摘要： An air-fuel ratio control system for an internal combustion engine wherein a control unit is provided for producing a basic fuel quantity signal based on an engine operating condition. The system includes a feedback system including an O.sub.2 sensor provided in the engine exhaust passage for producing an ON-OFF type signal based on the oxygen content in the engine exhaust gas. The control unit produces a feedback signal which is based on the signal from the O.sub.2 sensor. The control unit further performs a learning control by providing supplementary signals periodically based on the average value of the feedback control signal and the gain of the feedback control is decreased as the learning progresses.

摘要： An engine intake system having primary and secondary intake passages leading to the same combustion chamber. The secondary intake passage is provided with an auxiliary throttle valve which is opened under a relatively high load engine operation. The primary and secondary intake passages are respectively provided with first and second fuel injection valves which are controlled by an electronic control unit in accordance with engine operating conditions. The electronic control unit functions to determine a basic fuel supply quantity based on the intake airflow and the engine speed and modify the basic quantity by a compensation factor which is obtained from a compensation map. The compensation map is divided into two zones, the first zone substantially corresponding to the engine operating condition wherein the auxiliary throttle is closed, the second zone substantially corresponding to the engine operating condition wherein the auxiliary throttle valve is opened. The compensation factors in the second zone are determined taking into consideration the difference between the suction pressure at the first fuel injection valve and that at the second fuel injection valve. The second fuel injection valve is operated in the engine operating condition wherein the compensation factor in the second zone is selected.

摘要： An intake system for an internal combustion engine has a primary intake passage and a secondary intake passage both leading to a combustion chamber and respectively having a primary fuel injecting valve and a secondary fuel injecting valve. A control valve is provided in the secondary intake passage for closing the same under light load engine operation and opening the same under heavy load engine operation so that the intake mixture is introduced into the combustion chamber only through the primary intake passage under light load engine operation and through both the primary and secondary intake passages under heavy load operation. A control unit is provided for operating the primary and secondary fuel injecting valves in accordance with the engine operating condition so that fuel is injected only through the primary fuel injecting valve under light load operation. The control unit functions to decrease the quantity of fuel supply for a predetermined time period when it is detected that the fuel supply through the secondary fuel injecting valve is interrupted to thereby prevent the mixture from being momentarily enriched.
摘要翻译：一种用于内燃机的进气系统具有一个进气通道和一个二次进气通道，两个进气通道和二次进气通道都通向燃烧室，分别具有一次燃料喷射阀和二次燃料喷射阀。在轻负载发动机运转中，在次级进气通道中设有一个控制阀，用于在轻负载发动机运行下关闭该进气通道，并在轻负载发动机运转下将其打开，使得进气混合物仅在轻载发动机运转时才通过主进气通道被引入燃烧室并在重载运行下通过主进气通道和次进气通道。提供控制单元，用于根据发动机运行状况操作主燃料喷射阀和辅助燃料喷射阀，使得仅在轻负载运行时仅通过主燃料喷射阀喷射燃料。当检测到通过二次燃料喷射阀的燃料供给被中断时，控制单元用于在预定时间段内减少燃料供应量，从而防止混合物瞬间富集。

摘要： A method and apparatus for electronically controlling injection of fuel into an engine selectively uses fuel injection control based on an intake air flow rate sensing system (e.g. L-J system fuel injection control) and fuel injection control based on a speed density system (e.g. D-J system fuel injection control), this depending upon the amount of intake air. In an engine operating region where a control relationship between these two forms of fuel injection control is constant, e.g. in an operating region where the amount of intake air is low, the relationship is stored. In a region of high air intake, where the relationship no longer holds, the amount of fuel injection in the speed density system is corrected on the basis of the aforementioned relationship.
