The present invention relates to motor fuel compositions comprising at least one diesel fuel of mineral origin and at least one biodiesel fuel, characterized in that the fuel composition contains at least 20% by weight of diesel fuel of mineral origin and 0.05% to 5% by weight of at least one polymer which comprises ester groups and contains repeating units that are derived from ester monomers having 16 to 40 carbon atoms in the alcohol radical, and repeating units that are derived from ester monomers having 7 to 15 carbon atoms in the alcohol radical. The present invention further describes the use of polymers comprising ester groups as flow improvers, and also a process for operating a diesel engine.
La présente invention concerne des compositions de carburants contenant au moins un carburant diesel d'origine minérale et au moins un carburant biodiesel, caractérisées en ce que les compositions de carburants comprennent au moins 20 % en poids de carburant diesel d'origine minérale et de 0,05 à 5 % en poids d'au moins un polymère comprenant des groupements ester, contenant des unités de répétition dérivant de monomères d'ester ayant de 16 à 40 atomes de carbone dans un radical alcool et des unités de répétition dérivant de monomères d'ester ayant de 7 à 15 atomes de carbone dans un radical alcool. La présente invention concerne également l'utilisation de polymères contenant des groupements ester en tant qu'agent favorisant l'écoulement et un procédé de fonctionnement d'un moteur diesel.
