Abstract: A method and system for freeze protecting liquid NOx reductants, preferably used in vehicle applications, wherein a liquid NOx reductant, carried onboard a vehicle exposed to cold weather conditions, is heated by existing thermal energy generated by fuel compression. The heated fuel heats a potentially frozen reductant and the liquid reductant is supplied to an exhaust gas pipe in front of a catalyst for reducing NOx on the surface of the catalyst and catalytically converted into environmentally safe nitrogen and water.

Abstract: A fuel additive dosing method and system for adding additive to fuel in a vehicle monitors the fuel added into the fuel tank of the vehicle by using an onboard flow measuring device such as a turbine, a venturi, a rotary meter, or a thermal flow meter located at the inlet of the fuel tank. The fuel added into the fuel tank may also be monitored by receiving a signal indicative of the fuel added into the fuel tank from a fuel pump pumping the fuel into the fuel tank to the vehicle. The method and system use an electronic control unit (ECU) of the vehicle to monitor fuel consumption. The direct approaches for monitoring the fuel added to the vehicle in conjunction with monitoring fuel consumption enables the method and system to add a proper amount of additive to the fuel to maintain a desired fuel/additive ratio in the vehicle.

Abstract: A filter arrangement for removal of soot particles from the exhaust gases of an internal combustion engine, including a current supply and a filter body. The filter body is composed of a porous filter material. The filter body has a plurality of filter ducts arranged in a honey-comb pattern. Each filter duct has an inlet opening for the intake of the exhaust gases. The filter arrangement further includes a resistance heating element arranged in a region of each inlet opening and having a series of loops each projecting into the filter ducts. The resistance heating element further has a lead-in line and a lead-out line connected to the current supply. A wall of a respective filter duct and a respective heating element loop are form lockingly connected together.
