摘要： An injection system for an internal combustion engine, in particular an engine operating on liquid gas as fuel or fuel component, includes an injection unit for each cylinder for direct fuel injection into the combustion chamber, and a fuel supply system with at least one fuel tank and an oscillating pump element configured as a displacer for delivery of the fuel. The pump element is provided with an elastic sealing element fitted in a housing and which divides a pump chamber into two subchambers sealed tightly against each other, the first subchamber being supplied with fuel via a fuel feed line of the fuel supply system, and the second subchamber being supplied with a secondary medium. The dead volumes of the pump element may be reduced by configuring the pump chamber as an annular chamber at least partially surrounding a shaft moving axially in a cylinder, which shaft is mechanically linked with the sealing element.

摘要： To compensate for temperature effects on the measuring signal of a pressure sensor which includes a membrane part with at least indirect signal generation and is a supporting base, the membrane part being deformed by the pressure to be measured and cooperable with a pressure sensing element, the the membrane part is constructed to include at least one pair of concentric cylindrical surfaces positioned at a small radial distance from each other. The cylindrical surfaces are closed along their circumference, and one of the cylindrical surfaces increases its diameter when subjected to pressure and the diameter of the other decreases. Changes of the two diameters in the same direction take place in the instance of a temperature change.

摘要： A method and apparatus for controlling the volume stream of a sub-quantity which is continuously removed from a gas stream and which is supplied and mixed with a gaseous dilutant stream, the sub-quantity is conducted from the main stream through a back-up region where the control of the flow of sub-quantity without affecting its composition is effected by a counterflow in a back-up region which is controllably directed in opposition to the sub-quantity flow such as by an annular upstream directed gap surrounding the sub-quantity conduit or by openings which are directed in a direction against the sub-quantity flow or by a pipe directing a flow against the discharge end of the sub-quantity flow. The sub-quantity flow is mixed in a mixing tunnel with a dilution gas and a small quantity of this mixed gas is removed for testing.

摘要： A charge amplifier circuit for balancing drift between periodically occurring measured signals includes a drift-compensating device with a sample/hold unit which is triggered by a trigger device in accordance with the period of the measured signals. The trigger device is connected for supplying trigger pulses, so that the drift at an output of the charge amplifier, determined at the end of a compensation period, can be taken into account by the sample/hold unit to supply a compensating current to an input of the charge amplifier. The triggering of the sample/hold unit can be performed by external or internal triggering arrangements, so that simple measurements can be undertaken without a large outlay of equipment.

摘要： An engine brake in an internal combustion engine for use in motor vehicles, comprising an exhaust valve controlled by a cam via a follower lever, and a device for leaving the exhaust valve slightly open during the combustion stroke. According to the invention the support bearing of the follower lever is designed to be adjustable in the direction of the supporting force P between two extreme positions, i.e. one corresponding to normal operation and the other one to braking, such that on braking the exhaust valve is lifted by 0.3 to 3 mm, preferably 0.5 to 2 mm, during the phase in which the base circle of the cam is in contact with the follower lever.

摘要： For the identification of the resonance characteristics of a piezo-electric transducer, an input signal having a variably selectable frequency is divided into two sub-signals of the same frequency to be tuned to one another, one of said sub-signals being independent of and the other thereof being dependent upon the electro-mechanical properties of a piezo-electric tranducer under test. A difference output signal is generated from the two sub-signals, this difference output signal being measured relative to a reference output signal derived from the input signal. The tuning of the two sub-signals in the measurement is undertaken constantly to zero and with a rated value actual value differential control of that part of the difference output signal lying in phase or, alternatively, 180.degree. out of phase with the reference output signal. The remaining part of the difference output signal which is phase-shifted 90.degree. relative to the reference output signal, is used as a measure of the resonance characteristic of the transducer.

摘要： In a level measuring device for electrically non-conductive liquids comprising a sensor which is positioned in a vessel and is in contact with the liquid, and further comprising an evaluation circuit connected to this sensor both compensation of a changing dielectric constant and a high degree of accuracy and resolution are achieved by placing a driver electrode 5 in the lower part of the vessel 1 at a position essentually coaxial to the sensor electrode 3, 4, and by placing a compensating electrode 6 between the driver electrode 5 and the wall 8 of the vessel 1, such that further capacitors are formed between the two electrodes 5 and 6 themselves as well as between them and the sensor electrode 3, 4 and between them and the wall 8 of the vessel 1.

摘要： In an internal combustion engine with cylinders inline and an overhead camshaft for actuation of the intake and exhaust valves, the camshaft is driven from the crankshaft by means of a driving gear and an intermediate shaft, the driving gear being rigidly connected to an outer cheek of the crankshaft. With this arrangement the distance between the crankshaft bearings remains unchanged and a minimum overall length of the engine is achieved. At the same time a speed reduction gear may be located anywhere between the crankshaft and the camshaft.
