Title: Device for the control of fuel metering into an internal combustion engine
Inventor: PIWONKA FRIDOLIN DR ING
IPC: F02D45/00
Filed: 1984-03-21
Abstract: A device for controlling the metering of fuel into an internal combustion engine is proposed, in which the inputs of the driver for the influencing of certain controls are fed in not by the selection of a certain operating element of the corresponding control but by certain, predeterminable operating states of the vehicle. In the example embodiment described, two operating elements for the inputs of the driver are connected in parallel or in series and connected to the electronic control unit for influencing of the fuel metering into the internal combustion engine. The inputs of the driver on one of the two operating elements are then fed by the control unit to the corresponding controls according to the speed of travel of the vehicle. It is thereby also possible to actuate the intermediate speed control and the speed-of-travel control from just one operating element. <IMAGE>

Title: Method for reducing knocking in an internal combustion engine
Inventor: AKASU MASAHIRA
IPC: F02P5/152
Filed: 1984-04-19
Abstract: A method for reducing knocking in an internal combustion engine permits an improved response to changes of the operating conditions of the engine and permits precise knocking control under all combinations of operating conditions. The knocking level, the load state and the engine speed are determined. At addresses of a memory device, which are defined by the load and the engine speed, values are stored which are calculated in accordance with the detected knocking levels. Some of these values are read out according to addresses in line with a combination of a load condition and an engine speed which occurs. At least one control parameter such as, for example, the ignition timing, is corrected on the basis of the values read out from the memory and on the basis of the detected knocking level. The values stored in the memory are altered in both directions at predetermined intervals.

Title: Method for the injection of H2O mist into the engine cylinder
Inventor: KREYER EDMUND
IPC: F02B3/06
Filed: 1985-03-14
Abstract: In internal combustion engines of known design the pv diagram has a pointed shape, since combustion occurs abruptly. In order to prevent this the cylinder head of the engine is equipped with a freely movable opposed piston, which evens out the pressure peak occurring at ignition and as expansion progresses performs work.   For this purpose it is necessary to fill the opposed piston cavity with a gas, the pressure of which is lower than the maximum pressure in the working cylinder. A compressible liquid, for example oil or a combination of both media, also fulfils this function.
