Mechanism for exhausting impurities from engine fuel

摘要

In turbine engine systems liquid diesel fuel (more viscous than gasoline) has heretofore been purged of water impurity and solid impurity by a two stage system comprised of a disposable cartridge type depth filter and a water coalescer. The present invention modifies the conventional system by replacing the disposable cartridge type depth filter with an extended life cyclone; concentrated impurities are vented from the cyclone and coalescer to an additional separator mechanism. This additional separator mechanism returns purified fuel to the fuel tank; separated impurity is exhausted out of the system.
