1. Industrial Duty Cycle Collection  This will be added to GCE as a template that should be followed: –For determining parameters to log –For what types of plots to create with the raw data –For determining who to include in the follow-up communication review –For how to present the data when performing the follow-up communication after the data has been collected and processed.

2. Parameters to collect (minimum)

4. Type of plots to create (minimum)  Percent Time as function of Torque and Speed  Percent Fuel Used as a function of Torque and Speed  Time History of Engine Speed and Load  Time History of Various Temperatures

5. Follow-up Communication / Review  The following people are to be included in a review once the data has been collected and processed (list of names as of September 2010): Brian Hartley David Dixon Keith Nolting Scott Towsley Scott Decker Rob Morris Josh Harris Joe McIntier Bob Kern Pete Christianson Rusty Stovall Tom Elliot Rick Vreeland Mark Dozier Lynn Zopff Jim Scarbrough Eric Benz Anne McLaren Steven Brooks Jessica Kuehner Brian Alderfer James Olmstead Chris Lane Rebekah McIntier Andrew Hobbs Axel Zurloye Jason Beckort Paul Hartstirn Randy Bergstedt Zachary Knutson

6. Template to use for follow-up communication  The rest of the slides in this presentation are what should be used once the duty cycle data has been collected, specific plots have been created, and a follow-up communication review is ready to be held. This is the presentation that will be given to the people listed on the previous slide. Be sure to read the Notes in the notes section under each slide to know what to include in each slide.

19. Engine Operating Conditions Summary

23. 1 hour time shown

24. 10 minutes time shown

25. Summary of Results  The 14000 machine showed an average of 30.3% load factor during customer construction site operation. This should be considered a very representative duty cycle of crane operations  83.9% of the time below 50% Load Factor  Results show engine at idle speed and low load operation over 70.3% of the time  Temperatures on Average: Oil & Coolant 181 deg F, Intake Manifold: 88 deg F
