T-12 Task Force Membership - Richards, Moritz, Matasic, Campbell, Conti, Goshorn, Clark, Cooper, Buck, Gutzwiller

Scope & Objectives
Main objective is to deliver the test for PC-10. Action Item - Jeff Clark will draft a more formal Scope & Objectives statement

Timeline
We need to deliver the test (procedure, possibly discrimination data) by December 7 to the class panel to move forward in the PC-10 matrix. This would necessitate a draft of the procedure by the end of October. Data to be generated in November, with time to review prior to the December deadline. The test procedure will be based on the T-10 operations, with some modifications.

Hardware <please see the email with attached files from Ken Goshorn, it contains a lot of vital information>
T-11 low swirl heads (732GB3499M), pistons and rings; new injectors; variable geometry turbo; the large modine cooler will be necessary and it will have to be obtained through TEI. Mack is also interested in ring wear measures in addition to weight loss. Post-test ring gap measurements will be necessary and Mack stressed that all parts should be kept for later inspection. A ring wear sub-group was formed, consisting of Goshorn, Richards, Moritz, Matasic, Conti, Campbell, and Cooper. It was mentioned that an SAE standard (HS2200) exists for measuring wear on keystone rings. Action Item - Ring Wear sub-group is to investigate addition methods of measuring ring wear.

Oil pumps - concerns over using obsolete oil pumps for carrying the test forward. TEI was asked to search for more old oil pumps (p/n 315GC465BM) and pump gears. The general feeling was that pumps last for a while and the current supply is likely sufficient.

Engine blocks - similar concern using obsolete blocks, the new blocks have wider oil passages. After much discussion,  TEI was requested to search for old blocks (p/n 239GB5536M) and report back to the group. Ron was also requested to check on availability of the new blocks (p/n 239GB5551M).

EGR cooler cleaning - concerns exist about getting the egr coolers clean.

CO2 limits - some discussion occurred that both intake and exhaust CO2 limits will be necessary.

Next Meeting - after information about block availability is obtained. The call was set for October 1 at 10:00 am Eastern.

Please contact me with corrections or questions.
