    摘要： A device for controlling an internal combustion engine capable of estimating the amount of NOx emission within short periods of time maintaining high precision and realizing improved control performance without increasing the cost as a result of not using map data in the ROM. The device includes NOx operation means 34A for estimating the amount of NOx in the exhaust gas from a theoretical formula and an empirical formula based upon the intake air amount Qa, intake air temperature To, pressure Pb, air-fuel ratio null and EGR rate null, and control means for controlling at least either the NOx purifying catalyst 17 or the combustion state in the internal combustion engine in order to lower the amount of NOx emission.

    摘要： In a fuel injection system for an engine, the degree of opening of a throttle valve provided in the suction pipe is detected with a throttle valve sensor. When the load of the engine is smaller than a predetermined value, a control unit operates to close an electromagnetic valve provided in a bypass passageway of the suction pipe, thereby setting the flow rate of air in the bypass passageway to zero or an extremely small value, whereby, when the load of the engine is higher than the predetermined value, the quantities of exhaust gases of hydrocarbon and carbon monoxide are reduced, and when the engine is under a light load, the fuel consumption is reduced.

    摘要： An engine wherein a target air-fuel ratio is changed over according to the running conditions is provided with a device for computing a target throttle opening area based on the accelerator operation and a selected air-fuel ratio. It also includes a device for correcting the throttle opening such that the throttle opening area is equal to a target throttle opening area, a device for computing a fuel amount to be provided to the engine based on the target air-fuel ratio, intake air volume and engine speed, and a device for regulating the fuel supply to the computed amount. In this way, the throttle valve opening is corrected when the air-fuel ratio is changed, fluctuations in the torque generated by the engine are smoothed out, and torque shock due to the air-fuel ratio change-over is thereby prevented.
