CEC Newsletter March 2014
CEC Newsletter March 2014

This Newsletter is based on information received and discussed at the CEC Management Board Meeting on 18th and 19th March 2014.  Please note that it may have been superseded by further events that have occurred between the meeting and the publication of this Newsletter.


Management Board

Unconfirmed Minutes from the last Management Board meeting, held on 18th and19th March 2014 are available to CEC Group Members on the CEC Web Site.


Improvements to Test Development Process

Board discussions resulted in improvements which will be introduced in the near future.
These include the individual tailoring of TDG Progress reports, the allocation of a Management Board representative earlier in the process of TDG’s, the upgrading of Guidelines for Chairmen and Secretaries, for Terms of Reference and for CEC Special Project Groups.


Statistics Procedures

The revised Statistics Procedures have been approved and published as part of the CEC Constitution.
The SDG amendments to Guideline 18 were also approved and will be re-published once other amendments have been finalized.


TDG-L-104 – OM646 Effects of Biodiesel

A delay is expected in setting up Phase 2 due to problems with the EVO engine blocks, although the  next batch of engines is expected to be available from Daimler in August 2014.  The existing blocks are being used to keep the CEC L-099-08 test running.  As things stand at the moment Phase 2 Reproducibility, it should still be possible to complete this test development   in time for the 2014 ACEA Sequences.


TDG-L-106 – Oil Dispersion at Medium Temperature for Passenger Car DI Diesel Engines (DV6)

Further data is expected from participants in the Round Robin so it was agreed to defer a decision on test acceptance for Viscosity Increase until this data is available.  This should ensure full confidence in the data provided without jeopardizing the availability of the test for the next ACEA sequences.


TDG-L-107 – M271 Sludge Test

A severity change was necessary and the Group decided not to change the test procedure but to change  the severity of the fuel.   Current indications are that the fuel reformulation has been effective and that the test development is progressing according to plan again.


TDG-T-108 – Pitting Test

Drafts of the main sections of the Test Procedure will be discussed at the next group meeting in March 2014.
Repeatability data is expected to be presented to the CEC Board in May and approval obtained for the Group to move to Phase 2 Reproducibility testing and the setting up of a Round Robin.


TDG-L-109 Oxidation Test

The CEC Board accepted the data presented by the Chairmen of TDG-L-109, Udo Boecker, and agreed to the group proceeding to Phase 2 Reproducibility.
The Results from the Round Robin (with up to 10 laboratories participating) are expected in September 2014. Remaining sponsorship funds will be returned  in equal parts to all the original sponsors.


TDG-F-110 IDID Test

There are some concerns about the levels of contaminants being used  to produce the deposits in this test as well as discrimination issues between fuels.  The Board Member supporting this Group will be discussing these issues at the Group’s next meeting


TDG-L-111 - Gasoline Cleanliness Test

A repeat test on the reformulated  low calibration oil LC2 is currently running with results available soon.


CEC Surveillance Groups

The Management Board has endorsed the appointments of Daniel Burton and David Weissenberger as Chairmen of SG-F-023 and SG-F -005 respectively.


CEC Tests Life Plan

This was reviewed by the Board with a concern raised on behalf of CONCAWE, about the future of CEC fuels tests, specifically with reference to the availability of parts and the continuing use of old technology.
ACEA is being made aware of these concerns.


SG-L-039 Elastomers

It was noted that on 6th February 2014, RE4 Elastomer testing as referenced in the CEC-L-39-96 test method and ACEA sequences was temporarily suspended due to a manufacturing problem.
A proposal has been made to ACEA to consider issuing an official note stating that RE4 is no longer required as it is at the end of its life.  A new TDG with new elastomer materials is likely to be recommended by the CEC Special Project Group on Elastomers.


SG-L-088 – TU5

The successor test TDG-L-111 will not be ready by the end of the year when hardware is expected to run out.  The Chairman will discuss with PCM the possibility of extending hardware availability to the end of the 2nd quarter 2015 possibly by re-furbishing and re-using cylinder heads.


SG-L-093 – DV4

The test is being carefully managed to ensure its availability until the end of 2014, when its successor test using the DV6 engine should be ready for inclusion into the 2014 ACEA Sequences.  Restrictions are in place for the use of reference oils and the referencing frequency has been relaxed. Fuel will be available until early April.


SG-L-099 OM646 Wear Test

The engine blocks that Daimler has confirmed are within specification will only be used to maintain CEC L-99-08 (OM646 Wear) test.  ACEA will advise CEC after their meeting in March if any further action is required.
