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： A control device acquires various requests concerning the performance of an internal combustion engine and sets a request-specific constraint on a control amount value. The constraint is expressed as a set of constraint index values assigned to individual control amount values, and the distribution of the constraint index values is varied in accordance with the type of a request. The control device integrates the constraint index values for each control amount value and then, in accordance with the distribution of the integrated constraint index value for a control amount, determines a limitation of the control amount. The control device determines a target control amount value within the limitation and controls the internal combustion engine in accordance with the target control amount.

摘要： A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.

摘要： The fuel injection amounts into each cylinder are set on the assumption that a heavy fuel will be injected during the engine starting process, and a specific torque is allowed to be generated by combustion in a specific cylinder when a fuel with a specific property between those of the heaviest fuel and the lightest fuel is injected thereinto. When the torque generated in the specific cylinder is in a range at or around the specific torque, the property level of fuel to be injected during the engine starting process is determined to be in a level range at or around the specific property. When the torque generated in the specific cylinder is higher than the range around the specific torque, the property level is determined to be in a level range on the light fuel side of the level range around the specific property.

摘要： A exhaust catalyst temperature estimating apparatus is provided for estimating a exhaust catalyst temperature of a exhaust catalyst in which a catalyst is loaded on a support and arranged in an exhaust system of an internal combustion engine. The exhaust catalyst temperature estimating apparatus estimates the exhaust catalyst temperature using a first model formula to calculate a current exhaust catalyst temperature of the exhaust catalyst based on a parameter corresponding to a current exhaust gas status. The first model formula is empirically determined such that a exhaust catalyst temperature that excludes heat generated by a chemical reaction is calculated for the parameter by using the support prior to being loaded with the catalyst, or is a physical formula of the support prior to being loaded with the catalyst such that a exhaust catalyst temperature excludes heat generated by a chemical reaction is calculated for the parameter.

摘要： A control device for an internal combustion engine which, at cold starting, enables an ignition timing retard control for warm-up of a catalyst device and a speed feedback control by means of ignition timing for converging an engine speed to a target speed includes a function for comparing a final ignition timing with a retard lower limit value, and a function for changing the target speed based upon the result of the comparing. When the final ignition timing reaches the retard lower limit value, the target speed is increased by a predetermined speed and when a difference between the final ignition timing and the retard lower limit value exceeds a predetermined angle on an advance side, the target speed is decreased by a predetermined speed. In this way, at cold starting, the engine speed is early converged to the target speed while restricting rotational variations and early warm-up of a catalyst device can be certainly realized.
