摘要： A fuel-supply system for an internal combustion engine, particularly of a motor vehicle. The fuel-supply system is provided with a pump for delivering fuel into a storage chamber and for producing a pressure in the storage chamber. In addition, provision is made for a pressure sensor for measuring an actual value of the pressure in the storage chamber, as well as a pressure-control valve for influencing the pressure in the storage chamber. A control unit is provided with means by which the pressure in the storage chamber is controllable to a setpoint value. In addition, the control unit is provided with means by which the closed-loop control of the pressure in the storage chamber is able to be superseded by an open-loop control.

A spray-discharge nozzle with at least one spray-discharge opening is hydraulically connected via a fuel pressure line to the pump piston. The spray-discharge nozzle opens when the fuel pressure produced by the pump piston in the fuel pressure line exceeds a predetermined threshold. In the fuel pressure line, at least one non-return valve is arranged so that it opens in the direction towards the spray-discharge nozzle and closes in the opposite direction.

摘要： A fuel supply systems with two series-connected pumps and with fuel injection valves that inject fuel directly into a combustion chamber of an engine in which a starting process takes less time because of the small feed quantity of the second fuel pump. The system includes a valve device which assures that during the starting process the first fuel pump furnishes the fuel to the fuel valves at elevated feed pressure. In many cases, this elevated feed pressure suffices to start the engine in the quickest possible time. The apparatus and the method are intended for an internal combustion engine of a vehicle.

摘要： A device is proposed for measuring the composition of fluids, in particular of constituents of exhaust gases from internal combustion engines, in which a light ray (32, 31) is used to irradiate the exhaust gas to be measured over the length of a measuring section (29) and is weakened or changed more or less, depending on the content of constituents. The light signal being received is advantageously registered by a measured length light receiver (18) which is shielded light-tight against the light emitting light source (14) and is evaluated in relation to the original light emission, in an evaluation circuit (26). In this simple way, accurate information is obtained of the exhaust gas clouding and of the loading of a fluid or gas with constituents which are optically active.

摘要： An apparatus for measuring particulate matter in a flue gas or exhaust gas of a combustion process comprising means for transmitting a beam of light between an optical transmitter and an optical receiver. The light passes through two diametrically opposed light slits closed by transparent bodies in the wall of the tail pipe and crosses through a flow of exhaust gas carried in the tail pipe. The attenuation of intensity of the light beam is a measure of the particulate matter. When the measuring apparatus is used to measure a soot concentration in an exhaust gas of internal combustion engines of a vehicle, it is mounted directly on the tail pipe, and the transparent bodies are heated in the vicinity of the faces acted upon by the exhaust gas flow to a temperature above the soot burn-off temperature. As a result, adulteration of the measured value by soot deposits in the measurement path to the transparent bodies is prevented, and continuous operation of the measuring apparatus is assured.

摘要： A device for measuring particle emissions of an internal combustion engine, in particular the soot concentration in the exhaust gas, has a signal transmission route, located between a transmitter and a receiver, which traverses a flow of exhaust gas carried in an exhaust gas tube of the engine. To avoid soiling of the active elements of the transmitter and receiver that would cause inaccuracies in measurement, the signal transmission route is embodied as a beam of light, which passes through two diametrically opposed openings in the wall of the exhaust tube. The light-admitting openings are each closed with a respective transparent disk. The disks are heatable and are heated to a temperature above the burnoff temperature of the particles. Appropriate light emitting and receiving elements are used in combination with appropriate heating and evaluation circuits which indicate the soot concentration and which control fuel input to change the soot concentration.
