Louisville, Ky. (March 24, 2010) -

Cummins revealed today that it is using new and proprietary datalogging and analysis technology to ensure enhanced performance and superior product reliability for its on-highway diesels for 2010.

The Engineering Tools Datalogger (ETD) is a data recorder and transmission device that automatically transmits field-use data to Cummins headquarters. This unit has the capability of sending results for 240 different variables, from engine speed and exhaust temperature to GPS location, vehicle speed, torque, fuel usage, emissions, coolant temperature and more – including On-Board Diagnostics (OBD). This information is time stamped to provide a graphic picture of engine and aftertreatment performance at any point in the duty cycle and at any location.

ETDs have been installed in over 200 field test vehicles with Cummins engines, accumulating over 35,000 “truck days” of data covering eight million miles of operation. Data has been compiled from North America, China and Australia.

Engine, vehicle and trip information is encrypted and sent via modem to the on-highway engineering team in Columbus, Ind., where it is segmented and analyzed by Cummins engineering experts. Having real-world data from so many different vehicles operating in a variety of locations and duty cycles has allowed Cummins to test engine software and algorithms, make modifications and validate operating characteristics with greater speed and accuracy than ever before. The ETD has the capability of making calibration changes to the engine, including complete recalibrations of the Electronic Control Module (ECM).

The Engineering Tools Datalogger allows Cummins engineers to optimize software and system performance reliability, and enables the continuous improvement of the engines and aftertreatment systems based on actual driving experience with fully loaded vehicles in all environmental conditions. The ETD capability has allowed Cummins to maximize passive regeneration in the Cummins Aftertreatment System as well as optimize Diesel Exhaust Fluid (DEF) consumption for all types of duty cycles. It also provided Cummins with a critical window for early failure detection and resolution, even before the first 2010 production engines were released.

Sean Milloy, Chief Technical Officer - Cummins Engine Business, described how this intelligence gathering is resulting in tangible benefits: “Having this unique tool and its ability to deliver a continuous data stream has allowed Cummins to compile, compare and contrast data from hundreds of sources automatically and instantaneously. This, in turn, has led to optimized performance and fuel economy for customers, with a higher level of confidence in the ultimate reliability of Cummins 2010 engines with Selective Catalytic Reduction (SCR) technology.”

The Engineering Tools Datalogger is a differentiating capability for Cummins relative to other engine manufacturers and provides a competitive advantage to customers. It is one of the key reasons that Cummins 2010 engines make every truck better.
