Definitions
- the invention relates to a fuel distributor according to the genus Main claim.
- a fuel distributor is already known from EP-OS 0 374 422, which has a plurality of connecting pieces, into the fuel injection valves one Internal combustion engine can be used, which in turn with fuel from the Fuel distributors are supplied.
- the fuel distributor is made of plastic and has an almost circular, closed fuel channel.
- the Connection pieces are in each case through an opening of the fuel channel in this Connection.
- the largely rigid fuel distributor engages in the Fuel injectors provided clamps that hold the axial Allow fuel injectors.
- A runs parallel to the fuel channel Fuel distributor integrated guide channel, the multiple electrical lines receives. One intervenes for the electrical contacting of the fuel injection valves provided on the electrical lines connector element in a Injector trained connector.
- the guide channel is with one Recording device provided to a receiving portion of a Fuel injector attached connector to which the connector is intended to embrace.
- This construction is complex and cumbersome because of The connector is placed on the outside and mounted on an additional connector must become.
- additional closing plate can be attached to the guide channel, which with a complex hinge can be folded down.
- a fuel injection system for is known from DE-OS 30 10 613 Internal combustion engines that have multiple electromagnetically actuated fuel injectors and a rigid fuel line, the fuel line Has valve receptacles into which the fuel injection valves can be inserted in a sealing manner.
- the fuel line is made up of a fuel distribution line and an overlying one Fuel return line formed.
- Contacting the individual Fuel injectors each have an electrical plug connection, so that Additional contact lines or plug elements and seals are necessary are.
- an electrical connector is provided through which Inserting the fuel injector into the valve holder at the same time the electrical Connection to the electrical connector of the fuel injector can be made.
- This Fuel distributor also includes a fuel supply channel and with the Fuel supply channel connected valve receptacles, in which the Fuel injectors can be used sealingly.
- the electrical contact is made by means of plug-in elements which can be attached laterally to the housing of the fuel injection valves, the via contact lines with parallel to the fuel supply channel extending electrical connecting lines are connected.
- the electrical Connection lines are arranged within a contact strip on the Fuel distributor can be plugged on via a snap connection. This construction is also relatively complex and cumbersome, since the contact strip is separate from the Fuel distributor must be manufactured and the electrical connection lines in one another manufacturing step must be inserted in the contact bar.
