摘要： To prevent contamination of confining surfaces of vessels through which a light beam is passed, the attenuation of which is a measure of the optical transparency of exhaust gases from Diesel engines, transparent disks, such as glass disks, are rotated adjacent the chamber and heated, for example by gas jets or an infrared source to such a temperature that the disk temperature is raised to a level sufficient to burn off any residual deposits left by the gases on the disks, so that the transparency of the disk will not be impaired and adulterate the measuring results.

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.

摘要： The device for testing an ignition system of a combustion engine comprises an adjustable load connected in the primary winding of the ignition coil by means of which the stored energy is so long reduced until due to the deficient energy the first ignition slip of the fuel-air-mixture occurs. This reduced energy is compared with the nominal or normal energy required for proper operation of the ignition system and the difference between the two values determines a measure for ignition energy reserve and consequently a measure for the condition of the whole ignition system. The energy reserve is measured selectively always for a part of the ignition system, that means for a cylinder of the engine. For this purpose a selective switch is employed using a scaler fed by pulses derived from the contact breaker and synchronized by a pulse from the part of the cylinder under test produce an output pulse which connects the loading member to the primary winding of the ignition coil.

摘要： To provide for accurate testing of the performance of automotive vehicles on test stands in which the wheels of the vehicle are in engagement with inertia rollers, the inertia rollers being accelerated through the vehicle wheels by the vehicle engine, and the torque measured, and then decelerated by disconnecting of engine driving power and coasting torque measured, operating parameters related to speed and rate of change of speed are sensed and a speed signal is provided, tractive effort is sensed and a traction signal provided, and the signals are combined to provide an output representative of engine performance, the combined signals being further modified by the output of a correction stage which introduces correction signals such as pressure, ambient temperature, presence or absence of automatic transmission, or the like; the apparatus further comprises selectable switches, for example a speed selector switch, so that measurements can be taken with respect to predetermined design speeds to test performance of the vehicle, or an engine, with respect to such a predetermined speed.
