired within 24 hours.
“To date, we've only had six uptime claims, and not one of them involved cooled EGR or variable turbocharger systems,” said Joe Loughrey, president of Cummins' engine business.
The engine maker also announced an advanced electronic speed control for ISX and ISM diesels, as well as a new 385-hp. fleet rating for the ISX.
The Load-Based Speed Control (LBSC) is designed to improve fuel economy while satisfying driver requirements for power. An “intelligent” electronic device, it limits engine speed under low and intermediate power loads, but allows drivers to extend engine limits from 1,800 to 2,000 RPM when climbing grades.
For LTL fleets that want higher displacement engines, the new ISX 385 ST provides peak torque of 1450 lb.-ft, jumping to 1550 lb.-ft. when the transmission is in the top two gears. Like all ISX ratings, it complies with the '02 emissions standards.
Cummins also announced that it has upgraded its PowerSpec Internet application to allow fleets to read and clear fault codes, collect trip information and provide gearing recommendations. www.cummins.com or 300
