A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.

The present invention relates to a device for transferring exhaust gas between a front and rear carriage of a mobile working machine, in particular a dump truck, separated by an articulated pivot joint, which working machine has a pipe section, which is variable in it length, for conducting exhaust gas, a first flexible hose cooperating with a first end portion of the pipe section for introducing exhaust gas into the pipe section, and a second flexible hose cooperating with a second end portion of the pipe section for discharging exhaust gas from the pipe section. The device is characterized in that a first cardan shaft is provided in the first end portion, the distal end of which is configured to be rigidly attached to a fastening section of the front carriage or the rear carriage of the working machine, and a second cardan shaft is provided in the second end region.

A line connector having a connector piece with at least one junction portion for junction connection to a media line or to an assembly, a transitional portion contiguous to the junction portion, and a flow duct. In at least the region of the transitional portion, an electrical heating element for the media line is provided in an arrangement at least partially surrounding the flow duct. The connector piece, together with the heating element, is surrounded by an outer cladding. At least one of the junction portions is designed as a hollow, cylindrical receptacle for directly plugging in the end of the media line, the media line being capable of being fastened in a materially integral manner. The junction portion including, at least in regions, a material transparent to laser beams in such a way that the media line can be fastened by way of laser welding.
