T-12 Meeting Minutes of January 12, 2005

Attendance - Wim van Dam, Jim McGeehan, Jeff Clark, Phil Scinto, Jim Matasic, Ken Goshorn, John Haegelin, Mike Menasco, Jim Wells, Scott Richards, Steve Kennedy, Andy Broff, David Stehouwer, Pat Fetterman, Greg Shank, Riccardo Conti, Jim Rutherford, Ron Buck, Bill Place, Charlie Passut, Tom Franklin, Mark Cooper, Jim Gutzwiller, Frank Fernandez, Bill Runkle, Brad Carter, Jim Moritz.

Membership - no changes.

Minutes - of January 4, 2005 teleconference were approved as issued.

Update of Lab Status:

LZ - at the time of the meeting, about 70 hours into a shakedown run using two new coolers and 80 deg C process water. Some problems fighting a leak in the egr system. No problems yet seen with intake manifold temperature control.

PE - 110 hours into a full test with two coolers and 80 deg C process water. Saw some fouling of the coolers, cleaned with hot water and regained intake manifold temperature control. Commented that warm-up may be a concern since the process water isn’t up to temperature and the egr hits a very cold cooler and condensation may occur. Their second stand is being built with three coolers.

Afton - stand is built with three coolers in parallel, concurrent flow. Shakedown test should start this week. Will observe water and egr temps to ensure balanced flow through three coolers.

XOM - setting up with three coolers, should start a live test next week.

SR - will not set up three coolers until the set up is proven to work.

Photos of the three cooler set-ups are attached.

During the lab updates, several discussions (some lengthy) broke out. As a result, it was agreed that BSFC will be added to the operational summary. A template will be set up for operational data to be shared among laboratories (Riccardo Conti will forward to Jeff Clark). The group may need to look at six minute data as well. Nickel will be added to the oil analysis summary. It was decided that all three cooler set-ups should monitor water and egr temps to check for balanced flow.

Procedure Items - the 80 deg C process water (or coolant) minimum will be added for the next draft.

Report Forms - BSFC will replace power, pre-venturi pressure will be added, and humidity will be dropped on the operational summary (form 5). A ring gap form will be added.

Hardware Availability - Ron Buck informed the group that all the venturis have arrived. Another intake manifold is expected this week. The next manifold will go to Afton. At this point, external hardware availability is not holding up any testing. TEI has one Modine in stock. Ken Goshorn indicated that a “3/4 Engine” is available through Mack Dealers (Basic Engine Assembly p/n 11GBA41894). This is essentially a short block with cylinder heads. January ’05 updates of Service Manuals 5-110 AI and 5-111 AC should be available.

EGR Cooler Cleaning - PE cleaned their coolers at 78 hours with 160 deg F water and regained intake manifold temperature control. No other progress has been made on this issue.

T-12 Update to Class Panel - Greg Shank review his presentation (attached).

Next Meeting - conference call on 1/27 at 10:30 am EST.
