摘要： A self-optimizing control method for optimizing the fuel/air ratio under non-steady conditions in an internal combustion engine is described; in this method, a probe is provided both before and after the catalyst. Control quantities and the time during which the post catalyst probe shows an undesirable fuel/air ratio are stored for certain specified engine-operating conditions in the non-steady range. When the same engine operating condition is repeated, reference is made to the stored control quantities and time and the control quantity is varied in the direction of the correct fuel/air ratio. The time now obtained is compared with the stored time and, if the time has decreased, the new control quantity and the new time are stored. The control values are iteratively corrected by repeating these procedures, when the same engine operating condition reappears, until the time reaches a minimum.

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： 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 system is provided for measuring the amount of oxygen in exhaust gas emitted by an internal-combustion engine. The system includes an exhaust pipe for conducting engine exhaust gas and a probe for determining the oxygen content of engine exhaust gases. The exhaust pipe has a side wall formed to include an aperture for continuously discharging a portion of the engine exhaust gas flowing through the pipe. The system further includes a support housing for positioning the probe at a location outside of the exhaust pipe in proximity to the side wall aperture so that the probe is exposed to the engine exhaust gas portion discharged through the aperture and for collecting exhaust gas in a space surrounding the probe. The aperture is sized to permit exhaust gas collected in the support housing to be reintroduced into the exhaust pipe so that collected exhaust gas will be exchanged continuously with exhaust gas flowing through the exhaust pipe.

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.

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.
