摘要： A tank-venting arrangement includes: a tank having a tank closure; an electrically drivable check valve; an adsorption filter; connecting lines for interconnecting the above components; a difference pressure sensor which measures the pressure difference between the pressure in the tank and the ambient pressure and supplies a pressure difference signal; a comparator which, at least for a running engine, compares the pressure difference signal to upper and lower threshold values and supplies an opening signal to the check valve to open the latter when the pressure difference signal is greater than the upper threshold value and a closure signal for closing the check valve when the pressure difference signal drops below the lower threshold value; and, a detector unit which supplies an opening signal to the check valve for opening the check valve when the sensor determines a possible opening of the tank and a closure signal for closing the check valve when the sensor determines a possible closure of the tank. With the aid of the check valve and the difference pressure sensor which measures the pressure difference between the pressure in the tank and the ambient pressure, the tank-venting arrangement can be so operated that at least for a running engine, a desired maximum overpressure in the tank can be obtained relative to the ambient pressure independently of the extent of the underpressure in that part of the arrangement forward of the check valve.
摘要翻译：排气装置包括：具有罐盖的罐; 电驱动止回阀; 吸附过滤器; 用于连接上述部件的连接线; 差压传感器，其测量罐中的压力与环境压力之间的压力差，并提供压力差信号; 比较器，其至少对于运行的发动机，将压力差信号与上限和下限阈值进行比较，并且当压力差信号大于上限阈值时，向止回阀提供打开信号以打开后者，当压力差信号下降到低于阈值时关闭止回阀的信号; 以及检测器单元，当传感器确定罐的可能打开时，检测器单元向打开止回阀的打开信号提供打开信号，以及当传感器确定罐可能关闭时关闭止回阀的关闭信号。借助于止回阀和差压传感器，该差压传感器测量罐中的压力与环境压力之间的压力差，罐排气装置可以如此操作，使得至少对于运行的发动机来说，期望的最大超压在可以独立于止回阀向前的布置部分的负压程度，相对于环境压力获得罐。

摘要： The invention is directed to a method for checking the tightness of a tank-venting system when a pregiven test condition is satisfied. The method includes the steps of: (a) building up a difference pressure in the tank-venting system irrespective of whether the pregiven test condition is satisfied; (b) determining the presence of the test condition and then closing the tank-venting system; (c) determining the value of the decay gradient of the difference pressure when the pregiven test condition is satisfied thereby losing no time in starting the check of the tightness; and, (d) drawing a conclusion as to the tightness of the tank-venting system when the value of the decay gradient is less in magnitude than a threshold decay gradient. In this way, as soon as the test condition is satisfied, a determination of the value of the decay gradient of the difference pressure already built up can be started. An apparatus for carrying out the method is also disclosed.

摘要： A method for checking the operability of a tank-venting system for a motor vehicle having an internal combustion engine with a lambda controller, which system has an adsorption filter with a connecting line to a tank and a connecting line to the intake pipe of the engine which is provided with a tank-venting valve. The method is characterized in that a lean correction check is performed as soon as an operating condition with low air throughput through the engine is present. If the check determines a lean correction (.DELTA.FR) of the lambda controller which is less than a pregiven lean correction threshold value (.DELTA.FR.sub.-- SW), there is a pressure change check provided with respect to the pressure in the tank as soon as an operating condition is present with a high air throughput through the tank-venting valve. The tank-venting system is deemed to be operative if a pressure change effect of pregiven quality (.DELTA.Dp>.DELTA.Dp.sub.-- SW) is determined. This method has the advantage that the pressure change check, which interferes with the tank-venting operation, is only performed when the first performed lean correction check indicates that there is only a small amount of fuel to be regenerated. In this case, arbitrary closing operations of the tank-venting valve for the pressure check do not disturb the tank-venting operation in a significant manner.

摘要： In a system and a method for determining the speed gradient dn/dt of a shaft of an internal combustion engine, the speed gradient dn/dt is determined as a function of the third power of the speed and the difference between two segment times in the control device. The speed gradient is only determined in phases which are not time-critical, while segment times are read in or stored only in time-critical phases so that the data required for controlling and regulating the internal combustion engine can be calculated in these time-critical phases independently from the determination of the speed gradient.

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： A method for checking the operability of a tank-venting system for a motor vehicle having an internal combustion engine (10), the system including an adsorption filter (14) having a venting opening (17) at its venting end and having a connecting line (16) to a tank (15) as well as a tank-venting valve (13) which is connected into a connecting line (12) between the intake pipe (11) of the engine and the intake end of the adsorption filter, characterized in that:a difference pressure (Dp) is measured which is a measure for the pressure difference between the venting end and the intake end of the adsorption filter; and,a conclusion is drawn as to inadequate throughput capacity of the adsorption filter when the measured difference pressure exceeds a threshold value (Dp.sub.-- SW).With this method, as with similar methods provided in the disclosure, it is possible for the first time to check the throughput capacity of an adsorption filter in a tank-venting system. A tank-venting system can be overall checked better as to operability than previously when this method is used in addition to methods previously known which, for example, check the tightness of the system or the operability of the tank-venting valve.

摘要： An adsorption filter is linked to the atmosphere by a breather line to prevent condensates from settling in the shut-off valve, as they flow through the breather, so that this valve becomes unable to function. The breather has a vertical arrangement of the shut-off valve with a magnetic circuit arranged above the valve operative parts to ensure that any condensate which forms can flow off, without impairing the function of the shut-off valve (51, 51'). The breather is particularly suitable for internal combustion engines in motor vehicles.
