摘要： In a speed transition period from when an internal combustion engine is started to when an engine speed settles down to a certain speed, a compression top dead center of a cylinder first operating is set as a reference crank angle and compression top dead centers of the cylinders arriving successively after said reference crank angle in the speed transition period are set as judgment use crank angles. Reference crank angle advancing times are detected and stored in advance, wherein the reference crank angle advancing times are crank angle advancing times when a reference fuel is used, and the crank angle advancing times are times required for the crank angle to advance from the reference crank angle to the judgment use crank angles. The actual crank angle advancing times are detected. When an actual crank angle advancing time is shorter than the reference crank angle advancing time, the ignition timing is retarded by an amount corresponding to a difference of the actual crank angle advancing time from the reference crank angle advancing time. When the actual crank angle advancing time is longer than the reference crank angle advancing time, the ignition timing is advanced by an amount corresponding to the difference.

摘要： An operating condition value is acquired at the time of internal combustion engine startup. If the acquired condition value is one of a plurality of reference condition values for which optimum values are defined, the optimum value for the reference condition value is set as a fuel injection amount. If, on the other hand, the acquired condition value is other than the reference condition values, an interpolated value, which is interpolation-calculated by using the relationship between the reference condition values and optimum values, is set as a fuel injection amount. The angular acceleration for fuel injection according to the interpolated value, which is a physical quantity related to the operating performance of an internal combustion engine, is then determined to correct the interpolated value in accordance with the difference between the actual angular acceleration and target angular acceleration.

摘要： The present invention provides a catalyst temperature control device to control a temperature of a catalyst which influences emission performance of an internal combustion engine. A plurality of temperature measurement points are disposed continuously or dispersedly at least in a flow path direction inside the catalyst. The temperature measurement points can include actual measurement points where temperature sensors are disposed, and virtual measurement points where temperature sensors are not disposed. A control point is selected from the plurality of temperature measurement points in accordance with operation conditions of the internal combustion engine, and a target value of the temperature of the catalyst is set. A manipulated variable of the internal combustion engine is determined based on a difference between the temperature at the control point acquired by actual measurement or estimation and the target value, and the internal combustion engine is operated in accordance with the determined manipulated variable.
