Interview with Gilles Le Borgne, Director of Research & Development, PSA Peugeot Citroën ›› WE WOULD LIKE EVERYONE TO OWN A CLEAN VEHICLE ‹‹ 5 F O C U S Photos: PSA PEUGEOT CITRÖEN ‹F›: Experts agree that the internal combustion engine will be the prime mover for passenger cars for many years to come. PSA recently presented the PureTech engine family with many innovations. Can you tell us more about it? ‹Gilles Le Borgne›: In order to fulfill PSA’s strong commitment to reduce its European fleet’s CO2 emissions to 95g/km by 2020, PSA has developed a new modular family of 3-cylinder engines. This PureTech family, composed of 1.0 l and 1.2 l naturally aspirated PFI engines and 1.2 l Turbocharged Direct Injection engines, covers the power range from 50 kW to 96 kW. The new Turbo PureTech engine, by means of significant technological breakthroughs, provides outstanding performance and fun to drive coupled with dramatically reduced CO2 emissions. It achieves this whilst preserving a high level of components and industrial commonality with the naturally aspirated versions. A remarkable property of this engine, among others, is that it features low BSFC operating range of less than 240 g/Kwh ensuring robust fuel saving within a wide range of driving profiles. The new 3-cylinder PureTech modular family, which definitively ranks PSA Peugeot Citroën as a best-inclass CO2 player, constitutes an ideal technological basis for future worldwide developments matching future regulation requirements and customer expectations. ‹F›: In Europe the diesel engine is very successful, despite the emission legislation becoming stricter. Can you tell us more about the BlueHDi diesel engine and the ways that you fulfilled the EURO 6 emission legislation with this engine? ‹Gilles Le Borgne›: In 2013, new emissions control technology was launched for diesel engines: the Blue HDi exhaust line. Previewed at Innovation Day, this new pollutant emission treatment system incorporates selective catalytic reduction, positioned upstream from the diesel particulate filter. This is made possible by the particle additive filter developed by PSA Peugeot Citroën and launched in a world first in 2000. The Blue HDi line meets the future Euro 6 standard and brings diesel emissions down to petrol levels, while reducing CO2 emissions by 2 to 4 %. The Group decided to deploy this technology throughout the entire Diesel Euro 6 range, posting remarkable CO2 emission levels such as 94 g on Citroën C4 Picasso and 82g on Peugeot 308 “Car of the year”. ‹F›: PSA Peugeot Citroën was a pioneer with the FAP particle filter system. Do you think that the more complex exhaust gas after-treatment systems necessary for EURO 6 will reduce the sales numbers of cars with diesel engines, especially in the small car segment?
