Subject:	T-12 Meeting Minutes of February 22 2005
1. Attendance - Phil Scinto, Mark Cooper, Jim Rutherford, Wim van Dam, Greg Shank, Frank Fernandez, Ron Buck, Ken Goshorn, Scott Richards, Jim McGeehan, Jim Matasic, Dave Stehouwer, Pat Fetterman, Tom Franklin, Jim Moritz, Andy Broff, Jim Wells, Joe Franklin, John Haegelin, Steve Kennedy, Abdul Cassim, Jim McCord, Bob Campbell, Jeff Clark, Heather DeBaun, Robert Stockwell.

2. Membership - no changes.

3. Minutes - of Feb 11 conference call were approved as issued.

4. Update at Labs
Afton - 220 hours into test on oil 820-2. Test is generally doing well. EGR coolant started at 80 deg C moved down to 60 during Phase I.
SwRI - had to aborted a test on 820-2 at 225 hours due to failed turbo (studs) and elevated copper level in the oil after the failure. Scheduled to restart the test today.
ExxonMobil - Scheduled to start on 820-2 this week.
PerkinElmer - Test finished on 820-2. Saw fluctuations in speed, load, and oil pressure which may have caused high bearing wear and lead levels.
Lubrizol - Test finished on 820-2. EGR coolant started at 60 deg C and moved down to 55 during Phase I. No issues with Phase II.

It was noted during discussion that some labs have seen boiling in the Modine cooler. Some labs have switched to parallel flow to fix; some labs added air vents.

5. Review of Test Results
Greg Shank reviewed his presentation to the class panel. <This file will be posted on the TMC website as available.>

6. Operational Data Review
Jeff Clark led the task force through a review of all operational data received to date (data available from TMC website). Some Phase I oil gallery presssure differences were noted. Lab D's new turbo seems to be forcing their venturi voltage level away from the other labs. Some concern was expressed over the +/- 0.05 CO2 specs. It was decided that more CO2 data needed to be reviewed before making a change to the specs. Labs that have not already done so are to send CO2 data to Jeff Clark.

7. Engine ECM Coolant Temperature Sensor
After some discussion, the feedback from Mack was that putting a resistor across this sensor should not affect engine operating conditions. Mack will examine and re-flash affected ECMs for any labs if necessary.

8. Hardware Inventory
Ron Buck indicated that the kits for April are still on target; he is trying to get a firm delivery date. It is expected that at least 20 kits are necessary at the start of the matrix.

9. EGR Cooler Cleaning Procedure
Afton has had success with cleaning the coolers and then running a test. EGR cooler cleaning and replacement is at the discretion of the lab. Afton's method will be a referenced document for the T-12 procedure, maintained on the TMC website. It will be noted in the procedure that this method is not mandatory, but it is an example of a method known to work.

10. Lab Visitations
The T-12 lab visit group is scheduled as follows: February 23 - PE and SwRI. March 15 - Lubrizol. March 16 - Afton. March 17 - ExxonMobil.

11. Next Meetings
There will be a conference call on Friday March 4 and a meeting (location tbd) on March 17.

Please contact me if you have any questions.
