Further, a sensor and a connection element must be mounted on the fuel rail to connect the sensor on the one hand with the fuel rail and on the other hand with a control device. This requires additional work steps in the production. In addition, the sealing point between the sensor and the fuel rail must be reliably formed, over the life of which there is a risk that the sealing point will leak.

Depending on the configuration, the entire sensor may be located in the base body. However, the sensor can also protrude at least partially into the fuel space of the main body. Then at least the sensor connection of the sensor is integrated into the main body.
- the main body has a manifold which is formed of a plastic.
- the fuel cavity is then preferably designed within the distributor tube.
- the fuel can be routed through the manifold and split among the various fuel injectors.
- the fuel can also serve as fuel storage. Specifically, the fuel can be introduced into the fuel as compressed natural gas. While that
- compressed natural gas is then introduced into the fuel space, the
- the fuel distributor thus serves advantageously for distributing natural gas to the fuel injection valves.
- the internal combustion engine can be designed in particular as a diesel or gasoline engine.
- the natural gas is stored here preferably as compressed natural gas in a gas storage, for example at pressures of about 20 MPa (200 bar). Such a compressed natural gas is also called CNG.
- the concept of natural gas is not limited to natural gas but is generally understood.
- the natural gas can also be obtained artificially by coal gasification. Therefore, the term natural gas and natural gas-like fuels to understand.
- the main body can thus be at least partially formed of a plastic.
- the base body and at least partially from a
- Plastic injection be formed.
- the integration of the sensor in the body can be done by the plastic extrusion.
- the sensor can be used as
- Fuel distributor is integrated.
- Fuel space to the fuel valves is feasible to be integrated into the body.
- the outputs may be formed by cups, on which the
- Fuel injection valves are fastened, the cups are integrated into the body. During assembly, inlet ports of the fuel injectors can then be inserted into the cups. The attachment of the fuel injection valves can
- fasteners designed as brackets.
- Such fasteners are preferably attached to the cups, wherein the
- the fuel injection system can be made of a small number of components and assembled in a simple manner.
- the cups may be advantageously formed from a plastic.
- the cups can also be integrated in an advantageous manner in the body.
- the base body can be advantageously stabilized by a plurality of stiffening ribs.
- the sensor can be configured advantageously both as a pressure sensor and as a temperature sensor. In a modified embodiment, however, it is also conceivable that a further sensor is provided with a sensor connection, wherein at least the sensor connection of the further sensor is integrated into the base body. Also conceivable are more than two sensors, if this makes sense in the respective application.
