Abstract

The fuel supply unit for a motor vehicle's internal combustion engine has ion exchange means (5) installed inside a chamber charged with fuel. The ion exchange means are constructed for kation and anion exchange. The ion exchange means are for the removal of salts such as calcium carbonate soluble in water components of the fuel. An independent claim is included for a filter in a fuel supply unit, whereby ion exchange means are located inside the filter housing (3) upstream of the filter element (4).

Description

  • The The invention relates to a fuel supply device of a motor vehicle internal combustion engine.
  • In motor vehicle supply devices, which are acted upon with water-containing fuel, in particular an alcohol fuel, in particular calcium carbonate (CaCO 3 ) can be deposited on the walls surrounded by fuel from the water content. In particular, dysfunctionally such deposits can affect the injection system by there can lead to clogging narrow flow cross-sections. This type of water deposits are present in such fine particles that they can not be filtered out by conventional fuel filters. These particles can not be filtered out in conventional fuel filters because they must not be equipped with correspondingly fine-pored filter material to avoid an inadmissibly high pressure loss.
  • Here to create an improvement, that is, deposits of particular Calcium carbonate at fuel-flow wall portions of a fuel supply device with as possible To safely avoid simple means is the problem with which the invention is concerned and that by the formation of a fuel supply device solves the characterizing feature of claim 1.
  • The Invention is based on the general idea that it is through used for example in water treatment in a known manner Ion exchange agent possible is, water deposits such as calcium carbonate to the water to withdraw. It is therefore necessary according to the invention, these known ion exchange agent within a fuel supply device such that fuel flows around these ion exchange means in order to this way of extracting calcium carbonate or the like from the fuel, which is dissolved in water fractions in the fuel. The ion exchange agents should especially in a manner known per se for an equally cationic and anion exchange be formed. Such material is for example available as a product of the Dow Chemical Company under their trade or brand name Dowex MB-50. The composition and mode of action of this ion exchange agent is described, for example, in information of the Dow Chemical Company under the name Form No. 177-01633-1003. This ion exchange agent is just an example of an ion exchange agent which is used effectively according to the invention can. Of course can also other ion exchange agents which have the same effect in the manner for carrying out the he inventive teaching be used. in principle these agents are a kind of regenerable resin. The way in which such means are to regenerate is also known per se and, inter alia, in the aforementioned information of the Dow Chemical Company. Further information on the invention is advantageous usable ion exchange agents contains the information of Dow Chemical Company named Form No. 177-01395-602 QRP.
  • Details for technical information available from the Dow Chemical Company, such as they are quoted above, can be taken from the Internet address, namely http://www.dowex.com
  • A particularly preferred embodiment The invention consists of the ion exchange agent upstream of a Filter material within a in the generic fuel supply device provide provided fuel filter. It already can sufficient, the ion exchange agent in the form of a ring of to allow the filter material flowing around the filter housing to flow around the fuel. Because of the while gradually exhausting the operation of the vehicle engine Ion exchange agent is an arrangement in a fuel filter therefore Particularly advantageous because a fuel filter anyway operating time dependent during the Life of a vehicle engine is replaced. The effective Operating time of an inventively used Ion exchange agent must therefore be used in a filter only be matched to the operating time of the filter. A Arrangement of the ion exchange agent, usually in the form of a Resin is present, upstream of a filter material within the filter assures that particles possibly dissolving from the ion exchange agent, if this one for the engine operation harmful Own size, be separated from the fuel in the filter material.
  • Basically it goes without saying possible, the ion exchange agent of the invention at any point within the generic fuel supply device provided it is only ensured that downstream of the Arrangement of the ion exchange agent no calcium carbonate from in the fuel-containing water can fail more.
  • Important for a good effectiveness of the ion exchange agent is basically one possible large contact area with respect to the fuel to be treated by this means.
  • One particularly advantageous, explained in more detail below embodiment is shown in the drawing.
  • In this shows the only one
  • 1 a fuel line filter half in section, half in view.
  • In the fuel line filter is inside a with opposite provided inflow and outflow channels 1 ; 2 trained filter housing 3 a ring filter element 4 provided, which is flowed through from the radially outside to the inside of the fuel passing through the filter.
  • In one inside the filter housing 3 upstream of the filter element 4 located space is a circular ion exchange agent 5 in the form of a resin known per se in the art. The diameter of the ring-shaped ion exchange agent 5 is only slightly smaller than the inner diameter of the example cylindrically shaped filter housing 1 ,
  • The ring-shaped ion exchange agent shown concretely in the embodiment 5 has approximately the shape of a cup with an open center of the soil. The bottom edge of this cup is distributed over the circumference of webs 6 by far on a closed end disk 7 of the filter element 3 appropriate. The fuel flows through the line filter in the direction of the flow arrows entered in the drawing. Due to a relatively low flow rate at which the fuel flows through the line filter, the fuel has in the vicinity of the ion exchange medium 5 inside the filter housing 3 a relatively long residence time. This long residence time is sufficient to allow the ion exchange agents 5 In the flowing past, water-containing fuel existing substances that can precipitate in the form of calcium carbonate particles, withdraw and integrate into the ion exchange agent.
  • Of course, the ion exchange agents within the filter housing 3 be arranged in any other forms than in a ring shape. Possible shapes are for example star or spiral or helical arrangements and a honeycomb arrangement with a plurality of parallel spaced flow channels is possible. All that matters is that deposits of water contained in the fuel, such as, in particular, calcium carbonate, can be reliably removed by the ion exchange agent used.
  • For the efficiency of an ion exchange agent used according to the invention 5 it is sufficient that is reliably avoided by this a malfunction within the fuel supply device by Wandanlagerungen of water deposits, in particular calcium carbonate. If this is ensured, then it does not matter that calcium carbonate which can be filled, for example, from water fractions is removed virtually completely from the fuel.
  • All in the description and in the following claims Features can be both individually as well as in any form with each other invention essential be.
