R&D projects

Mogano VI (Moteur Gaz Naturel Euro VI)

The project consisted in developing a high power Euro VI gas engine. This project enabled CRMT to develop a know-how in NOx catalysis of the SCR type (residual CH4 residual exhaust) for engines operating in lean mixture.

MOGAS (Moteur Gaz Naturel stationnaire) : a new gas engine technology for generator sets

  • The challenge: to manufacture a 1MW gas engine for emerging countries (Africa & Middle East) subject to severe environmental conditions: high ambient heat, altitude and varying gas quality and a faulty or non-existent electricity network.

CRMT was responsible of several key points:

  • Ensure the power and efficiency of the engine under these excessive conditions,
  • Preserve a low carbon footprint,
  • Perform performance demonstrations by engine tests in the onsite measurement means.

MOGAS was selected by the FUI (Fonds Unique Interministériel) for its innovative content and supported by the CAPENERGIES competitiveness cluster, Bpifrance and the Métropole de Lyon, which partly contributed to its subsidy.

BLUESKY : The Green Mobility accelerator to transform Diesel vehicles into hydrogen and biomethane.

PEMS & CEMS

BLUESKY is a solution for end users such as SMEs of the transport sector, who cannot afford buying too expensive electric vehicles to transform their diesel vehicles. BLUESKY will enable thousands of businesses to comply with the European Green Deal’s clean transportation objectives and will cut down the inevitable long-term reliance of the transport sector on fossil fuels.

The project was recognised by the EU as CRMT was granted the Seal of Excellence for BLUESKY in May 2019.

During last year, CRMT carried out additional work to shift BLUESKY’s development towards a zero-fossil fuel goal favouring the use of hydrogen and biomethane.

BLUESKY kit consists of a Real Drive Control Unit predisposed for the renewable gases and the customer’s duty-cycles of the road transport segment to accelerate the conversion of diesel vehicles into hydrogen and biomethane ones, thus creating a market of affordable vehicles with new technologies and a fast solution to reduce drastically the GHG emissions and pollutants generated by the transport sector.

Experimentation on Liquefied Natural Gas (LNG)

CRMT carried out a study on the environmental and economic qualities of LNG compared to Diesel. The comparative study focused on the emissions of pollutants and the consumption of two Stralis Euro VI tractors:

  • One running on Diesel of 460 hp,
  • The other running on 330 hp of LNG.

The results of the study confirmed the best performance and environmental benefits of LNG over Diesel.

This project was carried out in collaboration with ADEME, the Casino Group, Iveco, Axègaz and the carrier Jacky Perrenot.

NoNOx: Retrofit system for NOx elimination

A single retrofit with NoNOx technology eliminates the equivalent of 15 bus emissions for the city of Grenoble! Composed of a catalyst that removes pollutants from the exhaust gases of CNG buses and a monitoring system that guarantees its smooth operation, NoNOx technology eliminates:

  • 32% of NOx,
  • 60% of HC,
  • 100% of CO

This project was developed by the CRMT in partnership with SEMITAN, INNOV'R, Bpifrance and ADEME, which is partly involved in its financing.

CORTEA: light vehicles and RDE cycles

As part of the CORTEA project (Connaissances, Réduction à la source et Traitement des Emissions dans l’Air), CRMT measures unregulated gaseous pollutants emitted during RDE cycles carried out by Diesel, Gasoline and Natural Gas light vehicles.

 

For this, CRMT is working on the development of an embeddable FTIR (Fourier-Transform Infrared Spectroscopy) analyzer which will make it possible to measure, in addition to regulated pollutants (NO, NO2, CO, CO2, THC, NH3), Volatile Organic Compounds ( VOCs), sulfur compounds, cyclic and aromatic products (toluene, benzene, etc.), formalize, formic acid, etc.

FTIR analyzers are very similar to PEMS, they are compact in size and allow the simultaneous measurement of several components of the engine exhaust gases. They are currently not embeddable in vehicles.

The targeted pollutants are now excluded from the required vehicle certification criteria, and yet are very important to take into account. The results obtained by CRMT will contribute to the definition of new criteria which will be at the origin of tomorrow's automotive standards.

This project is carried out within the framework of CORTEA projects of ADEME, which partly contributes to its financing.

BusOnline: Measurements in real traffic conditions with CEMS technology

Oxides of nitrogen (NOx) and ammonia (NH3) are two of the three main gases that contribute to the phenomenon of acidification of the environment (air, soil, water, vegetation ...).

As part of the BusOnline project, CRMT continuously measured NOx and NH3 emissions emitted by vehicles in real traffic conditions with its CEMS technology.

BusOnline was produced as part of ADEME's AURATRANS projects, which partly contributed to its financing.

PUF : Ultra Fine Particles emitted by heavy vehicles

PUFs are particles of nanometric size (less than 0.1 μm or 100 nanometers in diameter). They are so small that they behave like gases. As part of the PUF project, CRMT was responsible for the development of a measurement system capable of identifying these ultra-fine particles emitted by heavy vehicles.

This project was carried out within the framework of ADEME's AURATRANS projects, which partly contributed to its financing.
