Patent DE-19807935-C1 (DE)
Inventor: ZUERBIG JUERGEN
IPC: F01N3/20
Filed: 1998-02-25
Granted: 1999-08-26
Abstract: Temperature and volumetric flow rate sensors (5, 4) are directly connected to the reduction control unit (1). These and the NOx sensor (6) are used to determine the quantity of reductant to be injected. There is no recourse to data stored in the engine management system. Dosing of reductant is controlled as a function of the catalyst operational parameters and the exhaust gas composition. Preferred Features: The reductant is urea, supplied from a tank (2) by a pump (3) to the reductant injection valve (7). The reductant controller (1) is built-onto the supply tank (2). As reductant, fuel may be injected (7), the dosing system being connected to the fuel system. A volumetric flow rate sensor is located in the exhaust gas system. Alternatively, a pressure sensor ahead of the reduction catalyst (11, 12) measures exhaust gas pressure, the value being a measure of volumetric flow rate. Differential pressure is alternatively measured across the reduction catalyst, for the same purpose. The reductant controller is directly connected to another exhaust sensor, sensitive to a further component, e.g. NH3 or HC. The NOx sensor (6) has operational temperature-dependent sensitivity to NH3 and/or HC. The controller is also connected to an engine tachometer, used in conjunction with the monitored volumetric flow rate. The tachometer is inductive, relaying information wirelessly to the controller. Its pickup is inductive, self-powered by induction, and floats with respect to vehicle earth. The sensor sensitive to NH3 is located in the reduction catalyst unit. The controller doses sufficient urea to achieve predetermined maximum NH3 and/or predetermined minimal NOx, as indicated by the NOx sensor. The reduction catalyst comprises two or more units in series, the NOx sensor being upstream of the last. The predetermined NH3 or NOx content is a function of the conversion capacity of the catalyst unit following the sensor. Using urea as reductant, the reductant injection valve introduces it into a hydrolysis catalyst, ahead of the reduction catalyst. The urea is injected into the exhaust gas system upstream of the reduction catalyst, hydrolysis being effected in the hot exhaust pipe. The equipment need only be matched to the maximum exhaust throughput and back pressure on the engine, hence obviating measurement on a test stand. The system comes as a self-contained unit for retrofitting or for engines originally developed without NOx-reducing exhaust treatment. The equipment is designed for installation in place of a pre-silencer.

An Independent claim is also included for an arrangement for implementing the method.
Patent DE-19844085-C1 (DE)
Title: Combustion engine control method
Inventor: HARTKE ANDREAS
IPC: F02M26/01
Filed: 1998-09-25
Granted: 2000-03-16
Abstract: The method involves determining an exhaust gas pressure of a cylinder (Z1) during the overlapping of the inlet and outlet valves (30,31) allocated to the cylinder. The determination is dependent on the estimation of exhaust gas pressure caused by the combustion of an air-fuel mixture in the cylinder.  The determination is also dependent on a value, which characterises the effective plane of the valve overlapping. Preferably, the estimation of the exhaust gas pressure depends on the gas mass flow rate in the cylinder.

Granted: 2000-05-31
Abstract: Prevention of hard water deposits by electrolytic production of calcium carbonate seed crystals on brush-like cathodes. The electrolytic production of calcium carbonate seed crystals that attract lime before it can settle out is known practice. The problem is that the crystals depositing on the cathode inactivate it. The cathode is therefore made of spring quality stainless steel in the form of bristles (22) of a round brush. Surrounding these is the anode (21). The function of fixed rods (10) in the anode/cathode gap is to break off crystals from the cathode wires as they are deformed when they pass over the rods when the cathode assembly is rotated. Alternatively a rotating rod assembly could be used with a fixed cathode. Ultrasound could also be used to dislodge crystals. The electrolysis voltage and the frequency of bending of the cathodes determine the quality of the crystals.

Granted: 1996-03-20
Abstract: FIELD: thermal power stations; direct-blow starting of boilers without intermediate pulverized-coal bunker. SUBSTANCE: pulverized-coal system has two series-connected pulverized-coal concentrators 5 and 6; concentrated-mixture connections 7 and 8 are combined to form annular clearance between them; additional burner 10 is inserted in connection 8 along flow direction; connection 7 is joined to main burner 9 of boiler furnace 19. When boiler is started up by means of burner 10, connection 8 is heated to redness and when finely dispersed coal is fed to it, primary combustion occurs and fire spreads to coarsely dispersed fuel in connection 7 when coarsely dispersed pulverized coal is fed to it. Coarse pulverized coal is heated due to burn-out heat of finel pulverized coal releasing combustible gases which ugnite and kindle coke base burning out in main burner 9. Concentrator 6 is swivel chamber with separating member 15 installed at its entrance and made in the form of crosspiece with two connections whose ends are joined with housing. Separating member 15 prevents pulverized fuel rotation about its axis in direction of its motion and aids in its separation against outer walls of housing due to dust separation from flow running about separator 15. Exit section of connection 8 inserted into connection 7 is arranged from bottom upwards with beveled end affording aerodynamic shadow for finely dispersed pulverized fuel flame to prevent its separation. EFFECT: improved design. 1 dwg
