MOTOR FUEL COMPOSITIONS COMPRISING RENEWABLE RAW MATERIALS

摘要

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 o f 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 t o 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.
