  • Catalyst subassembly, device comprising same for purifying exhaust gases from an internal combustion engine, modular system for the subassembly, and method for manufacturing the subassembly
    Patent number: 10107162
    Abstract: A catalyst subassembly for a device for purifying exhaust gases from an internal combustion engine, in particular a diesel engine, includes an SCRF catalyst and an SCR catalyst upstream of the SCRF catalyst. The two catalysts are arranged in a common catalyst housing. The catalyst housing, the SCRF catalyst and the SCR catalyst can be selected from a modular system for different variants of the internal combustion engine.

  • Device for the distribution of flowable additives in exhaust gas systems
    Patent number: 8615984
    Abstract: A device is provided for the distribution of flowable additives in exhaust gas systems of an internal combustion engine, in particular for the distribution of a water/urea mixture in an exhaust gas system of a diesel engine, having an injection device in particular opening into the exhaust tract before a so-called SRC catalytic converter, with a swirl generation device being provided for the improvement of the mixing of the exhaust gas with the additive in the introduction region of the additive in the exhaust tract.
