Device generating exhaust gas, especially a boat, comprising a system for determining the volume of exhaust gas

摘要

A device for generating exhaust gas including a exhaust gas channel and a system. The system includes: a plurality of Bragg gratings distributed in positions transversely to the direction of flow of an exhaust gas at the end of the exhaust gas channel; an optical wave guide structure includes at least one optical wave guide and the Bragg gratings; and a heating device arranged adjacently to the Bragg gratings and through which the Bragg gratings are subjected to heat, or a cooling device arranged adjacently to the Bragg gratings, through which the Bragg gratings can be subjected to cold. The optical wave guide structure and the heating device or the cooling device are arranged at the end of the exhaust gas channel at a distance from an outlet of the exhaust gas into the surroundings of the device.

主权项

1. A device generating exhaust gas, comprising:
an exhaust gas channel from which exhaust gas leaves the device into the surroundings of the device; and a system configured to determine an exhaust gas volume discharged through the exhaust gas channel to the surroundings, the system including
a plurality of Bragg gratings distributed in positions transversely to a flow direction of the exhaust gas at an end of the exhaust gas channel, andan optical wave guide structure in which the Bragg gratings are embodied, the optical wave guide structure including at least one optical wave guide, anda heating device, arranged adjacently to the Bragg gratings and by which the Bragg gratings are subjected to heat, wherein a thermal output to be emitted by the heating device is adjustable to the exhaust gas temperature, or a cooling device arranged adjacently to the Bragg gratings and by which the Bragg gratings are coolable to a temperature below an exhaust gas temperature, wherein the optical wave guide structure and the heating or cooling device are arranged in an interior of the exhaust gas channel at the end of the exhaust gas channel at a distance from an outlet of the exhaust gas into the surroundings of the device, wherein the following applies of the distance (d): d>D/10, where d is the distance (d) from the outlet and D is the diameter of the outlet.
