Abstract: The present disclosure relates to a fuel filter (1) for filtering diesel fuel supplied to an internal combustion engine (2). The fuel filter (1) includes a filter element (12, 19) for trapping and decomposing precipitates suspended in the diesel fuel. An solid acid catalyst like a zeolite is provided for decomposing precipitates trapped by the filter element (12, 19). Sterol glycosides (precipitates) are splitted into sterol and glycoside moieties, which are soluble in the biodiesel, thus preventing clogging of the filter by sterol glycoside agglomerates. The sterol and glycoside moieties pass to the engine where they are burnt. The present disclosure also relates to a method of filtering diesel fuel for supply to an internal combustion engine (2).

Abstract: An auto-drain unit for a compressed gas supply system, comprising: a first, main chamber including a liquid collection reservoir; a second, reference chamber; a discharge valve actuatable to discharge collected liquid from the liquid collection reservoir; a trigger mechanism for actuating the discharge valve; a diaphragm at least in part defining the liquid collection reservoir and the reference chamber, the diaphragm being configured to be movable under the weight of liquid collected in the liquid collection reservoir and operate the trigger mechanism when the weight of collected liquid exceeds a predetermined threshold; and a fluid conduit fluidly connecting the reference chamber to a location in the main chamber above the maximum possible liquid level therein.
