摘要： 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).

摘要： 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.

摘要： In an ignition timing control apparatus for an engine, a KCS learning value learned when the engine is in a given operating state is used in an ignition timing control executed when the engine is in the other operating state. An estimated knocking occurrence ignition timing is set based on a most retarded ignition timing using the KCS learning value. A final ignition timing is set by changing a KCS feedback correction value based on whether knocking occurs when ignition is performed at the estimated knocking occurrence ignition timing. When a point indicating the engine operating state moves into a region where it is difficult to set the estimated knocking occurrence ignition timing, the KCS feedback correction value is changed to retard the final ignition timing, and the final ignition timing is set using the KCS learning value and the changed KCS feedback correction value.

摘要： A throttle full-closure detecting apparatus for judging the full-closure state of a throttle valve uses the minimum value of a throttle sensor voltage so that the apparatus output is compensated for, in particular, a change in temperature. In a timer routine in the apparatus, first, the throttle sensor output is AD-converted and the thus AD-converted output is stored into a RAM and a general purpose register Ar. Next, a full-closure angle is stored in a compare register Cr and the contents of Ar and Cr are compared with each other so that when Cr>Ar, the AD-converted throttle value is stored as a full-closure angle and first storage updating is performed with the minimum throttle opening as the angle. Further, second updating for adding a specified value to the stored value of the full-closure angle is performed at a period sufficiently larger than the period of the time routine, and the first updating is made ready after the second updating.

摘要： If the pressure in a supply passage drops at a speed greater than a first determination speed in a state in which a first mode for supplying gas fuel to an internal combustion engine is selected, a control apparatus inhibits selection of the first mode. Then, the control apparatus switches from the first mode to a second mode, in energy other than gas fuel is used. In this state, if the pressure in the supply passage drops at a speed greater than a second determination speed, the control apparatus maintains the state in which the second mode is selected. If the pressure in the supply passage drops at a speed lower than the second determination speed, the control apparatus cancels the inhibition of selection of the first mode when it is detected that a manual on-off valve is opened.

摘要： A fuel injection system of an internal combustion engine in which the fuel injection amount is controlled corresponding to an atmospheric pressure change by utilizing an altitude compensating learning correction factor stored in a backup RAM. Even thought a battery is disconnected from the memory of the backup RAM and the stored data of the learning correction factor is lost, the altitude compensating learning correction factor is directly determined based on the atmospheric pressure without executing learning control so that the fuel injection amount is corrected at the time of the initial cranking of the engine.
