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 apparatus for the regeneration of a soot-particle filter is located in the exhaust-gas line of an air-compression, fuel-injected internal-combustion engine. The apparatus regenerates the filter using a process which burns off the soot particles in the filter. A device in the intake line is actuable as a function of the engine load and engine speed and controls the cross-section of the intake line. To prevent damage to the soot-particle filter body during a transition of the internal-combustion engine into the deceleration mode, immediately after the transition into the deceleration mode of the internal-combustion engine, the process and apparatus move the device for controlling the intake-line cross-section first out of its open position into a position to reduce the line cross-section to a minimum and thereafter continuously into its open position.

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 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 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.
