摘要： A method is proposed for determining the rough engine run of an internal combustion engine (10), wherein a signal processing arrangement (13-19, 30, 50, 51) determines the engine rotation from a signal (Ub) appearing at a generator (11) driven by the internal combustion engine (10) or at a load (12) connected to the generator (11). The signal (Ub) is composed of signal components including long period durations (Tm) and signal components including short period durations (Tmn) which are evaluated separately as well as together in an evaluation unit (15). The signal component including the short period durations (Tmn) can be derived from commutation oscillations (40) which occur within signal Ub if the generator (11) is configured as an alternating current/three-phase current generator and is equipped with rectifiers and phase fan-in.

摘要： A device for measuring a particulate concentration in motor vehicle exhaust gases, has a measuring chamber, which is able to be filled up with a gas-particulate mixture that is to be measured, at least one light source and at least one light sensor. The light sensor detects light that has been scattered by particulates present in the gas-particulate mixture. An exhaust gas supply device is developed to supply exhaust gas, that is to be measured, to the measuring chamber. A null gas low in particulates is able to be supplied from a null gas source to the measuring chamber. A switching element, which is situated between the exhaust gas supply device and the measuring chamber, is suitable for admitting or forestalling the supply of exhaust gas into the measuring chamber on an optional basis.

摘要： The invention relates to an arrangement which permits operating characteristic variables such as the crankshaft rotational speed and the content of exhaust gas components to be determined in the workshop. The sensor is mounted so as to be stationary in the exhaust gas system or is only intermittently mounted in this system. According to one arrangement of the invention, the exhaust gas sensor includes a first device which receives the pressure of the exhaust gas of the engine. In this way, the crankshaft rotational speed can be arrived at. A second device is arranged in the exhaust gas sensor which has an output signal which is a measure for the content of an exhaust gas component. A further embodiment of the arrangement of the invention includes an exhaust gas sensor having a first device which is configured as a fault meter, temperature sensor or as a hot wire flow meter. Other devices can be utilized to detect further variables of the exhaust gas and evaluate the same.
