CEC Newsletter - July 2018
In this edition, we will cover feedback of the latest Management Board meeting as well as some news on the test method side and the office move of the CEC Secretariat.

TDG-F-113 – DISI test

The test has been installed and is running at ISP. The initial validation runs are complete and conclusive when compared with original OEMs indications. There is a draft test method for Keep Clean but not for Clean Up. The test operating conditions have been aligned between all labs currently running the test.

One major issue concerns the impossibility to identify a suitable EN228 high fouling with the existing hardware.

The only fuel showing the expected fouling level on the ISP installation is not EN228 compliant. Other labs have also run the test and the only engine showing high fouling with EN228 fuel is a different engine type.

The TDG held a meeting on 11th April during which a 4-step action plan was set up. The 1st step consisted in CAF sourcing a further batch of severe fuel from a local Czech refinery. This batch was delivered but gave insufficient fouling. CAF also informed that the most severe Cz E0 market fuel is not available anymore. Following this, it was decided to review the action and propose new steps.

- CAF now works on a new timeline for EN228 high fouling fuel investigation, supply and testing and will present the first results for the next plenary meeting on 13th September.

- The task force initiated in April will continue to investigate setting differences between BLG and CAVE engines.

- ISP will repeat the last test run with Severe Cz E0 Fuel replicate from CAF, using a different type of injectors (CAVE instead of BLG) to check possible hardware effect on engine response.

The next TDG meeting will take place on 13th September.

Timewise, it is expected that there will be a one year delay.

TDG-L-107 – M271 Sludge Test

The group did some work to determine the oil consumption and needed to change some test conditions. Haltermann produced a new fuel batch and the first test on this new fuel batch to a modified test procedure has started. Test is going on at APL and is half way through. 

The new test procedure should reduce oil consumption and allow the engine to get to end of test (EOT). This first test is on the low reference oil and should give an average engine sludge rating of 8.6 +/- 0.2 at around 275 to 300 hours. 

A face-to-face meeting is being organized around the 16th of July to coincide with the EOT ratings being available for the group to discuss next steps which if successful, will likely be a repeat. At this time the current TDG plan is still applicable.

TDG-T-108 - Pitting test

Following the last TDG meeting that took place on April 9th the group has run the RR testing and has statistical results, and had two options to continue where they needed advice on:

1) Doing further testing to establish r-values. This would require that several labs perform two complete tests with each of the candidate fluids (2x3 test runs for each fluid).

This option would give the required information but seems to be not very effective - assuming an average running time of approx. 2 weeks per single run the required testing capacity in each lab is some 6 months only for these tests (if enough testing capacity within a limited time would be available seems to be questionable, it is assumed that it will take at least one year to collect enough data!!). 

2) Another option that was discussed, is to publish the test procedure and to close the group, establishing at the same time a regular SG and to collect the required further test results based on a limited number and frequency of reference runs to define r-values. Group members would be in favour of this option and the group´s SDG will discuss the requirements also within the next meeting of SDG-group in May. 

The Management Board supported the 2nd option with the provision that the SDG-group endorses this option also.

TDG-L-114 - Toyota Diesel Turbocharger Compressor Deposit test proposal 

The first engine will be shipped from ISP to APL beginning of week 26. So far the test kit is tested at ISP and complete. 

The group is currently 10 weeks behind the schedule. But there are still chances to finish the test development in time, since just two labs are participating in the round robin. The total test duration of each round robin phase is between 4 and 6 weeks, therefore, the first results could be available in August, and then the following in September and October. 

Total won the tender. The reference fuel name is CEC DF-99-18.

TDG-L-115 – Low Soot Bearing Wear Test

TDG-L-115 was setup and an inaugural meeting took place on May 9th via conference call and Ralf Meyke has been confirmed as the Chair. The TDG agreed on the ToR and on the drafted roadmap. A list of potential test rig suppliers was prepared. A questionnaire on test rig specification was sent out to potential suppliers and the next F2F meeting is planned for 25th July. 

TDG-L-116 – Low Soot Ring Liner Wear Test

TDG-L-116 was setup and an inaugural meeting took place on May 18th via conference call and Udo Böcker has been confirmed as the Chair. A survey was sent out to the TDG member asking which friction rigs are known and who has installed them in their labs. Based on the survey results, the list of rig suppliers and labs that currently have the rig available will be prepared. Some ACEA members, MAN, DAF and IVECO, have joined both TDG-115 and TDG-116  as experts. The next F2F meeting is planned for 26th July.


The SG-F-110 method, a fuels test for IDID, has been suffering from precision issues since late 2016 / early 2017. Since that time the SG has been trying to improve the test precision by various initiatives. The main initiative was to improve the clarity and detail of the fuel blending method (fuel plus contaminants) which was identified as a potential source of significant variability between test laboratories and the test is known to be very sensitive to the fuel blending procedure. A round robin has been conducted (late 2017 / early 2018).

The group had a meeting on 8th May during which it was agreed to declare the test out of control. Because of the current test precision, the test is not fit for its intended purpose and should not be used as an industry standard test until this is rectified or the test objectives are redefined.

The CEC working group members recommend that the test is returned to development status and they will continue to support and investigate the issue, to develop an acceptable CEC test. 

The group recently held a conference call to discuss the results of the latest round robin which showed that the injectors were affected very similarly by IDID. The group has requested to go back to the TDG phase which the Management Board accepted. 

The TDG will no longer run test until they have identified the issue. The group will do more analyses. If the results are successful, then the TDG would ask the Management Board to go back to SG.


The group has a meeting on April 10th. Two years ago they were having trouble with spare parts, reference oils, and reference parts. They showed good progress and are continuing working on identification of reference fluids. The high reference oil is not yet stable, and they are still doing RR testing with some of the reference parts but this this group is steadily getting back on track.

Chairmen Appointments SG’s

The nomination of Ms. Selin Manukyen as successor to Mr. Helmut Melchior as Chair of SG-T-045 was endorsed by the Management Board in May.

The nomination of Mr. Clive Dunn as (Vice) Chairman of SG-T-084 as successor to Mr. Feuchter was endorsed by the Management Board in May as well as the nomination of Mr. Robert Belcher as Secretary as successor of Mr. Dunn.

CEC TMS Update

CEC TMS Data Entry
Further improvements are being made to data entry on TMS. This will simplify data entry for certain fields that depend on other values. For instance, instrument manufacturer is linked instrument ID. There is no need to re-enter these data once the first entry has been made. This will save time for participating laboratories and improve accuracy of results. 

The new data entry method is currently being trialed on KO (CEC-L-014) and KRL (CEC-T-045), and will be rolled out to all test types on CEC TMS in due course.

Overview of the CEC Management Board Meeting on June 19th, 2018

The latest CEC MB meeting took place on June 19th at the CEC offices in Brussels. The following items were decided/discussed:

CEC Chairmanship
Frank Stunnenberg’s Chairmanship will end in December 2018 and following the rotational system as described in the Articles, next in line is either CONCAWE or ACEA. The Management Board representatives will check within their associations about a potential candidate.

CEC Website Redesign
For the coming year we had planned a revamp of the CEC Website, due to some delays this will be continued for 2019. 

CEC Strategic Items
Several strategic issues were identified in a strategic session in 2015 and the plans for each of these were presented in the first workshop in 2016. Some of these issues are still active but most of them are almost completed. A summary of the specific actions and an overview of the activities that have been done is being prepared and will be presented at the workshop in November.
