Management Board

Unconfirmed Minutes from the last Management Board meeting, held on 14th May 2012 are available to CEC Group Members on the CEC Web Site.

CEC Elastomers

Confirmation has been received that ACEA supports the SG-L-039 proposal regarding the new AEM Elastomer and the group’s plan for further work on this.
ACEA has also advised that Daimler has informed them that they plan to follow the same route as ACEA for their future in-house requirements.  This information has been passed on to the SG-L-039 Elastomers Group.
A small Task Force, led by Sebastien Vautier of PSA, has been carrying out some investigations on alternative Elastomers manufactured with non-toxic components to replace the existing ones used in CEC L-39-96 and elsewhere in Industry.  
ACEA, ATC and ATIEL will review the detail within their own organisations and if possible offer up some additional specialists to work in the Task Force, as well as reporting back to CEC with their comments about the proposals at the next CEC Management Board Meeting.
Opinions are needed from all the OEMs about these new Elastomers, whether RE4 (NBR) tests are still required if RE4 (HNBR) tests are included instead and if the information provided would encourage them to use CEC Elastomer tests in place of in-house tests in the future.
Overall, the proposal promotes a new and cleaner system with more relevant to market materials.

TDG-T-108 – FZG Pitting Test

The first meeting of CEC TDG-T-108 has taken place and all Group Officers have been elected from the 19 participating companies. A request for calibration oils has been made.

TDG-L-107 – M271 EVO Sludge Test

The Fuels Sub-Group has met twice and a draft reference fuels tender has been produced.  
This is in the process of being checked.  It is intended to issue the tender to all the interested parties by 1st June, with all enquiries / questions submitted by mid June and bids in by 13th July 2012.  The Fuel Sub-Group will review the bids and choose 3 shortlisted fuels which will each be run in the M271 classic test by their supplier at one of two designated laboratories.  The successful supplier will be chosen by 7th September, the first batch of ½ million litres will be blended and delivered to the lead laboratory by mid October 2012, ready for testing to commence.
Board Members agreed that the choice of fuel is critical to the test and that all the efforts that are being made to choose the best fuel are well worth the time taken.

TDG-L-106 – Oil Dispersion at Medium Temperature for Passenger Car DI Diesel Engines

Phase 1 repeatability is almost complete.  The draft test method has been produced and statistical analysis will be finalised in time to be presented for acceptance of Phase 1 of the test at the next CEC Board Meeting.  Hardware has already been made available by the OEM to group members.

TDG-L-105 – Low Temperature Pumpability Test

Reference oils samples are being distributed and a Round Robin for Phase 2 reproducibility is ongoing.  Results are expected mid June, in time for presentation of the final Test Method and a request for approval and acceptance of the test by the CEC Management Board at its next meeting.

TDG-L-104 – OM646 Effects of Biodiesel

The Group has reached the conclusion, that it is not possible to develop this test as a combined Piston Cleanliness and Sludge Deposit test. The group has investigated different test cycles, test durations and conditions and concluded that the cycles needed for sludge formation and piston deposits are not compatible.

TDG members have recommended that further development should focus on producing a good Piston Cleanliness test and that Sludge should be a secondary parameter, to be measured if possible.  It is understood that Daimler, VW and Opel have all endorsed this decision.
A task force group has met recently to examine the existing data and to develop a strategic plan for agreement within the TDG.  Further sponsorship funds will need to be agreed to be collected from current sponsors.  The revised plan and financing for the Group will then be forwarded to the CEC Board for approval.

GFC Activities and Future Liaison

Claude Delarue, Technical Co-ordinator of GFC, gave a presentation on behalf of GFC, noting that CEC and GFC are organisations with different ways of working.

GFC proposes that if a CEC Test Method is based on GFC work then the GFC members that actively participated should have free access to the TDG and the CEC Test Method.  CEC works on the basis of equally sharing sponsorship costs once the test reaches CEC, without including the cost of any pre-work and so doesn’t have a model to fund a test development proposed by GFC at the present time.  It was agreed that, should the occasion arise that GFC offered tests to CEC then the Board would look at ways of financing them on a case by case basis.

The CEC Board advised that the Cold Start Driveability test offered by PSA to ACEA, was awaiting further information about reference fuels from PSA for review by ATC and CONCAWE Industry representatives, in order to better understand the problem.  
It was noted that PSA has advised that further in-house work needs to be carried out on its Internal Diesel Injector Deposits Fuels Test, before it can be proposed as a CEC test development.

Board Members thanked GFC for their offer of developing fuels tests in place of CEC and confirmed that this was not currently necessary as CEC is managing its workload efficiently.

Mr Delarue also provided a brief update of GFC’s current activities.

Report from CEC Special Event in November 2011

Board Members have spent some time reviewing the comments of meeting participants and is developing a plan for the future based on 4 main areas of interest.

Status of Test Development for Internal Diesel Injector Deposits (IDID)

The OEM sponsor is experiencing difficulty with repeating previous results that indicated lacquering and has advised that for the time being the test must continue as an internal investigation because it is not yet advanced enough to enter the CEC process.

Oxidation Stability Test

Industry Groups have been comparing data from the Daimler and GFC versions of the test.  
Further discussions about whether CEC should be recommended to develop a biodiesel oxidation test are intended to take place at the next ATC / ATIEL / ACEA meeting.  If the Industry Associations choose to go ahead with this recommendation it is understood that work will first need to be carried out on the Terms of Reference.

TU5 Test

A replacement for CEC L-88-02 TU5 test is currently not required.  It is understood that the test is still running fine, with no issues on the availability of the pistons or other parts until the end of life of the TU5 72 engine, currently advised as end 2014.
Also, by relaxing the referencing protocol of the RL216 (once every 15 candidate tests, instead of every 10 candidate tests, available stocks of RL216 will be conserved until the end of the lifetime of the TU5 72 test.

CEC Secretariat Opening Hours

Normal Opening Hours are Monday to Thursday, 0800-1730 hours.  The CEC Secretariat office is closed on Fridays.
