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 fuel injection system for an internal combustion engine whose air induction tube contains an air flow rate measuring member with non-linear operating characteristics, coupled to a potentiometric transducer which produces the electric command variable for a follower control loop. A control amplifier drives a servomotor which sets the metering slide of a fuel metering valve assembly. The servomotor shaft is coupled to a second potentiometric transducer whose output is compared with the command variable in a bridge circuit connected to the input of the control amplifier. The mechanical link between the servomotor and the fuel metering slide has a non-linearity similar to that of the air flow rate measuring member.

摘要： A method for measuring the air quantity supplied to an internal combustion engine by means of a measurement sensor disposed in a bridge circuit having a temperature-dependent resistor (for example, a hot wire or hot film) in the air intake manifold and having a temperature control apparatus, the temperature of the measurement sensor being controlled in an open or closed loop independently of the temperature of the medium to be measured, the properties of the medium to be measured which cause the measurement effect in the hot wire or hot film being dependent on the temperature. With an identical flow quantity but different temperatures in the medium, a correct measurement indication is obtained by making the excess temperature of the hot wire dependent on the temperature of the medium to be measured. The apparatus for open-loop or closed-loop control of this excess temperature contains, in the parallel arm to the quantity measurement device of the bridge circuit, two resistors disposed in sequence, one of which is also disposed in the air intake manifold in order to detect the air temperature, and the total temperature coefficient is set, by means of the selection of the individual temperature coefficients of the two resistors as well as their resistance values, in such a manner that the actual measurement sensor has a controlled excess temperature.

摘要： The airflow rate through the induction tube of an internal combustion engine is measured by a first transducer which delivers a set point signal to a control amplifier. The amplifier also receives a feedback signal from a second transducer which monitors the position of a servo-motor controlling the quantity of fuel metered out to the engine. The feedback loop maintains a desired fuel-air ratio and includes provision for calibration and adjustment.

摘要： A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.

摘要： A method and an apparatus are proposed for determining and controlling an exhaust gas recirculation rate in internal combustion engines (Diesel engines), wherein an adjusting member in the exhaust gas recirculation line is adjusted by a regulator in order to attain precise regulation of the exhaust gas quantity recirculated to the aspirated air zone. The regulator is supplied with the exhaust gas temperature (T4) measured at a given time as the load signal for the engine. The comparison value of the regulator is then either an actual value of the exhaust gas recirculation rate, ascertained by means of effective temperature measurements in the intake zone of the engine, or a set-point differential temperature which is produced by means of measuring the aspirated air quantity at a given time and the rpm.

摘要： A regulator shaft, rotary centrifugal weights, and a governor member which is slidable on the regulator shaft, are arranged in a pressurized, fuel-filled inner chamber of a fuel injection apparatus. The centrifugal weights engage regulator springs via the governor member and a control sleeve. The governor member is closed adjacent the free end of the regulator shaft except for a throttle opening for communication with the inner chamber. The governor member is provided with a work chamber, one extremity of which is limited by the regulator shaft. A conduit leading to a fuel tank communicates with the work chamber. A magnetic valve connected to an electronic control device for control of the fuel flow is provided in the conduit. Opening the magnetic valve causes a pressure drop in the work chamber which in turn causes the governor member to press against the centrifugal weights, thus enhancing the fuel injection quantity so as to reduce deviations from those desired and pre-set.
