Definitions
- Unfiltered fuel typically contains various types of contaminants, e.g. Rust particles that have formed by moisture in a fuel tank. If these substances are not removed before the fuel enters the engine, premature wear and defects, for example in the fuel pump and the injection system at the high pressures used there are the result.
- biofuels especially biodiesel
- biodiesel have an increased propensity to form stable water-fuel emulsions compared to conventional fuels, imposing increased demands on the separation of water from biofuels.
- the separation of water has become the focus of development.
- the means for binding the separated water can be achieved in a particularly simple manner that once separated water does not re-enters the fuel, so that an improvement of the separation efficiency of water can be obtained from the fuel.
- This is particularly beneficial for biofuels in which the already separated water has an increased tendency to re-mix with the fuel at the interface between water and fuel.
- the water retention device is arranged in the region of an ittelrohrs associated with the fuel outlet, which supports the filter element and possibly also the coalescing element.
- a filter medium of the filter element eg, a bellows or a wicking filter
- the water retention device is therefore arranged in an advantageous manner on the separate water in the water collection chamber. In this way, the danger is that separated water is contrary to the weight from the water collection chamber through the central tube passes in the direction of fuel outlet, greatly reduced.
- Pure or water-repellent treated fibers or mesh of PTFE (polytetrafluoroethylene), PA (polyamide) or polyester are preferably provided as the hydrophobic material. Such fibers show a particularly high water repellency.
- the coalescing element is followed by a water trap.
- the water trap prevents the coalesced water from escaping to the fuel filter.
- the water trap can do so as a circumferential, annular, vertical or in particular obliquely radially inward to the outflow direction be arranged out of the coalescing element and advantageously have radially circumferential grooves or ribs.
- Already separated or enlarged drops of water remain attached to the water trap, are enlarged by subsequent water and then fall by gravity into the water collection chamber.
- the fuel flows through a flow guide 11 for the separation of water by gravity (third stage).
- the flow velocity and change in direction are selected in a flow section in such a way that the water droplets which are heavier in comparison to the fuel are deflected more strongly and can thus be deposited downwards into the water collection chamber 7.
- the flow guide 11 may be formed, for example, in the form of an annular gap whose outer boundary tion forms the housing 4 and whose diameter is chosen so that the gravity separation is favored.
