摘要： A method and apparatus for determining the injected fuel quantity in internal combustion engines having self-ignition are proposed. A performance graph is prepared which includes the injected fuel quantity per stroke in accordance with the injection duration, with the rpm as a parameter. In order to avoid a fictive 0 point, the injection duration is shortened by a predetermined period of time and multiplicatively linked with an rpm signal, while linear rpm correction curves having a dependency of the rpm voltage on the injection duration can be assumed. At the output of an integrator by means of a sample and hold circuit, an injection quantity signal is produced whenever the rpm signal (Un) is supplied to the integrator for the integration process and the duration of the integration is determined on the basis of the injection duration signal (SD).

摘要： A method and apparatus for improving the acceleration behavior of a self-igniting internal combustion engine driven with an exhaust turbocharger by displacing the onset of injection during the acceleration phase toward "early", and a combustion chamber pressure is attained, which at least in part compensates for reduction in engine power caused by sluggishness of the turbocharger and a resultant smaller cylinder charge. Further increase in power is attained by means of an increase in the fuel component made possible by the adjustment of injection onset without exceeding the smoke limit of combustion. Apparatus are furthermore proposed for performing the method according to the invention, in which with the aid of an acceleration signal obtained by hydraulic or electric elements an adjustment toward "early" is effected in a hydraulically functioning injection adjustment device.

摘要： An apparatus for damping bounce-induced oscillations in an internal combustion engine having a fuel metering control for supplying fuel to the engine in accordance with various operational signals, which includes an engine speed sensor for generating an rpm signal proportional to the engine rpm, a signal differentiation circuit for producing an rpm differential signal from the rpm signal, and a phase-shifting circuit, connected to receive the rpm differential signal, for supplying to the fuel metering control a bounce damping signal which is proportional to the rpm differential signal and which is phase-displaced with respect to the rpm differential signal so that the fuel metering control supplies fuel to the engine to countercontrol the bounce-induced oscillations of the engine. In a preferred embodiment, the phase-shifting circuit includes a controllable dead time element for varying the phase displacement in accordance with the bounce frequency so as to compensate for the total system transit time of the apparatus, to thus effect countercontrolling of the bounce oscillations which is correctly phased and correct in frequency.

摘要： There is described a method and apparatus for use in association with the fuel injection pumps of Diesel engines to time the moment of injection. The method and apparatus described relate to a closed-loop control system which engages a final control element in the fuel injection pump that changes the injection timing, i.e. the onset of fuel delivery and, hence, the onset of fuel injection. The controlled variable is the moment of fuel injection, detected by suitable means placed near the injection valves. A set-point value for this instant is derived on the basis of stored data which correlate the correct moment of injection as a function of engine speed with various optimum conditions, for example, low fuel consumption, low smoke generation, low noise, etc. The selection of the proper characteristic curve from the stored data set is made automatically or manually. The time of occurrence of the actual value pulse and the time of the set-point pulse are compared, for example, by converting the former to analog form, and the resulting control deviation is obtained as a preferably digital counter content which is used to engage the final control element to reduce the deviation.

摘要： A fuel supply apparatus is proposed which serves to control a mixture-compressing, externally ignited internal combustion engine. The fuel supply apparatus includes at least one fuel depositing point in the air intake manifold, within which an air flow rate meter and an arbitrarily actuatable throttle valve are disposed in series and the air flow rate meter is moved against a restoring force in accordance with the air quantity flowing therethrough. The air flow rate meter, which is embodied as a flat rotary element in the shape of a circular sector, more or less widely opens an aperture which defines the cross-sectional width of the air intake manifold and is rotatably fixed about a rigid shaft extending in the direction of air flow. The intake manifold pressure upstream of the air flow rate meter acts on one side of the air flow rate meter, and the intake manifold pressure downstream of the air flow rate meter acts on the other side of the air flow rate meter. In a plane downstream of the air flow rate meter which is parallel to the aperture, there is an arbitrarily actuatable lobed element, by means of which the flow-through cross-sectional area at the aperture can be varied in accordance with the operating characteristics of the internal combustion engine.

摘要： A fuel supply system for mixture-comprising, externally ignited internal combustion engines is proposed, which serves to apportion a fuel quantity corresponding to the induced air quantity. The fuel supply system includes an air flow rate meter disposed in the air intake line which actuates a fuel apportionment valve in accordance with the induced air quantity. The restoring force of the air flow rate meter is effected by a control element which is acted upon by pressure fluid, whereby the control element and the pressure control valve each have an air chamber separated from a fuel chamber by a yielding element and in each fuel chamber the same fuel pressure upstream of the fuel apportionment valve and in each air chamber the same pressure in the air intake line upstream of the air flow rate meter prevails as is also effective downstream of the fuel apportionment valve.

摘要： A fuel injection apparatus is proposed for mixture-compressing, externally ignited internal combustion engines which serves to apportion a quantity of fuel corresponding to the aspirated air quantity and to effect good preparation of the fuel-air mixture. The fuel injection apparatus comprises a fuel apportionment valve which is actuatable by means of an air flow rate meter arranged in the air induction tube of the internal combustion engine and an arbitrarily actuatable throttle valve arranged downstream of the air flow rate meter. The air flow rate meter has a circular control body, which is rotatably arranged on a bearing shaft with its outer circumference facing in the opposite direction to the air flow and, being transversely arranged with respect to the air induction tube, opens to a greater or lesser degree an aperture which defines the air induction tube cross-sectional area. The air flow rate meter is moved against a return force in accordance with the air quantity flowing therethrough.

摘要： A fuel metering control loop which includes an exhaust gas sensor and an integrating controller. In order to operate the system at an air number which may differ from the most stable operating point of the oxygen sensor, the output signal from the controller is deliberately changed so as to override the command signals from the oxygen sensor. In particular, the output signal undergoes a step-change toward a higher or lower value at the times of reversal of sensor potential. Thus, the average value of the air number which the controller effectively maintains is different from the nominal value which would be obtained with direct sensor control. In another embodiment, the ongoing integration process is continued for some time beyond the sensor signal reversal.

摘要： A continuous fuel injection system for metering out fuel to the induction tube of an internal combustion engine. An air flow metering assembly in the induction tube includes a baffle plate which is set with its plane perpendicular to the air flow vector and is mounted on a shaft which slides axially in bearings. As a result of the air flow, the baffle plate is displaced axially to varying extent and this displacement is opposed by a restoring force provided by pressurized fuel and subject to adjustment on the basis of engine variables. A vaned impeller wheel, mounted on the baffle shaft, causes rotation of the shaft in the bearings, thereby eliminating static friction and preventing hysteresis effects. The centrifugal forces generated by the rotation aid in distributing the fuel and in admixing it with the incoming air.
