摘要： Small change in the period of a crank-angle signal which is generated at every crankshaft rotation of a predetermined angle is not faithfully reflected to a false crank-angle signal which is used by a fuel injection control device for detecting the engine's running speed. Thus, even when the actual running speed is varied, the running speed recognized by the fuel injection control device doesn't change faithfully to this variation. Therefore, the amount of fuel injected into the engine, which amount is calculated in accordance with the running speed, doesn't vibrate with the variation of the running speed, preventing the surge phenomenon from occurring.
摘要翻译：在预定角度的每个曲轴旋转期间产生的曲轴角信号的周期的小的变化不被忠实地反映到由用于检测发动机的运行速度的燃料喷射控制装置使用的假曲柄角信号。因此，即使当实际行驶速度变化时，由燃料喷射控制装置识别的行驶速度也不会忠实地改变该变化。因此，根据行驶速度计算出的喷射到发动机的燃料量不会随着行驶速度的变化而振动，从而防止发生喘振现象。

摘要： An internal combustion engine fuel mixture control system is provided for use with an engine having a fuel supply and an intake air supply connected to the engine wherein the fuel and air mix to provide a combustible fuel/air mixture for the combustion engine. A fuel flow sensor is connected to the fuel supply line for the engine while an air flow sensor is similarly connected to the air intake of the engine and the outputs from the sensors are fed to a proportionator which provides an output signal representative of the instant fuel/air ratio for the engine and this output is coupled to one input of a differential amplifier. The other input of the differential amplifier is connected to a fuel/air ratio reference so that the output from the differential amplifier is representative of the difference between the reference and the actual fuel/air ratio for the engine. The output fromm the differential amplifier is used to vary the fuel flow to the engine.

摘要： An electronic control unit for regulating the air/fuel ratio of an internal combustion engine is disclosed. The electronic control unit has an open loop calibration for regulating air/fuel ratio that is corrected with a closed loop signal developed by an integral controller. The integral controller bases the closed loop correction signal on a signal from an exhaust gas composition sensor located in the engine exhaust manifold. Various conditions of the system are sensed by a closed loop sensor condition detector to provide information on whether the sensor is up to operating temperature and is operative. If the exhaust gas sensor is functioning and the operating system parameters indicate the system operation should move to closed loop control, the loop is closed by the condition detector. Included in the condition detector circuit is a timer whose cycle is RPM dependent. The timer will time out if the sensor has not indicated an operational capability in one timing cycle or a set number of RPM counts and will generate a signal indicating a sensor failure. After closing the loop, the detector circuit will check for a sensor transition on a periodic basis related to the authority of the integral controller and provide a signal to open the closed loop if the transition does not occur. A rich burst generator is provided to perturbate the loop periodically to produce a rich transition of the sensor if it is operable. A latching failure indicator circuit is additionally included in the system to energize a visual indicator and alert an operator if the failure condition occurs.

摘要： An electronic control unit for regulating the air/fuel ratio of an internal combustion engine is disclosed. The electronic control unit has an open loop calibration for regulating the air/fuel ratio that is corrected with a closed loop correction signal developed by an integral controller. The open loop calibration is a speed-density based schedule which is combined with corrections for special conditions to account for the operating parameters of the engine at any instant. Included in these special condition corrections are provisions for increasing the air/fuel ratio upon a deceleration sufficient enough to cause a rich air/fuel ratio breakthrough because of the EGR valve lag time. A deceleration detector senses decelerations in excess of this predetermined amount by measuring the rate of change of the pressure in the intake manifold of the engine. A fixed percentage increase in air/fuel ratio is switched into the open loop calibration when the deceleration exceeds the amount required for breakthrough. The feature is additionally inhibited at low engine speeds and when the EGR valve is not operational.
摘要翻译：公开了一种用于调节内燃机的空燃比的电子控制单元。电子控制单元具有开环校准，用于调节由积分控制器开发的闭环校正信号校正的空燃比。开环校准是基于速度密度的调度，其与特殊条件的校正相结合，以在任何时刻考虑发动机的操作参数。在这些特殊状况修正中包括用于增加足够大的空气/燃料比以使由于EGR阀滞后时间引起的空气/燃料比浓度变大的规定。减速检测器通过测量发动机的进气歧管中的压力变化率来感测超过该预定量的减速。当减速度超过突破所需的量时，空燃比的固定百分比增加被切换到开环校准。在低发动机转速和EGR阀不工作时，该特征被另外禁止。

摘要： The fuel feed device includes a fuel injector controlled by an electromagnetic valve. A metering system has a rotary member adapted to send an energizing signal into the electromagnet during a fraction of each turn of the member. A signal generator is adapted to employ, on each turn of the rotary member, a release signal which lasts during a predetermined and constant fraction of a turn of the rotary member to produce the energizing signal whose duration varies in the same sense as that of the release signal and in the same sense as the degree of opening of an auxiliary throttle member in the intake pipe upstream of the main throttle. The auxiliary throttle opens automatically and progressively in proportion as the flow of air increases. The signal generator may comprise a threshold sensing device for the charge on a condenser fed by switch means controlled by the rotary member. The signal generator may comprise a computing device operated by pulses controlled by the rotary member.

摘要： A method for determining an imbalance of at least one cylinder in an arrangement of at least two cylinders in a system is provided, which includes an internal combustion engine, the imbalance of the at least one cylinder being present in relation to at least one property of an exhaust gas of the internal combustion engine and the determination of the imbalance of the at least one cylinder occurring with a sensor device for detecting at least one property of the exhaust gas of the internal combustion engine. A diagnostic threshold is ascertained through a dynamic characterization of the system with the sensor device, the dynamic characterization taking place after an excitation of the system. The diagnostic threshold makes it possible to delimit a range of potential erroneous detections which are caused due to a dispersion of an evaluating signal resulting from the imbalance of the at least one cylinder.

摘要： A method of phasing the opening and closing of internal combustion engine intake and exhaust valves relative to the rotation of the crankshaft is based upon changes in engine speed, engine load and ambient relative humidity. During certain conditions of higher humidity, in order to maintain good combustion stability and thus overall engine operation, it is necessary to reduce intake and exhaust valve overlap by adjusting the phase of the intake and exhaust camshafts. This is achieved by utilizing a set of cam position reference values and constraints based upon engine speed, engine load and humidity that are contained in lookup tables that adjust and limit cam position and valve overlap. Generally speaking, in order to maintain optimum engine performance, intake and exhaust valve overlap is reduced with higher ambient humidity and vice versa.

摘要： For example, during an acceleration transient period of time during which a demand load is raised, a supercharging pressure is raised before a mechanical compression ratio is lowered and an internal combustion engine falls in a high load state. At this time, there is a possibility that a generation of knocking and an excessive rise in a cylinder inner pressure occur. This possibility is a task to be solved. The internal combustion engine includes: a variable compression ratio mechanism which is capable of modifying the mechanical compression ratio; a turbo charger (2) which supercharges intake air utilizing an exhaust energy; and an exhaust bypass valve (7) which adjusts a supercharging pressure as a supercharging pressure adjustment mechanism. The mechanical compression ratio is detected by a control shaft sensor (34) and the supercharging pressure is limited on a basis of this mechanical compression ratio.
