Engine fuels technical committee - Methods

relations between GFC-CTCM and CEC

The CEC (Coordinating European Council) represents the motor, oil, petroleum additive and allied industries in the development of performance tests for the evaluation and homologation of petroleum products. It works on the basis of tenders and is financed by members. The GFC has kept an approach of corporate sharing of activities and is being complementary to CEC and not a competitor. In fact, reference fuels defined by CEC PF-017 working group are used in many standard tests for fuels or lubricants as well as for vehicle homologation in line with European directives (with regards to fuel consumption, power, regulated exhaust emissions and losses by evaporation).

The industries in CTCM

Members of industries participating in CTCM today belong to four large categories: oil companies, car manufacturers, additive manufacturers and test laboratories.

The companies regularly represented in CTCM are:

• ETHYL,
• ETS,
• EXXON-MOBIL,
• I.S.P.,
• l’INSTITUT FRANCAIS DU PETROLE (ifp),
• la MARINE NATIONALE (SECLF),
• la SNCF,
• le DCSEA (Service des ESSENCES des ARMEES),
• le MOTEUR MODERNE,
• LUBRIZOL,
• OCTEL,
• PSA-PEUGEOT-CITROEN,
• RENAULT TRUCK,
• RENAULT,
• ROBERT BOSCH,
• TOTAL FRANCE
• …

Examples of research by the CTCM

The latest work of the CTCM dealt with the following topics:

The impact of petrol volatility on cold and hot driveability.

Evaluation test methods have been developed by the CM-1 working group whose research has been included in an in-depth study (over 250 test vehicles on roller benches) by CONCAWE (CONservation of Clean Air and Water in Europe), a consortium dealing with environmental research concerning the petroleum industry.

CM-6 Evaluation od the cold start driveability of Diesel engines:   Pilote by Gérald Crépeau – PSA Peugeot Citroën

The constraints of emissions of the pollutants associated with the necessary fuel consumption decrease involve an increase in the problems of the cold start driveability. The target of this group is the creation of a methodology related to these problems for proposal for a method on the level of the CEC.

Investigation groups (2010)

CM-7.1 Low temperature stability of the Diesel fuels
Pilote Gérald Crépeau – PSA Peugeot Citroën

 

Due to presence of BioDiesel, it is to find a method to evaluate stabilities at low temperature (ie ambiant temperature in the tanks).

 

CM-7.2 Efficience of the antioxidant additives

 

It is a question of developing a new methodology making it possible to determine the efficience of an antioxidant additive compared to another and the BHT reference. AGQM proposed an evaluation on the principle the principle of the test rancimat. The industry of the additiveurs not thinking that is sufficient, we have opened a group of investigation in order to write a methodology allowing to better put forward the
effectiveness of the antioxidant additives. A procedure including a measurement of the sediments developed by the SWRI for the B5/B10 is looked at.

 

CM-8 Characterization of the harmlessness of the additives with respect to the pipelines

 

The additives suppliers would wish to set up a procedure laboratory allowing to validate the harmlessness of their products with respect to the distribution in pipelines. The opinion of the refiners and the distributers being required, Trapil could be invited to see how they position on this subject. The IFP working on the transport of the oil products and CETIM being expert in the phenomena of corrosion, the CTCM has competences to answer this challenge.
