摘要： An engine speed calculating apparatus capable of calculating an engine speed without being affected by pulsating revolutions in a low engine speed range. A time required for a crankshaft of an engine to revolve through a predetermined angle is measured upon each completion of revolution through the predetermined angle, and an engine speed is calculated on the basis of measured result data of the time required for revolution through the predetermined angle. When the preceding calculated engine speed is determined to be lower than a predetermined engine speed, an engine speed is calculated on the basis of a time required for the crankshaft to revolve through an angle larger than the predetermined angle.

摘要： To provide an engine speed calculation apparatus which can facilitate calculation processing of the engine speed without being influenced by pulsation rotation in a low speed region of an engine. In a low speed region of an engine, a predetermined value is divided by a time required for rotation over an angle equal to a plurality of times of a predetermined angle to calculate the engine speed, but in a high speed region of the engine in which pulsation occurs less likely, the predetermined value is divided by the value equal to the plurality of times of the time required for rotation over the predetermined angle to calculate the engine speed.

摘要： An ignition timing control device for an internal combustion engine is capable of preventing shock of an engine upon rapid acceleration by suitably controlling the ignition timing of the engine. When the width of the opening of a throttle valve is kept within a specific width for a first specific time or more in a state where the opening of the throttle valve is smaller than a specific low opening and immediately after, the opening of the throttle valve is increased from the specific low opening to more than a specific high opening for a second specific time or less, it is decided that the internal combustion engine is in a rapid acceleration state. Ignition timing of the engine is therefore retarded.

摘要： An ignition timing control method and apparatus for an internal combustion engine mounted on a motor vehicle can prevent the occurrence of the knocking in the internal combustion engine. When the engine is running within a specific speed range and the transmission gear ratio is high, the control device determines that the engine is running under a condition where knocking is likely to occur. Accordingly retarding of the ignition timing in the internal combustion engine is accomplished in order to prevent knocking.

摘要： To allow an engine having an intake duct for drawing running air to produce a high output by performing appropriate fuel injection depending on dynamic pressure variations. A vehicle speed corrective coefficient calculator calculates a fuel corrective coefficient KVPLS based on a vehicle speed VPLS, and a throttle corrective coefficient calculator calculates a corrective coefficient KV&thgr;TH based on a throttle opening &thgr;TH. A corrective coefficient multiplier multiplies the fuel corrective coefficient KVPLS and the corrective coefficient KV&thgr;TH, thus calculating a vehicle speed fuel adjustment corrective coefficient KVAF. An injection time calculator calculates a basic injection time TiM based on the throttle opening &thgr;TH and an engine rotational speed Ne, and also calculates a fuel injection time Ti by reading the vehicle speed fuel adjustment corrective coefficient KVAF and correcting the basic injection time TiM. When the engine rotational speed Ne is equal to or higher than a predetermined value Ne1 and also when the transmission is shifted to a low gear position, a corrective coefficient KVAF signal is applied to the injection time calculator.

摘要： To change a fuel injection quantity to follow a throttle opening change in a low load region. A first calculator calculates a basic injection time using a throttle opening and an engine rotational speed. A second calculator calculates a basic injection time using an intake pipe negative pressure and the engine rotational speed. A selector selects the first calculator when the load is higher, and selects the second calculator when the load is lower. If the rate of change of the throttle opening is greater than a reference value, then a switcher sets the selector to select the first calculator. Thus, if the rate of increase of the throttle opening is greater than the reference value even when the load is low, the first calculator is selected.

摘要： A fuel injection control device controls the calculated fuel injection quantity depending upon the load condition of the engine such that the fuel injection quantity demanded by the engine can be established. This fuel injection quantity is determined based upon engine speed, intake air temperature, engine temperature, the atmospheric pressure of the intake air, and the throttle opening. When the detected intake air temperature is high for a high load condition of the engine, an intake air temperature correction factor is set such that the intake air temperature is less influential upon the establishment of the fuel injection quantity. Moreover, during acceleration, an acceleration incremental fuel injection quantity is calculated based upon different water temperature correction factors. When an engine temperature is low, the fuel injection quantity demanded by the engine is very large. Accordingly, the fuel injection control device utilizes a second water temperature correction factor which is set to be larger than a first water temperature correction factor at low engine temperatures. Thus, the fuel injection quantity for acceleration of the engine at low engine temperatures can be established in accordance with the demand by the engine.
摘要翻译：燃料喷射控制装置根据发动机的负载状况控制计算出的燃料喷射量，使得可以建立由发动机要求的燃料喷射量。该燃料喷射量基于发动机速度，进气温度，发动机温度，进气的大气压力和节气门开度来确定。当检测到的进气温度对于发动机的高负载状态高时，进气温度校正系数被设定为使得进气温度在建立燃料喷射量时影响较小。此外，在加速期间，基于不同的水温校正因子来计算加速增量燃料喷射量。当发动机温度低时，发动机要求的燃料喷射量非常大。因此，燃料喷射控制装置利用在低发动机温度下被设定为大于第一水温校正系数的第二水温校正系数。因此，可以根据发动机的要求来确定发动机在低发动机温度下的加速的燃料喷射量。
