摘要： A fuel control system for an engine has a fuel injector which injects fuel into an intake manifold of the engine. A fuel injector controller determines the amount of fuel to be injected from the fuel injector so that the sum of the amount of the direct delivery part of the injected fuel which is directly fed to a combustion chamber of the engine from the injector and the amount of the drawn part fuel which has adhered to the well surface of the intake manifold, evaporates and then flows into the combustion chamber is a target amount of fuel to be actually fed to the combustion chamber and causes the fuel injector to inject the target amount of fuel. When the controller increases the amount of fuel to be injected during acceleration, the amount of part of fuel injected from the injector which part is robbed by the wall surface of the intake manifold near the injector and does not contribute to the air-fuel ratio in intake air fed to the combustion chamber during acceleration is estimated, and the fuel injector controller increases the amount of fuel increase by an amount corresponding to the estimated amount of the part of fuel which is robbed by the wall surface of the intake manifold near the injector and does not contribute to the air-fuel ratio in intake air fed to the combustion chamber.
摘要翻译：用于发动机的燃料控制系统具有将燃料喷射到发动机的进气歧管中的燃料喷射器。燃料喷射器控制器确定从燃料喷射器喷射的燃料的量，使得从喷射器直接供给到发动机的燃烧室的喷射燃料的直接输送部分的量的总和和已经粘附到进气歧管的井表面的被抽出的部件燃料蒸发并且然后流入燃烧室是实际进料到燃烧室的目标燃料量，并使得燃料喷射器喷射目标量的燃料。当控制器增加在加速期间要喷射的燃料量时，从喷射器喷射的部分燃料的部分被进气歧管的壁表面靠近喷射器的部分被抢走并且不会有助于空燃比估计在加速期间进入燃烧室的进气，并且燃料喷射器控制器增加燃料量的增加量，其量相当于在喷射器附近被进气歧管的壁表面抢夺的部分燃料的估计量并且对进入燃烧室的进气中的空燃比无贡献。

摘要： A system for controlling idling speed of an internal combustion engine in which a speed sensor senses rotational speed of the engine. A determinator is provided for determining whether the engine is in an idling state. An output adjustor adjusts engine output when the engine is determined to be in the idling state by the determinator. A memory stores a control variable of the output adjustor in the form of a characteristic in which engine output rises approximately in proportion to a difference between a predetermined target idling speed and an actual idling speed with engine speed serving as a parameter. A control acts responsive to outputs from the determinator and the speed sensor for obtaining from the memory a control variable corresponding to engine speed at idling, and for controlling the output adjustor on the basis of the control variable. A load detector detects whether an external load is connected with the engine in operational relation; and a control variable characteristic changer changes characteristic of the control variable from the memory responsive to output from the load detector.

摘要： An automotive engine is provided with a fuel control system having a fuel injector for injecting a properly controlled quantity of fuel into cylinders of the automobile engine. The control system is adapted to cause the fuel injector to inject an increased quantity of fuel when an engine control value, relative to which the automotive engine changes its speed of rotation for a decision as to whether the automotive engine is in an acceleration state, is higher than a critical level. The control system also detects the transmission coupled to the automobile engine, and changes, when a temperature of the automotive engine is lower than a preselected temperature, the critical level according to the type of transmission detected.
