Subject:	T-12 Task Force Minutes of 10-15-04
Attendance - Jeff Clark, Bob Campbell, Pat Fetterman, Jim Gutzwiller, Riccardo Conti, Tom Franklin, Jim Matasic, Greg Shank, Ron Buck, Scott Richards, Jim Moritz, John Haegelin

Membership - no changes.

Minutes of 10/08 TelCon Minutes - approved as issued.

Hardware Update -
Modine cooler (R.Buck): Ron indicated that there was not enough interest to purchase a lot of ten with the discount. Ken will continue to see if he can work a better price from the supplier. Lead time for delivery seems to be about two weeks. Riccardo and Andy Broff will send out the supplier information (Riccardo's information is shown below).

It is a Waukesha Intercooler (part number 305781B) but we purchased it
from the following:

Cylinder head availability (P/N 732GB3494M2): There are only about 5 of the p/n 3494 available. The 3499 is the same head with different valve guides. Either head is acceptable for the T-12, provided that the new valve guides (p/n to be provided by R. Buck) are used. Ron Buck agreed to work with Ken Goshorn and Andy Broff to develop a complete parts list.

EGR Cooling Loop Heat Exchangers and Heat Loads: SwRI and/or ExxonMobil will provide information on these immediately.

EGR Cleaning Procedure - This is still an open issue. No new progress has occurred on this. Hot water and soap will be investigated first and if necessary ultrasonic or chemical cleaning will be investigated.

Some operational targets - the first pass at the CO2 limits are shown below. These cannot be completely confirmed until more labs are running.
      Phase I
      CO2 Intake: 3.09 +/- 0.05
      CO2 Exhaust: 9.25 +/- 0.05
      TGA Soot:  4.30 +/- 0.30 % @ 100-h (suggested inj timing: 6.0 BTDC)

      Phase II
      CO2 Intake: 1.42 +/- 0.05
      CO2 Exhaust: 10.0 +/- 0.05

Oxidation Measurements - concern was expressed about the status of oxidation measurements. It is understood that a workshop will be coming very shortly.

Next Meeting - 8:30 am, Wednesday, October 20th, 2004 at SwRI Bldg 209, Conference Room 103.
