    Abstract: PROBLEM TO BE SOLVED: To provide an engine electronic device for stably cleaning exhaust gas in restarting an engine after the engine is stopped in the middle of execution of an active control, and to provide a vehicle mounting the engine electronic device thereon. SOLUTION: When an active control routine is interrupted in stop of an engine before the restart of the engine (Yes in S206, S208, S210), OSC of an exhaust catalyst is compared with a predetermined neutral range in the interruption of the active control (S216), and an injection amount TAU in restart is determined based on the comparison result to perform a fuel injection control (S216 to S226). Since the OSC occluded by the exhaust catalyst is easily influenced by a condition in the interruption of the active control compared with influence of air flowing in the exhaust catalyst in the engine stop, the OSC occluded in the exhaust catalyst can be regarded as the OSC in the interruption of the active control with very few problems in accuracy.

    解决方案：在发动机重新启动之前中断发动机的主动控制程序时（S206，S208，S210中为“是”），将排气催化剂的OSC与预定中断范围进行比较 基于进行燃料喷射控制的比较结果来决定主动控制（S216）和再起动时的喷射量TAU（S216〜S226）。 由于与发动机停止时的排气催化剂中的空气流动的影响相比，由排气催化剂吸留的OSC容易受到主动控制中断的条件的影响，因此封闭在排气催化剂中的OSC可以被认为是OSC 主动控制的中断精度很少的问题。 版权所有（C）2005，JPO＆NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a cooling device for an internal combustion engine which prevents a sudden temperature fall of cooling water circulating in the internal combustion engine. SOLUTION: A warming-up control means 50 controls a pump 38 for a heat accumulation tank and a three-way selector valve 30 and warms up the engine by supplying the hot cooling water pooled in the heat accumulation tank 36 to the engine 10. When temperature of the cooling water returned from a heater core 44 to the engine 10 is below that of the cooling water discharged from the heat accumulation tank 36, the warming-up control means 50 controls the three-way selector valve 30 and adjusts a flow rate of the cooling water circulating through the heater core 44 and the engine 10 below a predetermined flow rate.

    Abstract: PROBLEM TO BE SOLVED: To surely start an engine when the engine is cranked by a motor according to the discharge of a battery. SOLUTION: The lower the temperature T of cooling medium for cooling the engine in the condition of the engine and the lower the remaining capacity SOC in the condition of the battery, the lower the target cranking speed N* of the engine is set, and the motor is driven by using a power from the battery at the target cranking speed N* to perform the cranking of the engine. Thus, since the power of the battery is assured so that the engine can be re-started after the engine fails to start, the engine is more surely started. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a rotation speed control device for an internal combustion engine favorably controlling the rotation speed, even if performing a feedback control of the rotation speed of the internal combustion engine in a condition directly connected to a driving wheel. SOLUTION: In a driving system of a hybrid vehicle, a crankshaft 10a of the internal combustion engine 10 is directly connected to the driving wheel 15 via a power division mechanism 13. An ECU 16 performs the feedback control of the rotation speed by regulating the throttle opening using a feedback correction term eqi calculated according to a deviation between the actual rotation speed ene and the target rotation speed entcal of the internal combustion engine 10. Wherein the ECU 16 finds feedback correction terms eqi1-eqi3 for every three operation regions divided according to the car speed so as to control the rotation speed using the feedback correction term in the operation region corresponding to the car speed at that time.

    Abstract: PURPOSE:To improve the fuel consumption rate at the time of a shift change through reduction in the HC (Ce) emission, and enhance the drivability after shift change through increase in the torque followed by a feel of acceleration. CONSTITUTION:When no shift change is made, calculation is made of an STPM value which is a required EGR value in step 402, and EGR performance is controlled in accordance with this STPM value (step 413). When shift change is made and if EGR is in 'on' region, EGR control is similarly performed (step 405, 413) in accordance with the required EGR value, or the STPM value. If EGR is in 'off' region, during a specified time length (C

    Abstract: PURPOSE:To prevent occurrence of knocking to aim at enhancing the economy of fuel consumption and the performance of an engine, by providing a control circuit for changing a maximum value limiting the spark retarding amount in accordance with a variation in the air-fuel ratio which is controlled by an air-fuel ratio control means. CONSTITUTION:An air-flowmeter 10 is disposed downstream of an air cleaner. The air flowmeter 10, an intake-air temperature sensor 12, a throttle sensor 24A, a knocking sensor 36, a cylinder discriminating sensor 46, a rotating angle sensor 48, a cooling water temperature sensor and an exhaust gas temperature sensor 50 are connected to a control circuit 45. An ignitor 44 and a fuel injection valve 26 are controlled in accordance with a control signal delivered from the control circuit 45. When it is discriminated that temperature of exhaust gas is below a predetermined value, a maximum value for limiting the spark retarding amount is increased by a constant value. Further, the compensation spark retarding amount is limited to such a maximum value so that a value which obtained by subtracting the compensating spark retarding amount from a basic spark advancing amount is used as an executive spark advance. With this arrangement, it is possible to prevent occurrence of knocking, thereby it is possible to aim at preventing an engine from being damaged, and at enhancing the economy of fuel consumption and performance of the engine.

    Abstract: PURPOSE:To keep off an abnormal rise in exhaust-gas temperature even at time of acceleration or the like from medium load continuation as well as to aim at improvement in fuel consumption and engine output, by setting a fuel increment value to the large value at the initial stage at a time when the exhaust-gas temperature becomes higher than the target one, and afterward attenuating it to the small value the other way. CONSTITUTION:A control circuit 10 operates a fundamental fuel injection quantity on the basis of a suction air quantity out of an air flow meter 3 and an engine speed out of crank angle sensors 5 and 6 and also performs varieties of compensation on the basis of each detection value of a water temperature sensor 13, an oxygen sensor 14, an exhaust-gas temperature sensor 18, etc. The control circuit 10 increases a quantity of fuel as much as 50% or so at the first point that exhaust-gas temperature becomes more than about 800 deg.C, and afterward a fuel increment rate at time of normal exhaust-gas high temperature is attenuated to 30% or so each about 100ms at the specified attenuation factor.
