摘要： For a speed governing system for an internal combustion engine with self-ignition, which includes an electromagnetic final control element for influencing the injection quantity and a control unit having a governor for controlling the final control element, provisions are proposed which give the governor a high dynamic amplification in the range of a drop in the engine rpm, a dynamic amplification that drops from a higher value to a lower value in the range of a sudden drop of engine speed, that is, an rpm undercutting, and a flattened governor characteristic in the vicinity of the ends of the control range. A governor of this kind reacts very flexibly to changes in rpm and in particular does not enter a saturated state, and it adjusts to a new control state without disruptive reacceleration phenomena. A governor of this kind is particularly well suited for motor vehicles having a Diesel engine with a relatively large number of cylinders.

摘要： An electronic control system for the fuel quantity of an internal combustion engine having self-ignition is proposed, in which above a predetermined load threshold the increase in fuel quantity is limited and a regulation of exhaust gas temperature is performed. The load threshold is preferably approximately 75% of the full-load value, and it may be dependent on operating characteristics, for instance on the rpm. Depending upon the engine type, it may be useful to regulate not the absolute exhaust gas temperature but rather the difference between the exhaust gas temperature and the temperature of the aspirated air.

摘要： To provide a high output signal, a strain bolt (12, 12a) is screwed (13, 13a) into a tapped bore extending through the housing wall (10), the bolt having a bore (14) extending therethrough, and a region or zone (18) of reduced outer diameter to form a comparatively thin-walled tubular or sleeve-like region which, upon application of fluid, typically liquid fuel pressure within the housing, tends to elongate the portion of the bolt of reduced wall thickness; a piezo-ceramic transducer assembly, preferably formed of two oppositely polarized disks (23, 24) is clamped between an integral head (FIG. 1: 19) or a separate clamping nut (FIG. 2: 31) and the outer wall of the housing, or an abutment surface formed by the upper surface of an intermediately positioned tightening nut (FIG. 2: 19a) so that, upon application of fluid pressure, and straining of the thin-walled portion (18) of the bolt, the bias pressure on the piezo-ceramic disks (23, 24) changes, thus providing an output signal available from a central terminal (25a).

摘要： A method and an apparatus are proposed for regulating and attaining an anti-overload means in turbochargers and in internal combustion engines equipped therewith, serving in cost-favorable embodiment both in Otto (gasoline) engines and in Diesel engines to limit the air throughput of the engine in accordance with the engine speed and to provide that neither the turbocharger, as a result of exceeding its limit rpm, nor the engine can be endangered if the engine exceeds the permissible compression and combustion pressure. In summary, the intent is to attain a favorable adjustment of the exhaust turbocharger over the entire rpm range of the internal combustion engine. To this end, the exhaust gas quantity delivered to the exhaust turbocharger is controlled in accordance with the throughput, that is, in accordance with the air quantity delivered to the engine, with the aid of a bypass line. The air quantity delivered by way of the compression area of the exhaust turbocharger of the engine is detected ahead of the exhaust turbocharger, either with the aid of a direct air flow rate meter, or by means of a throttle restrictor and the detection of the underpressure being created at that point. This application is a divisional application of application Ser. No. 40,795 filed on May 21, 1979, now abandoned.

摘要： A fuel injection system for an internal combustion engine includes electromagnetic injection valves controlled by a fuel control unit which receives signals from a camshaft actuated switch, a position-dependent throttle transducer and an oxygen sensor. When the oxygen sensor changes output levels, the transmission of this information is delayed, by the action of a switching transistor controlled by a monostable multivibrator, for a period of time equal to the internal time constant of the multivibrator.

摘要： The ratio of the inductance of a measuring coil to that of a reference coil is formed by an operational amplifier. Specifically, the measuring coil is connected between the output and the inverting input of the operational amplifier, the reference coil being connected to the inverting input. An AC voltage having substantially symmetrical half waves is applied to the reference coil. The AC voltage is a triangular voltage generated by two additional operational amplifiers. An emitter-follower connected to the output furnishing the triangular voltage decreases the load on the operational amplifiers and therefore allows the connection of a multiplicity of computing stages to the one source of triangular voltage. Additional operational amplifier stages, in conjunction with diodes, constitute a full wave rectifier and filter for the output of the operational amplifier furnishing the ratio signal.

摘要： An apparatus is proposed which serves to control the ratio of air to fuel quantity of the operational mixture to be introduced into the combustion chambers of an internal combustion engine. The actual fuel quantity supplied via an injection apparatus (2) and the actual air quantity supplied via the intake manifold of the engine are measured and processed in a control apparatus (21) into a correction adjusting variable. The apparatus further functions with exhaust recirculation, with the aspirated fresh air quantity being dosed and the remnant filling of the gaseous filling introduced into the combustion chambers of the engine is replaced by recirculated exhaust gas. For the purpose of dosing the fresh air, a symmetrical throttle valve (14) is disposed in the intake manifold, whose position is transferred by means of pneumatic servomotor (23) to a second throttle device (12, 32), by means of which finally the quantity of the recirculated exhaust gas is determined.

摘要： A method and apparatus for controlling a Diesel engine by limiting the amount of fuel to be admitted to the engine in dependence on engine speed and on the air mass flow rate. The invention provides a primary set of stored data interrelating these variables. The primary data set is used to generate a set-point value for the position of a movable stop member which limits the mechanical travel of the fuel control rack in the fuel injection pump; the control rack is also subject to the action of a mechanical speed governor. Additional corrections of the maximum amount of fuel are made on the basis of air temperature and fuel temperature. Still further refinements include taking into account exhaust gas temperature and engine starting conditions. The final corrected set-point signal is then compared with the output from a position indicator which is attached to the stop member. A servo-controlled element corrects the position of the stop member until the error indications are minimized in a closed loop, feedback control circuit.

摘要： Associated with the fuel controller of a supercharged diesel engine is a mechanism which limits the maximum fuel quantity in all operational states as defined by engine speed and air flow rate. This mechanism includes a three dimensional cam, displaced in rotation by a first transducer responsive to rpm or air flow rate and further displaced axially by a second transducer responsive to the other of these variables. A cam follower attached to the main fuel control rod of the controller makes contact with and follows the surface of the cam, thereby limiting the maximum fuel quantity admitted to the engine. Special provisions permit an enlarged starting fuel quantity and also permit corrections on the basis of further parameters, such as temperature. Several embodiments are presented.
