  • OPERATING A TURBO CHARGED DIESEL ENGINE
    Publication number: 20090165760
    Abstract: A method of operating a turbo charged diesel engine is provided where a viscosity increasing component in a diesel fuel composition is used, to improve the acceleration performance, at low engine speeds (for example up to 2200 rpm). This method may be used for reducing the engine speed at which the turbo charger reaches its maximum speed when accelerating at low engine speeds, or reducing the time taken for the turbo charger to reach its maximum speed. It may mitigate a deterioration in the acceleration performance of the engine due to another cause. The VK 40 of the resultant fuel composition is suitably 2.8 mm2/s (centistokes) or greater. The viscosity increasing component may in particular be a Fischer-Tropsch derived fuel component, an oil or a fatty acid alkyl ester. A density increasing component may be used in the fuel composition together with the viscosity increasing component.

  • Diesel fuel compositions
    Publication number: 20030159337
    Abstract: The use of a detergent-containing fuel additive in a diesel fuel composition, for the purpose of reducing engine power loss and/or reversing a previously incurred power loss, and optionally also for reducing smoke and/or particulate emissions. Also provided is a method for assessing the performance of a candidate diesel fuel composition based on its ability to reduce or reverse power loss, and a diesel fuel composition containing a detergent at an active matter concentration of between 100 and 500 ppmw.
