CEC Newsletter - December 2018
This edition will cover feedback of the latest Management Board meetings as well as some news on the test method side, Test Monitoring System (TMS) and the CEC workshop in November.

TDG-F-113 – DISI test

With regards to the fuel test development, the first engine tests performed at the lead lab with non-ethanol containing fuels show promising deposit forming close to the fouling target. In the next steps also ethanol containing fuels shall be tested. There is a remark from the TDG that in case available data show that the initial High Fouling Target is not feasible for ethanol containing fuels, a modification of the original target would have to be considered as an option. However this can only be decided based on the next tests with ethanol containing fuels.The fuel test development shall be finished by the beginning of April 2019.With regards to the injector availability, due to production issues there is a significant delay on the injector supply. The progress in the test development should not be affected by that so far.The next TDG meeting will take place on 12th of February in Ludwigshafen (BASF).

TDG-L-107 – M271 Sludge Test

Good progress has been made recently. With low calibration oil the test does produce sludge within the targeted running time. The oil consumption issue is now fixed and oil consumption is now as expected and ring stick results are also in line with expectations. Repeatability and discrimination have been demonstrated on fuel batch 6. This fuel batch has now been consumed.

The proposal is to blend a new batch. APL will run high and low calibration oils on the new fuel batch to hopefully reconfirm discrimination.

The CEC MB has accepted the TDG to move to Phase 2 on the understanding that:

- APL will run the first two RR tests
- The first test on RL262 to set the test length
- The second test on Oil C to prove discrimination

Once complete and discrimination is confirmed allow continuation of RR

A TDG L-107 meeting was held on 4th December to finalise the plan and appoint the new TDG Chair (see: Chair Appointments TD's).

TDG-T-108 – Pitting Test for Gear Lubricants

During the RR Large, unacceptable scatter of test results and further investigations to find root cause of the scatter were done. It was suspected that FVA 2A has an unstable micro-pitting behaviour at 90°C and is thus not a suitable low reference oil under the standard test conditions (90°C).

An intensive search for new low reference candidate fluids was done and two new candidate fluids have been proposed and initial testing was done with both candidates and CEC RL272 was selected.

For the high reference oil CEC RL273 is a fully formulated finished fluid, designed for dedicated MTF applications.

The results from the second RR were as follows:

- comparable tooth flank condition with typical pitting failure and only (very) limited micro-pitting
- acceptable scattering
- for the high reference oil, there is a questionable result for lab F and it is not clear if this is a possible outlier
- good discrimination between reference fluids

The statistical evaluation shows that there is no statistical valid data for repeatability r due to too few data points it as the testing takes a long time.

In terms of the next steps, the TDG has finalized the work on the draft procedure and has asked the CEC MB for approval.

The CEC MB acknowledged this is really good progress and thanked Thomas Tobie for the excellent leadership work.

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

On the hardware side, ISP has agreed to order 100 engines and 1.000 turbochargers. 20 engines per month will be delivered at ISP. 

The fuel supplier was selected and the first fuel batch has been blended and shipped. There are 8 Round Robin (RR) test runs planned, 4 at each laboratory.

One lab (A) has completed the first RR tests, with results in line with expectation. The TDG meeting scheduled for October was postponed because the other lab (B) could not provide the results on time. Lab A also stopped after the first 2 runs in order to wait for Lab B results of the first two runs. If all results are fine, then a release of the CEC Test Method is expected in Q1 2019.

TDG-L-115 – Low Soot Bearing Wear Test

At its last meeting, the TDG selected IST Prüftechnik as lead lab and confirmed the estimated amount for the test development. The call for sponsors was launched and 11 sponsors are confirmed.

The challenges for the TDG are:

- No low calibration oil available
- Borderline calibration oil – low vis oil
- Phase 2 round robin – test rig costs

The CEC MB suggested the TDG to continue searching for a suitable oil that is within the Terms of Reference.

In case no oils will be available, the CEC MB will look at changing the ToR.

In early 2019 the TDG will have contact with the hardware suppliers, and start in February with the testing.

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

ISP has been selected as the lead lab and 11 sponsors are confirmed.

From the Terms of Reference the first challenge was to collect all information about the test rigs used in the different labs. In order to find this out the group agreed to send out a questionnaire and collect all data about these rigs. The results of the survey showed that all rigs fulfilled the ToR and costs were comparable. The Optimal SRVTM equipment was chosen and is available in 5 labs.

On test parts, the liner material will be supplied by Mahle and the piston rig by federal Mogul.

A minimum of two calibration oils would be needed and there is currently no existing CEC oil suitable. The group is currently looking for oils that have already been tested in the field.  Two oils have already been tested by MAN and they are giving different performance.  These 2 oils are still available and can be used for the test development.

As the test condition of the test rigs are not yet fixed the oils with in-service experience will be needed.

The timeline shows that everything is working according to plan.

SG-L-036 - The Measurement of Lubricants Dynamic Viscosity under High Shear Conditions

The CEC MB has reviewed the effort carried out by the L-036 Surveillance Group to extend the method from 150°C to 100°C.

The CEC MB commended the work done by the SG and supported the suggestion to expand the L-036 method with HTHS testing at 100°C These changes have been implemented in the method.

SG-L-104 & SG-L-099

Following a meeting in October on the availability of the OM646 engines, Daimler is now re-manufacturing [new casings] crankshaft rather than machining the used items as previously planned. The engines will be built in December and sent to the test laboratories. Mid 2019 all Russian supplied hardware will be stopped due to the issue of US embargo on Russian built hardware to the USA. The Daimler lawyers have indicated that they cannot control the supply of these parts beyond their borders and therefore can’t guarantee that parts could not end up in NA. Daimler is looking into two routes to resolve the issue, manufacturing parts in EU and getting signed affidavits from each lab to ensure on the Russian manufactured parts.

SG-L-106 & SG-L-111

The sponsoring OEM will stop producing engines at large scale by the end of 2019. However, the OEM is willing to continue supporting the industry with L-106 and L-111 hardware. It is now up to ACEA to advise how long they will need these tests to be available and inform CEC and the sponsoring OEM accordingly.

SPG on Corrosion

The SPG formed 7 task groups based on the different objectives set in the SPG ToR and all task forces have already made good progress in their work.

There are still several issues to be discussed. Recommendations have been drafted and will be sent to the industry organizations so that they can give their perspectives. CEC needs to have more clarity on what it is what CEC should develop for the industry.

Chair Appointments TDG's

The nomination of Timothy Hadaway as successor to Adrian Fitzpatrick as Chair of TDG-L-107 was endorsed by the Management Board in November.

CEC TMS Updates

New TMS Data Entry Feature
As part of the ongoing improvements to the TMS system, we’ve recently added a new ‘Dependent Variables’ feature. For instance, Instrument ID may be linked to ‘Instrument Model’ or ‘Instrument Manufacturer’. There is no need to re-enter these data once they have been entered the first time.

This will improve accuracy for data entry and will save time. The feature has been rolled out for eleven test types on TMS, with three more under consideration. A note has been placed on the home page for the test types that have been revised.

Continuous Improvement
In the CEC TMS charting system, further changes have been made to selection of graph aspect ratio, font, symbols and resolution.

Also, in data selection, only fluids and batches with control limits to be displayed. There is now an option to limit extreme points on the EWMA to the standard deviation.

A feasibility study is underway to see if we can streamline data entry and evaluate alternative layouts.

Overview of the CEC Management Board Meetings

The latest CEC MB meetings took place on September 25th and November 27th at the CEC offices in Brussels. The following items were decided / discussed:

CEC Chair
Frank Stunnenberg’s position as CEC Chair will end in December 2018 but so far no replacement has been found. The Management Board representatives are still checking within their associations about a potential candidate. 

CEC Website Redesign
Some first meetings have taken place internally and with PDC on the revamp of the CEC Website. A taskforce within the Management Board has been setup to take on this project. More information on the timeline and estimated launch date will be communicated next year.

CEC Workshop

On 28 November 2018, CEC held its second workshop in Brussels. The event was very successful and around 50 participants were present. Very interesting and valuable contributions were given and useful discussions took place.

An update was given on the strategic initiatives that came out of the first workshop in 2016, as well as an overview of the roles & responsibilities of the CEC MB and working groups.

Several breakout sessions were held; in the morning they were organized around product area (fuel tests, lubricant bench tests, transmission tests and lubricants engine tests) and by working group type (TDG, SG, SPG and support groups) in the afternoon.

The presentations of the workshop are available on the website and can be accessed from “My CEC” in the section CEC Information/Presentations/CEC Workshop – 28 November 2018.

In terms of next steps, the CEC Management Board will look at all the input and the feedback received and come up with a proposal on addressing the issues for the coming years.
