Abstract: PURPOSE:To prevent a spark plug from smoldering as well as to keep off an output drop and a worsening of emission control, by making reduction speed of accelerating increment quick in time of low temperature but slow in time of high temperature, respectively. CONSTITUTION:When an accelerating state of an engine (a) is detected by a detecting device (b), a fuel injection quantity is increased by an increasing device (d) according to engine temperature (c) at that time, and in this case, it is increased much in time of low temperature but less in time of high temperature. At the time of reducing an accelerating increment value by a reduction device (e), this reduction speed is controlled according to the engine temperature (c). That is to say, in time of low temperature, it is reduced quickly but in time of high temperature slowly. With this constitution, smoldering in a spark plug due to excess fuel injection is preventable from occurring and, what is more, a tendency of making an air-fuel ratio, in time of acceleration, into being lean is also preventable.

Abstract: PURPOSE:To prevent knocking from occurring, by increasing a fuel injection quantity by degrees from that point that an engine comes into a state of being high load up to the specified increment value. CONSTITUTION:That whether an engine (a) comes into a state of being high load or not is detected by a high load state detecting device (b). And, in time of a high load state, a fuel injection quantity is gradually increased up to the specified increment value from that point that the engine goes into a state of being high load. Since an air-fuel ratio is controlled in a rich direction in accord with a rise of temperature in an engine combustion chamber, knocking is preventable from occurring. In addition, at an interval till the fuel injection quantity reaches the specified increment value, a rate of fuel consumption is improved.

Abstract: PURPOSE:To reduce the disorder of an air-fuel ratio in time of fuel cutting, by setting two kinds of fuel-cut engine speed setting values and, when an engine speed goes beyond the first setting value, cutting fuel for a half number of cylinders while if it exceeds the second value, cutting the fuel for all cylinders. CONSTITUTION:In order to prevent an engine from overrunning, a first fuel-cut engine speed and a second fuel-cut engine speed being larger than the former both are set at a fuel-cut controller. And, when an engine speed exceeds the first setting speed, a half number of cylinders alone are subjected to fuel cut. And when the engine speed goes beyond the second setting speed, fuel for all cylinders is cut. With this constitution, the disorder of an air-fuel ratio at every cylinder in time of fuel cutting is well reduced and, what is more, hunting width in the engine speed is reducible.

Abstract: PROBLEM TO BE SOLVED: To provide an internal combustion engine control system and its method for improving emission at starting an internal combustion engine. SOLUTION: When engine starting conditions are established at a time t0, a motor MG1 monitors the engine. Then, at a time t1, fuel is injected in a fuel injection amount calculated in accordance with an intake air amount Q and a theoretical air-fuel ratio and a mixture is ignited for combustion. At this time, the amount of exhaust gas is less than in normal idling operation because the intake air amount Q is the minimum air amount Qmin such that a friction equivalent qfri is subtracted from an idling air amount Qidl and it is enough for combustion with no misfire. An idling speed cannot be sustained only by the engine and so it is sustained by the torque of the motor MG1. After a time t1, a catalyst floor temperature Tcat rises and gets to a floor temperature specified value Tcatref at a time t2. Then, an exhaust gas purifying catalyst develops sufficient purifying performance to make the engine into independent operation with the intake air amount Q as the idling air amount Qidl.

解决方案：当在时间t0建立发动机起动条件时，电动机MG1监视发动机。 然后，在时刻t1，以按照进气量Q和理论空燃比计算的燃料喷射量喷射燃料，并点燃燃烧混合物。 此时，由于吸入空气量Q为最小空气量Qmin，因此从空转空气量Qid1中减去摩擦当量qfri，因此排气量比正常怠速运转时要小 失火。 怠速不能仅由发动机维持，因此通过马达MG1的扭矩来维持。 在时间t1之后，催化剂底板温度Tcat在时间t2上升并达到地板温度指定值Tcatref。 然后，排气净化催化剂形成足够的净化性能，使得发动机作为空转量Qid1以进气量Q独立运转。 版权所有（C）2006，JPO＆NCIPI
