  • Method for cleaning deposits from turbocharger and supercharger compressors
    Patent number: 8858720
    Abstract: A method for removing deposits from at least one compressor powered by an engine. The method comprises disconnecting while the engine is turned off, a high pressure downstream side of the compressor from an intercooler, or an air intake manifold for non-intercooled engines, while leaving the compressor attached to a means used in the engine to drive the compressor. The output airflow is diverted from the compressor away from the engine to a disposal or to a means of separating a cleaning fluid from air. After starting the engine and while the engine is running, the cleaning fluid is injected for a sufficient time to clean the compressor.

  • Low foaming distillate fuel blend
    Publication number: 20060278565
    Abstract: A distillate fuel composition having low foaming characteristics and process for making the composition is described. The composition and process uses Fischer Tropsch distillates to reduce the foaming in distillate fuels. The use of Fischer Tropsch distillates to control foaming in distillate fuels reduces or eliminates the need to use silicon anti-foam agents. A preferred composition comprises at least 20 vol. % of a petroleum derived distillate having a foam vanishing time greater than 20 seconds; and at least 5 vol. % of a Fischer-Tropsch derived distillate having a foam vanishing time of less than 15 seconds; where the resulting distillate fuel blend has a foam vanishing time of 15 seconds or less in the absence of an antifoam additive.
