Abstract
An exhaust system (1) for a motor vehicle includes an exhaust gas-purifying device (2) for purifying exhaust gas (3) removed from an internal combustion engine with a reducing agent feed (4), which is arranged downstream and at a spaced location from the exhaust gas-purifying device (2) and by which a reducing agent can be introduced into the exhaust system (1). A reducing agent-deflecting device (7) is arranged between the exhaust gas-purifying device (2) and the reducing agent feed (4). The reducing agent-deflecting device (7) has at least one reducing agent-deflecting element (8) of a blade-like design.
Claims21
An exhaust system for a combustion engine, the exhaust system comprising:
- an exhaust gas-purifying device having an inlet side arranged to receive exhaust gas from the combustion engine, said exhaust gas-purifying device having an outlet side arranged to discharge the exhaust gas from said exhaust gas-purifying device, said exhaust gas-purifying device having a passage to guide the exhaust gas from said inlet side to said outlet side, a surface of said passage having a material to purify the exhaust gas;
- an injection area connected to said outlet side of said exhaust gas-purifying device and receiving the exhaust gas from said exhaust gas-purifying device;
- a reducing agent feed mounted in said injection area and configured to introduce reducing agent into said injection area in a feed direction and with a feed range, said feed direction being opposite to a direction of the exhaust gas through said injection area, said material of said exhaust gas-purifying device being arranged in said feed direction and said feed range;
- a deflecting device arranged between the exhaust gas-purifying device and said reducing agent feed, said deflecting device being arranged to block the reducing agent from contacting said material of said exhaust gas-purifying device.

An exhaust system for a combustion engine, the exhaust system comprising:
- an exhaust gas-purifying means for purifying exhaust gas removed from the combustion engine;
- a reducing agent feed means for introducing a reducing agent into the exhaust system, said reducing agent feed means being located at a spaced location downstream from said exhaust gas-purifying means, said reducing agent feed means being arranged with respect to said exhaust gas-purifying means to feed the reducing agent in a direction toward said exhaust gas-purifying means;
- a reducing agent-deflecting device arranged between said exhaust gas-purifying means and said reducing agent feed means, said reducing agent-deflecting device having a reducing agent-deflecting element, said deflecting device being arranged to prevent the reducing agent from contacting said exhaust gas-purifying means, said deflecting device being arranged to form a line of sight blocking for a majority of reducing agent introduced by said reducing agent feed means with a feed direction and a feed range to contact said material of said exhaust gas-purifying means.
A motor vehicle comprising:
- an internal combustion engine;
- and
- an exhaust system, the internal combustion engine being arranged upstream of the exhaust system and fluidically connected with the exhaust system, the exhaust system comprising:
- an exhaust gas-purifying means for purifying exhaust gas removed from the internal combustion engine of the motor vehicle;
- a reducing agent feed means for introducing reducing agent into the exhaust system, the reducing agent feed means being located at a spaced location downstream from the exhaust gas-purifying means, said reducing agent feed means being arranged with respect to said exhaust gas-purifying means and being adapted to feed the reducing agent in a direction of propagation toward said exhaust gas-purifying means;
- and
- a reducing agent-deflecting device arranged between the exhaust gas-purifying means and the reducing agent feed means, the reducing agent-deflecting device having at least one reducing agent-deflecting element with a blade design, the reducing agent-deflecting device comprising a plurality of reducing agent-deflecting elements connected to the gas-purifying means and arranged in an area of an outlet side of the exhaust gas-purifying means, the reducing agent-deflecting elements providing a line of sight blocking of the reducing agent with respect to the direction of propagation of the reducing agent, the reducing agent-deflecting elements being arranged each at spaced locations from one another on a respective fastening element whereby a grid of reducing agent-deflecting elements is formed by the reducing agent-deflecting elements, said deflecting device and said reducing agent feed means being arranged to block the reducing agent from contacting said exhaust gas-purifying means.
