Subject:	T-12 Minutes of the Jan 27 2005 Teleconference
Roll Call - Jose Gutierrez, Jeff Clark, Bob Campbell, Riccardo Conti, Jim Moritz, John Haegelin, Jim Matasic, Scott Richards, Andy Broff, Ron Buck, Steve Kennedy, Greg Shank.

Changes to Membership - none.

Approval of 01/12 Meeting Minutes - approved as issued.

Update on Shake-Down/Testing at each Laboratory with 80 C EGR Coolant Inlet Temperature:

PerkinElmer - no new experience from last meeting (2 coolers, fouled in Stage 1, coolers were cleaned, IMT control returned). Stage 2 completed without issue. No nickel was found in the oil drain. They will run 25 hours, 100 deg C process water, 80 deg C IMT, two or three coolers

Lubrizol - finished 100 hours this moring, some difficulty getting AFR stabilized. Coolers appeared to foul, but IMT control was maitained. No nickel seen yet in the oil analysis.

Afton - finished 100 hours with three coolers. The coolers fouled, IMT control was sketchy from 80 to 100 hours. Afton also experimented with IMT of 100, some problems occurred and the origins are unknown at this time (possible head gasket).

ExxonMobil - 30 hours into stage 1, some evidence that the coolers are already starting to foul.

SwRI - running with two coolers, lower process water temp. Made it through 100 hours maintaining IMT, coolers did show signs of fouling. They will try 90 deg C IMT and report back to Greg and the group.

A decision regarding IMT, process water temp, and cooler cleaning/replacing will be made before the next round of 820-2 tests begin (next week).

Warm-up Procedure - discussion centered on opening the egr valve sooner; labs will distribute their procedures for review and the group will settle on a procedure.

Status of Mack T-12 Test Procedure-Draft and Report Packet T12-20050125 - procedure update is pending decisions on coolers and intake manifold temp. Report packet has been distributed for use.

Template for Operational Data - Riccardo has distributed data from one of his tests. His spreadsheet is to be used as a template and the data is to be sent to Jeff Clark.

Hardware Update - no major issues pending other than Afton needs an intake manifold.

EGR Cooler Cleaning Procedure - no action at this time. This may become a bigger issue depending on next week's decisions.

Injection Timing Phase 1 - Afton between 5.1 and 7.5 degrees; SwRI between 4 and 9; PE between 6 and 7.8; XOM around 7.2.

Next TelCon/Meeting - Wednesday, Feb. 2 at 11:00 am EST. There will likely be a February 22 meeting in San Antonio.
