摘要： A safety device is proposed for an internal combustion engine which is operated with supercharging in combination with both a fuel metering system and a control unit for the instant of ignition. The safety device is characterized in that it controls the fuel metering in accordane with the volumetric efficiency of the engine. In the case of an excessively high volumetric efficiency, a defect of the charger or of the charge-pressure regulator is presumed. In order to protect the engine from mechanical and thermal overload, the fuel metering in this case is either reduced or shut off completely. The subsequent reinitiation of the fuel metering is suitably effected in combination with a late instant of ignition or a late injection onset in order to prevent a jump in torque.

摘要： An electronic arrangement for controlling gas exchange valves of an internal combustion engine with variable valve control is presented. The valve control makes possible to completely hold closed at least the inlet valves and the electronic arrangement is equipped with means for detecting the air quantity, which is inducted by the engine, and with means for detecting the valve stroke. The electronic control arrangement changes the opening function in overrun operation starting from the fully closed inlet valves so that an opening of the inlet valves takes place and the arrangement detects the index of the valve opening at which a reaction of the air quantity detection takes place and uses this index as a reference point for determining the actual opening cross section.

摘要： The invention is directed to a method for detecting a fill level of a tank system utilizing a pressure source, a bridge divider arrangement and a pressure measuring device. The pressure source is adapted to generate a change of pressure in the tank system. The pressure divider arrangement has a reference measuring unit which can be charged with pressure by the pressure source. The reference measuring unit further includes at least one flow resistor of a predetermined size in at least one reference flow branch. For measuring the tightness, the pressure measuring device simultaneously detects the difference of the pressure in the tank system and of the pressure in the reference measuring unit. In the method, the time-dependent trace of the difference pressure during at least one of a pressure build-up operation and a pressure decay operation is continuously detected. A conclusion is then drawn as to the fill level from the time-dependent trace.

摘要： The invention is directed to a method for detecting and documenting exhaust-gas relevant malfunctions of a vehicle having an internal combustion engine and a fuel tank utilizing on-board diagnosis. In the method, malfunctions are detected utilizing a sensor device and the malfunctions are evaluated in a circuit unit with the malfunctions including those malfunctions which are based on an empty tank. The fault announcements of the malfunctions are stored in a memory in dependence upon a pregiven number of drive cycles. A fill-level value indicative of the level of fuel in the fuel tank is determined and stored in the memory. Fault announcements of the malfunctions are outputted and stored in the memory in dependence upon the fill-level value thereby eliminating fault announcements of the malfunctions based on an empty tank.

摘要： In the venting apparatus (1) according to the invention, a first, small-volume adsorption filter (4) is accommodated in the front area of a motor vehicle, in the region of the internal combustion engine and a second, large-volume adsorption filter (5) is accommodated in the region of a fuel tank (2). The fuel vapors evolved in the fuel tank (2) are introduced into the second adsorption filter (5) via a tank conduit (10) and into the first adsorption filter (4) via a connecting conduit (11) and, after flowing through the latter, into an intake pipe (20) of the internal combustion engine. The large-volume embodiment of the second adsorption filter (5) ensures that the fuel vapors evolved are reliably retained, and heating of the first adsorption filter (4) ensures that abrupt changes in the fuel/air mixture fed to the internal combustion engine are avoided.
