Problems solved by technology

[0003] The injector assembly known from document DE 10 2010 064 115 A1 has the disadvantage that the production of the fuel distributor strip from aluminum or stainless steel is uneconomical to manufacture precisely for relatively large product volumes
In addition, the seal between the sensor and the fuel distributor rail must be designed reliably, wherein there is a risk of the seal becoming leaky over the service life

Embodiment Construction

[0016] figure 1 A fuel injection system 1 with a fuel distributor 2 and a plurality of fuel injection valves 3 , 4 is shown in a perspective view according to an exemplary embodiment of the invention. The fuel distributor 2 is especially suitable for distributing natural gas, in particular CNG (compressed natural gas), to the fuel injection valves 3 , 4 . However, the fuel dispenser 2 can also be used for dispensing other fuels. Accordingly, the fuel injection system 1 is particularly suitable for the intake manifold injection of natural gas in internal combustion engines. However, the fuel injection system 1 according to the invention is also suitable for other applications.

[0017] The fuel distributor 2 has a base body 5 with a distributor tube 6 . Furthermore, a sensor 7 with a sensor interface 8 is provided. At least the sensor interface 8 of the sensor 7 is integrated in the base body 5 . The sensor connection 8 is thus connected to the distributor tube 6 . In thi...

Abstract

The invention relates to a fuel distributor (2), which is used to distribute natural gas to a plurality of fuel injection valves (3, 4). A main body (5), in which a fuel chamber (9) is provided, and a plurality of cups (11, 12), by means of which the fuel can be conducted from the fuel chamber (9) to the fuel injection valves (3, 4), are provided. In addition, the fuel distributor (2) comprises a sensor (7) having a sensor connection (8), wherein the sensor connection (8) of the sensor (7) is integrated in the main body (5). The invention further relates to a fuel injection system (1) having such a fuel distributor (2).

Description

technical field [0001] The invention relates to a fuel distributor for distributing fuel to a plurality of fuel injection valves and to a fuel injection system having such a combustion distributor and a plurality of fuel injection valves. The invention relates in particular to a fuel injection system for injecting natural gas, in particular intake manifold injection, in an internal combustion engine. Background technique [0002] From DE 10 2010 064 115 A1 an injector assembly for a fuel injection system of a hybrid-tight externally ignited internal combustion engine is known. The known injector assembly comprises a fuel distributor rail, a corresponding holder and an injection valve. The fuel distributor strip is used to distribute compressed natural gas to the injection valves. In addition, sensors are mounted on the fuel distribution rail, which sensors serve, for example, to measure the pressure and temperature of the natural gas in the fuel distribution rail. [0003...
