摘要： Energizing interval of an ignition coil, which is basically determined on the basis of the rotational speed of an engine, is corrected by adding thereto an extension amount which is either a function of the rotational speed of the engine or a given upper limit value at the rotational speed of the engine when accelerating condition is detected. Thus, the ignition coil is supplied with a primary winding current for a desired interval even during acceleration so that sufficient ignition voltage will be produced to properly ignite air/fuel mixture in engine cylinders. The extended energizing interval is then reduced stepwise to provide normal energizing interval during engine operations other than acceleration.
摘要翻译：基本上基于发动机的转速确定的点火线圈的通电间隔通过加上与发动机的转速或给定的上限值的函数相对应的扩展量来校正检测到加速条件时发动机的转速。因此，即使在加速期间，点火线圈也被提供一段期望的间隔的初级绕组电流，从而产生足够的点火电压以适当地点燃发动机气缸中的空气/燃料混合物。然后，延长的激励间隔逐步减小，以在加速之外的发动机操作期间提供正常的通电间隔。

摘要： The cross-sectional area of a bypass passage around a throttle valve in an intake passage of an internal combustion engine is additionally increased by a predetermined value only when the throttle valve changes from an open position to the fully closed position during a heavy load condition or during a transitional condition from the heavy load condition to a light load condition. Therefore, the flow rate of the intake air at deceleration is not additionally increased during a light load condition, since that would cause the operation of the engine to be stable during deceleration.
摘要翻译：仅在节气门在重负载状态期间从打开位置变化到完全关闭位置时，内燃机的进气通道中的节流阀周围的旁通通道的横截面面积额外增加预定值，或在从重负载状态到轻负载状态的过渡条件下。因此，在轻负载状态下，减速时的进气量的流量不会增加，因为这将导致发动机的运转在减速期间稳定。

摘要： A spark advance angle is calculated depending upon the flow rate of air sucked into the engine or the pneumatic pressure in the intake manifold and upon the rotational speed of the engine. When the actual engine temperature exceeds a predetermined value higher than the engine temperature at the normal operating condition of the engine, the calculated spark advance angle is corrected to decrease.

摘要： According to the present invention, an amount of fuel being supplied to an internal combustion engine during acceleration is controlled in association with a desired value of acceleration (a degree of acceleration) and a temperature of the engine. The amount of fuel being supplied increases, as the desired value of acceleration is increased, and as the engine temperature becomes lower. Thus, an engine output necessary for rapid acceleration is positively provided, with the assurance of a desirable driving feeling at slow acceleration.

摘要： In a diesel engine having a rotational angle sensor for detecting the engine speed, when the rotational angle sensor is in an abnormal state, a fuel-cutting operation is performed. A first fuel-cutting operation is immediately performed so as to indicate to the driver that an abnormal state exists. However, subsequent fuel-cutting operations after restarting of the engine are delayed as compared with the first fuel-cutting operation.

摘要： A fuel injection pump for a diesel engine includes an input shaft rotated with the crankshaft, and a housing and a plunger which slides in a bore formed in the housing and is coaxial with the input shaft, with a high pressure chamber being defined at an end of the plunger between it and the bore. The plunger rotates with the input shaft and reciprocates so as to pump fuel at high pressure from the high pressure chamber to the engine cylinders, under the control of an electrically actuated electromagnetic valve, comprising a solenoid coil, which selectively vents the high pressure chamber according to the control of a control means, so as to provide fuel injection in appropriate amount to the diesel engine. There is provided a means for determining whether or not the voltage across the solenoid coil of the electromagnetic valve, when supply of power thereto changes from the ON to the OFF condition, rises higher than a certain value, or not. If a determining means detects that this voltage across the solenoid coil has not so risen, this lack of high transient voltage spike indicating that the solenoid coil may be discontinuous or functioning abnormally, then the engine is restrained. This restraint may consist of interrupting fuel flow to the engine to totally stop it, or of restricting air intake to the engine so as to put a ceiling on its rotational speed.

摘要： The amount of fuel supplied to the engine is corrected in accordance with an air-fuel ratio correction coefficient. When the engine is in a predetermined first operating condition, the correction coefficient is calculated depending upon the detected concentration of a predetermined component in the exhaust gas, and thus the above correction is performed by closed-loop control. When the engine is not in the first operating condition, the correction coefficient is fixed, and thus the above correction is performed by open-loop control. An average value of the calculated correction coefficient is calculated only when the engine is in a predetermined second operating condition. An initial value of the air-fuel ratio correction coefficient when closed-loop control is resumed is determined to be the calculated average value.
