Abstract: 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.

Abstract: 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.

Abstract: 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 (step 110). 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 (step 112).

Abstract: A control device for controlling an internal combustion engine comprises a multi-core type processor. As shown in Figure 2, a common element is allocated to core 1, element #1 to element #n are allocated to core 2 to core n+1, and an overall correction element is allocated to core n+2. Element #1 to element #n are unique elements that are respectively independent. The common element and the overall correction element are elements that are dependent to element #1 to element #n. By separating a plurality of elements in accordance with properties of the operations and allocating the elements to different cores in this manner, it is possible to satisfy not only demands with respect to individual actuators, but also to satisfy comprehensive demands with respect to all the actuators.
