V-Motech solutions for meeting RDE regulations

Today more than ever the antipollution RDE regulations established by the environmental authorities are mandatory and hard to achieve.

“To face current and future compulsory constraints imposed on all the automotive sector, our added value consists in developing and providing accurate and reliable tests facilities to conduct emission tests”, explains Stéphane Olevier, C.E.O. of V-Motech.

In concrete terms, V-Motech’s technical skills completes the V-PEMS technology which allows the concentration measurement of five gases, in particular the nitrogen oxides (NOx). Thanks to an exhaust flow meter (Pitot tube device), the flow is indeed established in a formal way, independently if the measures are made on diesel or on gasoline-powered vehicles. “Because we do not compromise with the accuracy of the obtained results, we are able to establish strong and reliable partnerships to assists the development, validation and fulfillment of tests in real conditions as requested by the regulations RDE LDV (Real Driving Emissions for Light Duty Vehicles).” concludes Stéphane Olevier.[image_frame style=”framed_shadow” align=”center” alt=”Results correlation between standard and PEMS measurements” title=”Correlation of results between a standard CO2 measurement and PEMS” height=”259″ width=”650″]https://www.car-engineer.com/wp-content/uploads/2016/10/Results-correlation-between-standard-and-PEMS-measurements.png[/image_frame]

V-Motech is committed to provide accurate and detailed analysis through processing data in accordance with the two methods EMROAD and CLEAR imposed by the RDE LDV regulations.




V-Motech engineering teams are also able to synchronize the measurement of pollutants with external data such as cylinder pressure, consumption, engine control data and CAN vehicle surveys.
