    • The apparatus of the present invention corrects a control target value of ignition timing using a multipoint learned value AGdp(n) for compensating for a change amount of the ignition timing caused by time-dependent change of the engine and a basic learned value AG(i) for compensating for a change amount of the ignition timing caused by a factor other than the aforementioned time-dependent change of the engine. In a multipoint learning range n in which the time-dependent change of the engine influences the ignition timing to a great extent, the control target is corrected using the multipoint learned value AGdp(n) and the basic learned value AG(i). In ranges other than the multipoint learning range n, the control target is corrected using only the basic learned value AG(i). Normally, only the learning of the multipoint learned value AGdp(n) is permitted in the multipoint learning range n, and only the learning of the basic learned value AG(i) is permitted in the ranges other than the multipoint learning range n. When it is determined that there is a possibility that fuel has been fed to a fuel tank, the learning of the multipoint learned value AGdp(n) is prohibited for a subsequent predetermined period (if NO in step S103 or step S104).

    • A fuel injection control system provides a superior start characteristic of an internal combustion engine without deterioration of an exhaust emission. The internal combustion engine has a plurality of cylinders. The fuel injection control system controls a time for injecting fuel into each of the cylinders. A first reference signal is generated each time a crank shaft of the internal combustion engine rotates 360 degrees. A second reference signal is generated each time the crank shaft rotates 720 degrees. A crank angle signal is generated each time the crank shaft rotates a first predetermined angle. Fuel is supplied to the cylinders after the first reference signal is generated for the first time after the internal combustion engine is started. The fuel is sequentially injected into each of the cylinders in a predetermined order in synchronization with a rotation of the crank angle. One of the cylinders in which the fuel supplied by the first asynchronous injection means is consumed for the first time is assumed so as to set the one of the cylinders as a cylinder from which the synchronous injection is started. An assumption of the one of the cylinders is made based on a determination whether the second reference signal is generated while the crank shaft rotates a second predetermined angle after the first reference signal is generated for the first time.
    • 燃料喷射控制系统提供内燃机的优异起动特性,而不会使废气排放恶化。 内燃机具有多个气缸。 燃料喷射控制系统控制将燃料喷射到每个气缸中的时间。 每当内燃机的曲轴旋转360度时,产生第一参考信号。 每当曲轴旋转720度时产生第二参考信号。 每当曲柄轴旋转第一预定角度时产生曲柄角信号。 在内燃机起动之后第一次生成第一参考信号之后,将燃料供给到气缸。 与曲柄角度的旋转同步地,以预定顺序将燃料依次喷射到每个气缸中。 假设由第一异步喷射装置供应的燃料第一次消耗的气缸中的一个被设定为将一个气缸设定为开始同步喷射的气缸。 基于在首次生成第一参考信号之后曲轴转动第二预定角度时,基于确定是否产生第二参考信号来确定气瓶中的一个的假设。

    • The amount of fuel injection is augmented on a hot engine start by prolonging the fuel injection time or boosting the fuel pressure. For extension of the fuel injection time, a basic fuel injection time is prolonged according to a hot start fuel increment coefficient which is obtained from a two-dimentional map based on a intake air temperature stored in a memory during an engine operation (an operating intake air temperature) and the difference between the operating intake air temperature and an intake air temperature detected on restart of the engine. In case of an apparatus for augmenting the fuel injection by boosting the fuel pressure to be supplied to a fuel injector, the control pressure to be admitted into a diaphragm chamber of a pressure regulator is switched according to a two-dimentional map providing switching and unswitching conditions in terms of the difference between the operating intake air temperature and restarting intake air temperature in relation with operating intake air temperature.
    • 通过延长燃料喷射时间或提高燃料压力,燃料喷射量在热发动机起动时增加。 为了延长燃料喷射时间,基于在发动机运转期间基于存储在存储器中的进气温度的二维图形获得的热启动燃料增量系数来延长基本燃料喷射时间(操作摄入 空气温度)和操作进气温度与在发动机重起时检测到的进气温度之间的差。 在通过增加要供应到燃料喷射器的燃料压力来增加燃料喷射的装置的情况下,根据提供切换和非开关的二维图来切换要进入压力调节器的隔膜室的控制压力 关于操作进气温度与重新起动进气温度之间的差异与操作进气温度的关系的条件。
