Changes to Membership - none.

Feb 2 Meeting Minutes - approved. (75 hours Phase I XOM, not 25 hours)

Update on Shake-Down/Testing at each Laboratory 
Lubrizol - 146 hours, test running well. It was noted that Phase II oil consumption can run into the 80s. Jim has been having some issues with the Modine leaking at a gasket. Phase I exhaust CO2 was a few tenths high. IMT control of 90 deg in Phase I was not a problem, but there was evidence of cooler fouling. The egr coolant temp started at 60 deg, at about 70 hours it was dropped to 55 deg C to keep the Modine out temp above 30 deg. Egr out (pre-venturi) temps started at 140 and climbed to 187, after the coolant temp was dropped it went to about 160 before climbing back to 185.

Afton - started the 820-2 test today. A turbo failure delayed this test start. This test was started with 80 deg egr coolant, 90 IMT, two cleaned egr coolers. Bob use hot water and tide to clean the coolers.

PerkinElmer - 820-2 test at 140 hours. Successfully got through Phase I with IMT of 90. Saw evidence of egr cooler fouling and dropped egr coolant temp to compensate (from 100 deg to 80 deg). Modine out temp was kept above 30 deg (finished at 35). This test was run with new coolers. Egr out temp (pre-venturi) started at 160 and quickly move to 180s. After the coolant temp drop the egr out temp dropped to 175 before climbing back to 180s. No problems staying within CO2 limits.

SwRI - 820-2 test with two coolers, 90 deg IMT. No problems seen in Phase I. Modine temp kept above 52 deg (65% of controller was still left). Test is at 114 hours. Saw fouling but then the system stabilized.

XOM - just finished a three cooler test. Switched to 90 IMT 25 hours into Phase I. Will be converted back to two egr coolers and then running 820-2.

Operational Data Update - pending Jeff’s completion of the data review.

Hardware Update - TEI is working on getting stainless intake manifolds to labs. Ron has 200 kits on order, expected to be delivered by April (for matrix use). There was some discussion regarding stocking on non-kit parts. This discussion likely will resume at the meeting in San Antonio. Labs are to run the ‘M7’ VGT.

Lab Visitations - The San Antonio labs will be visited on February 23. T-12 Core Visit group is Andy Broff, Jeff Clark, and Jim Moritz. The other labs are likely to be visited in March in conjunction with a face-to-face meeting and lab visits for the ISB and C13 tests.

Next Meeting - in San Antonio on February 22.
