Title: The Commitment of PSA Peugeot-Citroen to Biodiesel Author(s): Alain Delage, Patrice Marez, Francisco Payri, Jean Arregle, Gerald Belot Publication Date: Jul 1998 Summary: For the past decade, rapid diesel engines for passenger cars and light-duty vehicles have made significant progress and are taking an increasing market share in Europe. This situation is resulting from continuous improvement realized in performance, fuel consumption and exhaust emissions. PSA Peugeot-Citroen, who has a leading position on rapid diesel engines, maintains its best efforts to improve and promote this technology by combining advanced research in high pressure direct injection of fuel, combustion chamber efficiency and associated systems, such as exhaust gas recirculation and catalytic post-treatment. Fuel quality improvement is a key issue of this research. It is shown that biofuel (e.g. rapeseed oil methyl ester) when used at 30% and 100% can bring important gains, notably in particulate emissions. Basic studies are conducted on the visualization of pulverization and kinetic combustion of those biodiesel to support pathways for progress. In the field of post-treatment, it is stressed that biofuels display a beneficial effect on DeNox catalysis.
