摘要： The oil pressure applied to a hydraulic device for controlling within a limited angular range of a cam shaft and its drive gear is controlled by a magnetic valve (35) which is switched between its open and closed position under control of the same microcomputer which controls engine ignition and/or fuel injection with reference to a predetermined function of some of the same engine operation parameters, namely engine speed and engine load, which are used to control ignition and/or fuel injection. The control function can advantageously also take account of rate of change of engine load or engine speed. A transducer (43) for reporting back the sleeve (22) which controls the mechanical rotary shift in response to oil pressure can be used to provide an actual value signal to the computer for generation of an error signal for controlling the magnetic valve so as to provide a continuous control of the overlap of the open periods of the intake and exhaust valves of the engine. The control function for the operation of the magnetic valve provides for hysteresis to prevent excessive switching back and forth.

摘要： A sensor is provided, in particular a gas sensor for determining the concentration of a gas component in a measuring gas, which has a sensor element that projects from a housing by a measuring-gas-side end section exposed to the measuring gas, and a sheath tube having gas passageways, which is placed over the measuring-gas-side end section and affixed on the housing. To prevent condensation of water vapor contained in the measuring gas in the measuring space enclosed by the housing and the sheath tube, and thus the production of water droplets that reach the hot sensor element, sheath tube and/or sensor element are/is thermally decoupled from the housing. The thermal decoupling is produced using, for instance, a flange sleeve made of a material having poor thermal conductivity, which separates the sheath tube from the housing by a flange and, via a sleeve section, is inserted in the space between the housing and the measuring-gas-side end section of the sensor element.

摘要： The invention is directed to a method for detecting and documenting damage to a catalytic converter in a motor vehicle having a fuel tank and an internal combustion engine wherein combustion misfires can occur when the level of fuel in the tank drops below a critical level. The method includes: detecting the level of fuel in the tank utilizing a fill-level sensor device; utilizing a circuit arrangement to determine when the level in the tank reaches the critical level and switching on a warning lamp to indicate that the critical level has been reached; storing a value corresponding to the critical level and the operating state of the warning lamp in a memory as a first set of data; detecting misfires of the engine and storing information as to the misfires in the memory as a second set of data; and, logically combining the first and second sets of data when the misfires are present at the same time as the critical fill level so that a determination can be made in the context of a later read out of the logically coupled data as to whether the misfires are associated with a level of the fuel corresponding to the critical level.

摘要： An apparatus for checking a tank venting system for leaks that serves to vent a fuel tank of a motor vehicle whose engine has a intake tube. The apparatus has an absorption filter connected to a ventilation line, which can be closed by means of a shutoff valve, and pressure producing devices for the production of an overpressure in the fuel tank. The pressure producing devices are embodied as actuatable by means of the vacuum in the intake tube in order to be able to forego the separate electromechanical drive devices for the pressure producing devices which have been necessary in the prior art.

摘要： A method for checking the operability of a tank-venting system in a vehicle having an internal combustion engine, which tank-venting system has a tank with a tank-pressure sensor, an adsorption filter connected to the tank via a tank-connecting line, and a tank-venting valve which is connected to the adsorption filter via a valve line, in which system the adsorption filter has a venting line which can be closed with the aid of a shut-off valve, has the following steps:closing the shut-off valve;opening the tank-venting valve;determining the build-up gradient (p+) of the underpressure building up in the tank;closing the tank-venting valve;determining the decay gradient (p-) of the decaying underpressure in the tank;mathematically combining the build-up and decay gradients in a manner such that the influence of the fill level has as little effect as possible on the evaluation variable (Q) formed by means of the combination; and,comparing the value of the evaluation variable with a threshold value (Q.sub.-- SW) and evaluating the system as non-operative if the value of the evaluation variable and the threshold value fulfill a pregiven relationship.
