摘要： A fuel supply control system for an internal combustion engine having a throttle body, and a fuel injection valve arranged in an intake manifold upstream of the throttle body for supplying fuel to all cylinders. An air throttle valve has a valve body having a notched opening formed therein and disposed to be opposite the nozzle of the fuel injection valve to increase the flow speed of intake air in the vicinity of the nozzle when the air throttle valve is fully closed. An electronic control unit controls the fuel injection valve in response to operating conditions of the engine. The electronic control unit causes the air throttle valve to be fully closed when a predetermined low rotation-speed operating condition of the engine, in which at least the rotational speed of the engine is lower than a predetermined value, is satisfied. The predetermined value of the rotational speed of the engine is set such that the lower the atmospheric pressure the smaller the predetermined value.

摘要： An adaptive charge mixture control for an internal combustion engine includes four input signals supplied to an OR gate to generate a net "go rich" signal supplied to a servo motor controlling an air/fuel charge mixture control valve for an internal combustion engine. The servo is also supplied with a "go lean" fixed signal tending to lean out the air/fuel mixture. The four "go rich" signals include a first signal derived from a comparison of engine speed with a predetermined minimum (i.e., idle) level; a second signal derived from comparing throttle positions with a preset minimum throttle position; a third signal derived from comparing engine deceleration rate with a preset engine deceleration rate; and a fourth signal derived from a measurement of engine instantaneous power output.

摘要： An amount of fuel to be supplied to an internal combustion engine is determined in dependence upon operating conditions of the engine and is corrected by a correction variable dependent upon atmospheric pressure. The correction variable is set so as to increase with a decrease in atmospheric pressure, and the set value of the correction variable is modified so as to decrease with a rise in the engine rotational speed. The correction variable resulting from this modification is added to the amount of fuel to be supplied to the engine to correct the same.

摘要： The sonic dispersion system includes a sonic dispersion unit (18) mounted upon a mounting assembly (100,102) and having an active surface (116) with a central apex (120) positioned in spaced relationship to the mounting assembly. Material directing units (92,94) direct material against the active surface so that the material is redirected thereby toward the apex. The sonic dispersion unit (18) may be used in combination with a control system (10) which controls the amount of material provided from two separate material sources (14,34).

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。
