Patent DE-4422072-A1 (DE)
Title: Device for controlling the air/fuel ratio of an internal combustion engine
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1994-06-23
Abstract: In order to control an air/fuel ratio in a stable way without control oscillations, an initial state of a fuel/air ratio sensor (M3) is monitored in order to decide whether a modern or progressive control using a dynamic model can be used (M6). The suitability for use of the dynamic model can be determined in that it is monitored whether the initial value of an air/fuel ratio sensor (M3) lies in a predetermined range or whether the air/fuel ratio sensor is kept stably in a state which permits an air/fuel ratio to be detected. If the initial state of the sensor lies outside the range suitable for the modern control, the system is switched over from an optimum feedback amplification (IKn) for carrying out the modern control to a lower amplification (IKn'), or the modern control is switched over to the normal control by means of proportional and integral control. By means of this switching over of control operating modes the most suitable air/fuel ratio control can be carried out. <IMAGE>
Patent DE-4425968-A1 (DE)
Inventor: LUEDER THOMAS DR
IPC: C11D11/04
Filed: 1994-07-25
Abstract: The invention concerns low dust content surfactant granulates which have increased bulk density but nevertheless dissolve well in water. These granulates can be prepared by a process in which an anionic surfactant or a plurality of anionic surfactants in its/their acid form and a highly-concentrated aqueous alkaline component are acted upon separately by a gaseous medium, are combined, neutralized in a multi-substance nozzle and, under high propellant pressure, are sprayed in a drying tower. The acid and alkaline components are combined in almost stoechiometric amounts and the resultant solid, finely particulate products are conveyed to a mechanical mixer in which the fine particles are agglomerated to form granulates having a bulk density of at least 400 g/l.

Title: Circuit arrangement for blocking output signals
Inventor: FINSTERBUSCH ROLF DIPL ING
IPC: H03K19/003
Filed: 1994-07-28
Abstract: The output signals from the arrangement of logic circuits are carried over a series connected component (B). The component connects operating voltage-free output signals from the group of logic circuits to processing devices independently of the magnitude (UB) of the operating voltage. The component only connects output signals near to the operating voltage to the processing devices until the operating voltage threshold is reached and is otherwise connected at its output operating voltage-free. In one embodiment two consecutive arrangements of logic circuits are fed from separate sources for their respective operating voltages.

Patent DE-4440833-A1 (DE)
Title: Catalysts and reducing agent injection system preventing emission of nitrogen oxide(s) from lean burning diesel engine
Inventor: SCHENKERMAYR GUENTER
IPC: B01D53/94
Filed: 1994-11-15
Abstract: The exhaust gases from an engine, esp. a diesel engine, have a residual oxygen content. A dosing device first injects a reducing agent. The gases proceed to catalysts, spaced out in te exhaust flow direction. these have temperature dependent conversion abilities. Oxidising and reducing catalysts (3,4), suitable for strongly varying exhaust gas entrance temperatures (T3,T4) are used. Dosing devices (5,6) are allocated to them, having varied construction and volumetric flow-rates, and independent control. A catalyst for high flow-rate (3), of the start-up variety, is located near to the combustion chambers.  To reduce NOx emissions from lean burning diesel engines, optimising over the entire working range of the engine.  The system improves on prior art by providing optimal destruction of the polluting compounds, for each point on the load curve, and also accommodates to the changing temperatures of warm-up. Separate injection before each catalyst optimises the conversion along the path of the exhaust gas flow. Injection into the combustion chamber has the advantage that the reducing agent (fuel) is well mixed and vapourised, and commences reaction early, arriving in the ideal state at the catalyst. The fuel injectors conveniently double as the reducing agent injectors.

Title: Electromagnetically operated fuel-injection valve
Inventor: KRAUSS RUDOLF
IPC: F02M51/08
Filed: 1990-05-25
Abstract: The invention concerns an electromagnetically operated fuel-injection valve (1) for internal-combustion engines. The operation and wear characteristics of the valve are improved by virtue of the fact that a stroke-limiting plate (21) is located between the armature (15) and the stop surface (16) thus defining the distance between them. Mounted on the stop-surface side of the plate (21) is a support plate (27) which is acted on by a spring (29). The support plate (27) has a curved surface (25) which is seated on a matching inner, curved surface (23) on the stroke-limiting plate (21). The matching inner, curved surface (23) extends outwards into an outer, annular surface (22) which abuts the stop surface (16). The other, curved, side (19) of the stroke-limiting plate (21) rests on a matching surface (17) of the armature (15). The invention is intended in particular for motor vehicles.
