摘要： A control system for the fuel injection mechanism of an internal combustion engine, especially a Diesel engine. In order to adapt the fuel admitted to the engine to exact requirements, a correction is made on the basis of air mass flow rate and fuel temperature. The air mass flow rate is deduced from signals generated by an air temperature sensor and an air pressure sensor while the fuel temperature is taken by a fuel temperature sensor. The two temperature signals are applied to a bridge circuit which feeds a differential amplifier whose output is mixed with the pressure signal. The composite mixed signal is applied to a servo-mechanism to limit the excursion of the fuel control rack of the fuel injection pump. Status indicators generate feedback signals for comparison with set-point signals to provide closed-loop control.

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： A fuel injection system for an internal combustion engine is controlled by a follower control loop. The fuel quantity is arbitrarily set by the gas pedal and a first potentiometric transducer generates an electrical command signal. The air flow through the induction tube constitutes the controlled variable whose magnitude is transformed into an electrical signal by a second potentiometer coupled to an air flow rate meter. The two signals are compared at the input of a control amplifier which drives a servomotor. The servomotor adjusts the opening of the air throttle valve of the engine, thereby changing the air flow through the induction tube until the air flow rate meter signals that the air quantity is proportional to the metered out fuel quantity.

摘要： A compartment in a housing has a wall serving as a pressure diaphragm in communication with the contained fluid to be measured. A measuring element with a spherical cap is arranged in the compartment for the uniform transmission of pressure to electrically responsive pressure sensitive means on the measuring element. The measuring element contacts the pressure diaphragm at virtually only a single point. The diameter of the measuring element and, accordingly, of the compartment which includes the measuring element, can be considerably reduced, so that the mechanical strength of the pressure sensor is increased.

摘要： To permit ready matching of a Diesel engine operating circuit to a glow plug system, an interface-and-control unit (1) is provided which includes a microprocessor (MP) which decodes data words received from an engine control unit (MS). The data words are in the form of serially transmitted bits which define, by time duration of the bits. respectively logic "0" and logic "1" values to provide, inherently, simultaneously data information and synchronizing information. For example, the logic "0" bits may be 1/8 of a predetermined clock period (T) whereas the logic "1" bits may be 1/2 of the clock period (T). The microprocessor, thus, can be easily matched to engines of different types and can carry out, on its own, diagnostic routines and indicator functions under command of respective bits being transmitted thereto. Preferably, glow plug current is provided in pulsed form, the duty cycle of which is controlled by four data bits (D0-D4) transmitted to the microprocessor (MP).

摘要： In a safety and emergency driving control method and an associated arrangement for an internal combustion engine with self-ignition used to power a motor vehicle, various operating parameters of the engine are continuously monitored and respective signals indicative of gas pedal position, engine operating speed, brake actuation, and actual control rod displacement are generated and evaluated to determine simultaneous occurrence of a modified idling operation condition and of a predetermined minimum value of the actual control rod displacement signal. In response to such a simultaneous occurrence the engine control is switched over to another regulation branch which controls the control rod displacement in accordance with a minimum value characteristic line of the control rod displacement. Further peripheral devices are included for providing starting hysteresis and excess speed protection, and for supervising the operation of the control rod displacement sensor. A supervisory device associated with a main computer of the arrangement may also be used to achieve the switch-over independently ofexternal signals.

摘要： Disclosed is a system for recirculating exhaust gas in an internal combustion engine having an exhaust gas recirculating conduit which is provided with a valve controlled by two solenoid windings. The system includes a control device including a PID regulator having limitations and cooperating with a three-point switching circuit which exhibits a hysteresis and includes a feedback. The energizing signals for the two solenoid windings are limited between a minimum and a maximum value, whereby the minimum value is defined by the operational sensitivity of the exhaust gas recirculating valve.

摘要： A control device is proposed for regulating the exhaust gas recycling rate in an internal combustion engine with self-ignition in which combustion pressure signals are adjusted directly or indirectly to nominal values dependent on operating characteristics of the engine. In one particular embodiment the combustion pressure signal is differentiated and the frequency of certain occurring amplitude values is adjusted to a nominal value. Owing to the integration of specific combustion processes into the regulation, the device is capable of operating with relatively high precision. It is particularly well suited to compensate for drift phenomena.

摘要： An rpm-to-voltage converter for use in vehicles, in which the converter evaluates the time period between two sequential rpm pulses. This is accomplished by means of a capacitor loading and unloading in an approximately hyperbolic course, so that the inversely proportional relationship between the frequency and the period duration is evaluated for the frequency-to-voltage conversion. The primary characteristics of the converter are a capacitor which can be periodically loaded and unloaded, the exponential voltage course of which during the loading phase is followed by means of an emitter follower, and at the end of the loading procedure the voltage value proportional to the rpm is stored in a memory device.
