Management Board

Unconfirmed Minutes from the last Management Board meeting, held on 25th January 2012 are available to CEC Group Members on the CEC Web Site.

New Lubricants Test

A new Gasoline Engine Sludge Protection Test using the M271 EVO engine has been accepted as a new test development in CEC (TDG-L-107).
The Lead Laboratory will be APL.  11 Sponsors have declared themselves.  The first meeting takes place at the end of this month.

New Transmissions Test

A new Pitting Test for Gear Lubricants has been accepted as a new test development in CEC (TDG-T-108). 19 Sponsoring companies have declared their interest in this new test. The first meeting is being planned for end March 2012.

New Fuels Tests Proposed – Cold Start Driveability

The OEM has provided further details to Industry on the proposed ‘Cold Starting Drivability Performance of Fuels, Bio Fuels and Additives’ (using a DV6 Euro 5 Engine).  ACEA, ATC and CONCAWE are currently reviewing the additional data provided and will report back to the next CEC Board Meeting.

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

In 2011, vehicle and fuel injector system manufacturers reported that Internal Diesel Injector Deposits (IDID) were affecting the proper functioning of fuel injectors.  
The primary cause of these deposits was identified as originating primarily from the formation of sodium salts of carboxylates and other anions. Although some cases were observed in Spain, Germany, and Denmark, most of the problems have been found in France, apparently due to the use of a specific type of sodium-containing corrosion inhibitor in French pipelines. Similar problems have been reported in some US regions.

To investigate this problem, a multi-stakeholder IDID Task Force was immediately formed within the European Committee for Standardisation (CEN). This Task Force, reporting to CEN Technical Committee 19, is working to identify the possible sources of sodium in the diesel fuel supply chain and practical approaches to mitigate the IDID problem.

To complement this work, one vehicle manufacturer has already developed a light-duty diesel engine bench test that reproduces the IDID problem observed in the field. This test has been offered to CEC for further development so that it can be used to evaluate fuels and additive technologies. The manufacturer’s results from this bench test are being evaluated now in anticipation of a CEC test development that will most likely begin in the first half of 2012.

Any group or company interested in co-sponsoring this CEC IDID bench test development is asked to contact the CEC Secretariat for more information.

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

The stage 3 matrix of 6 reference tests is ongoing. The results for Viscosity Increase and Piston Merit look promising in terms of test severity.
The EOT soot level was at the lower end of the expected soot range but solutions to improve the EOT soot levels have been proposed for the rest of the planned tests.  It may be that further funding will be required from sponsors and the Group Chairman will be asked to report progress and requirements in time for the next Management Board Meeting.

TDG-L-105 – Low Temperature Pumpability Test

The Group’s work is progressing.  All sponsors have agreed to a set of conditions for the test and targets have been agreed with the SDG Liaison Officer in the Group.  Repeatability tests are running now and a report on Phase 1 data has been submitted to the Management Board for acceptance and permission to move to Phase 2 Reproducibility testing.

TDG-L-104 – OM646 Effects of Biodiesel

The latest test results have led to the conclusion that the engine's oil consumption is dominating the test outcome and therefore the reduction of the engine's oil consumption variation is the main focus for the next steps.

The investigation is being carried out with two used engines that have shown high and low oil consumption. 8 x 24 hrs tests are planned for this investigation. After that a telephone conference call will be held with Group Members and the next step of designing the forced oil consumption strategy will be addressed.
Board Members agreed that this test development has been more difficult than originally thought and whilst it is frustrating that the test is still in an investigation phase, sponsors continue to support its development.  Further sponsor contributions may be required in the future, but have not yet been discussed with Group Members.

Report from CEC Special Event in November 2011

The questions and issues expressed by participants at the CEC Special Event in November have been collated and grouped.  Work has already started on addressing these issues and whilst this is ongoing an initial draft report has been issued to all those that attended the event.

CEC F-23-01 – XUD9 Nozzle Coking Test

It is understood that no further engine blocks are available from the OEM, however blocks can be re-used until the test is no longer required by Industry.  It is likely that the need for this test will continue to diminish.

CEC Secretariat Opening Hours

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