摘要： An electronically controlled or regulated fuel metering system for an internal combustion engine having one sensor each for the air flow in the intake tube and for the throttle valve position is proposed. In accordance with the signals of these sensors, influence can be exerted upon at least one of the operating states of lambda regulation, full load and fuel quantity limitation. The fundamental concept is that not only the air flow rate signal or only the signal relating to an opened throttle valve should be evaluated as a full-load signal but that the full-load state is presumed to exist when, with the throttle valve opened, the air throughput in the intake tube simultaneously exceeds a predetermined value as well. The same condition applies to full-load enrichment. The overall result is cleaner exhaust gas.

摘要： A fuel injection system is proposed for internal combustion engines having a plurality of injection valves for supplying fuel to the engine. Each injection valve is connected by a yieldable support bracket with a rigid fuel distributor line. The bracket is mounted pivotally with an annular coller secured to the injection valve. The fuel distributor line is arranged to engage rib-like carrier members connected with the internal combustion engine and is held against the carrier member by yielding clamp elements. After the valves are engaged in the sockets of the fuel distributor line and the bore of the cylinder head, then the support brackets are swung upwardly to tension the seal elements that are disposed in proximity to the opposite ends of the valve. As a result, not only a more secure connection between the fuel distributor line and the injection valves is obtained, but also rapid assembly or disassembly of the fuel injection system.

摘要： The invention is directed to a method and an apparatus for controlling the overrun mode of operation of an internal combustion engine, wherein instantaneous values of the relevant negative speed change of the internal combustion engine are sensed and evaluated to control the overrun mode. In this arrangement, a higher resume speed which is selected on commencement of the overrun mode and reduced to a lower speed limit after a predetermined time function, can be shifted additionally in dependence on the negative speed change. Further, to keep an internal combustion engine from stalling, the actual value of the negative speed change can be compared with a predetermined desired value; if it exceeds that value, the decision for a resume of fuel delivery can be made without delay.

摘要： In order to prevent undesirable abrupt changes in engine torque when the fuel supply to the engine is shut off at the onset of engine braking, the invention provides the gradual decrease of the amount of fuel supplied to the engine beginning with the onset of engine braking and continuing until fuel has decreased to approximately 80 percent of the normal amount at which time the fuel is shut off entirely. When engine braking stops or when the operator indicates a demand for acceleration, the fuel supply is initiated at the level of approximately 80 percent of normal and is increased thereafter up to the normal amount according to a second selectable function of time.

摘要： The cyclic control pulses for actuating the fuel injection valves of an internal combustion engine are extended during engine starting at low temperatures. The degree of pulse extension, i.e. of fuel enrichment, is made dependent on engine temperature and decreases as a function of cranking time. In addition, a repeated starting attempt will be accompanied by reduced pulse extension to prevent excessive enrichment of the mixture. The pulse extension may also be retained for a period of time after engine cranking to insure smooth running.

摘要： There is described a method and an apparatus for use with the fuel preparation system of an internal combustion engine, for example, a fuel injection system which operates injection valves with electrical control pulses. When the gas pedal of a vehicle is actuated abruptly, the air flow measuring device of such systems is subject to oscillations around its equilibrium point, and the initial one of these swings is used to cause enrichment of the fuel-air mixture. The return swing generates an undesired lean signal which is suppressed by a "damping circuit". In addition, there is provided mixture enriching during steady applications of the gas pedal by means of a time-decaying enrichment signal generated by a slow acting circuit which operates in superposition to the action of the damping circuit. Both circuits may be suppressed by a blocking circuit during certain engine conditions, for example, during engine starting and engine overrunning as well as on the basis of temperature.

摘要： A method of and a device for regulating air-fuel ratio of an internal combustion engine includes an oxygen or lambda probe and a signal processing unit connected to the lambda probe. The change-overs of the lambda signal at the output of the lambda probe are compared with a succession of adjustable first time intervals t.sub.1 and, when no change-over is detected during the first time interval, the output signal from the signal processing unit which controls the air-fuel ratio is abruptly changed in a jump. To avoid overshoot of the output control signal, there is provided a resetting unit by means of which the jump of the control signal is reversed when the change-over of the lambda signal occurs in an additional monitoring time interval t.sub.2 following the first monitoring time interval t.sub.1.
