摘要： The quality of the external air is determined by means of a pollutant sensor. The quality of the internal air is determined by calculation taking account of the air quantities introduced from outside into the internal space. A decision between air supply operation and air recirculation operation is then made on the basis of a comparison of the air qualities inside and outside. The pollutant sensor is preferably located in a casing whose internal space is accessible to gases through an opening which is preferably sealed by a gas-permeable membrane.

摘要： A process and equipment for removing toxic and malodorous gases from the fresh air for vehicle cabins by catalytic oxidation, the process being based on passing the fresh air over a heating-system heat exchanger, the heat-emitting surfaces of which form the support for an oxidation catalyst. The heat exchanger used is the heating-system heat exchanger which is present in virtually all motor vehicles. In contrast to known solutions for purifying the fresh air, for example by means of activated carbon, the process is maintenance-free and does not require any additional constructional volume.

摘要： A method for testing and adjusting catalytic exhaust gas emission control systems of internal combustion engines, in which the fuel-air-ratio is regulated by means of a .lambda.-probe (control-probe) arranged in the exhaust gas stream upstream of the catalyst, whereby the exhaust gas stream is measured downstream of the catalyst by means of a further .lambda.-probe (test-probe). The voltage average value and amplitude magnitude of the signal produced by the test-probe are determined and serve for adjusting the operating point of the control system and for the recognition of the catalyst efficiency.

摘要： A measuring device that is moved corresponding to the amount of medium flowing through a housing is provided for measuring the flow rate of a gaseous or liquid medium through the housing. The displacement of the measuring device represents a measurement of the amount of medium flowing through the housing and during the displacement of which, a movable part of a control valve is adjusted for metering a control medium volume that is proportional to the flow of medium in the housing. The measuring means is pivotably mounted at an upstream end to the housing and, at a downstream end, rests against the wall of the housing in its closed position. In order to provide an arrangement that is simple to manufacture and is not susceptible to momentary disturbances and which records the measured values exactly, the measuring means comprises a concavely shaped leaf spring which interacts with the flow of medium.

摘要： A fuel-injected internal combustion engine wherein fuel is injected in dependence upon a quantity or volume of air supplied to the engine. A throttle valve controls the airflow rate with an O.sub.2 probe, arranged in an exhaust manifold, controlling a timing valve through a control device for enabling a timed relief of injection pressure of the fuel. An ignition starter switch is connected to the control device in such a manner that the timing valve is fully open during an operation of the ignition starter switch so as to enable a starting boost. An adjustable timing member is coupled to an operating switch provided in the control device, which operating switch closes automatically after a termination of the starting process. The timing member maintains the timing valve in a fully open position during a specific time span so as to provide for an after-start boost. An additional timing member is adapted to maintain the timing valve in a fully open position during a short time span so as to enable an acceleration enrichment. The control device renders the start boost, after-start boost, and acceleration enrichment ineffective upon the probe reaching its normal operating temperature.

摘要： An exhaust gas filter for Diesel engines that consists of a filter block made of a porous ceramic material, and a plurality of ducts extending through said filter block that extend in the flow direction of the exhaust gases. The ducts in each case are alternately closed at their upstream or their downstream end, whereby the exhaust gases are forced to penetrate a filtering separating wall between two ducts. The closing means at the downstream end, are arranged so that they are staggered with respect to one another in the flow direction; in particular they are staggered by about 5 to 150 mm. The staggered arrangement of the closing means reduces the danger of a thermal damage to the filter block during the burning-off of the deposited soot.

摘要： A fuel injection system for a mixture-compressing spark ignition internal-combustion engine has a fuel-metering device having a housing with a control cylinder arranged therein, a control piston having at least two control edges being rotatably and longitudinally slidably arranged in said control cylinder. One front surface of said control piston is acted upon by fuel and its other front surface interacts with a pressure spring. Between the control edges, the control piston is equipped with a control space area. The housing has an inflow opening for a fuel inflow pipe, an outflow opening for a fuel return flow pipe in which a pressure regulating valve is arranged, and an outflow opening assigned to a fuel injection nozzle. The outflow opening connected with a control opening in the control cylinder interacts with the control edges. The control space area has at least one recess at the control piston having a circular-arc-shaped area segment forming the control edges in order to provide a fuel injection system having a fuel-metering device of the initially mentioned type which is simple to manufacture and easy to assemble, exhibits high operational reliability and ensures an exact metering of fuel. The axis of said area segment extends transversely to the control piston axis and starts from the circumferential area of the control piston in a concavely curved manner extends into the control piston. The control piston has an axial flow-through bore equipped with a throttle downstream from the recess. The fuel passes through said flow-through bore from the inflow opening of the housing to the recess and to the outflow opening of the housing.
