摘要： A fuel injection system for an internal combustion engine is provided which calculates the quantity of fuel required to bring the pressure in a fuel accumulator into agreement with a target pressure and then control an operation of a high-pressure pump based on the required quantity. Even in the absence of a change in pressure in the accumulator, the system controls the high-pressure pump based on the required quantity. Specifically, the system calculates a feedback fuel quantity required to compensate for a difference between the required quantity and a quantity of the fuel actually supplied to the accumulator, in other words, leans such a quantity difference to correct the required quantity, thus resulting in an enhanced response of the system to control the high-pressure pump to a change in pressure in the accumulator.

摘要： An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with at least one of a combustion parameter or a controlled variable arithmetic expression. The combustion parameter arithmetic expression defines combustion conditions of the engine needed to achieve required values of engine output-related values such as exhaust emissions. The controlled variable arithmetic expression defines how to operate actuators for an operation of the engine to meet desired combustion conditions of the engine. The use of the combustion parameter or controlled variable arithmetic expression achieves simultaneous agreement of the engine output-related values with required values without mutual interference between combustion parameters associated with the combustion conditions. The engine control apparatus also works to correct target values of fuel injection-related combustion parameters based on a response delay of an air-related combustion parameter, thereby ensuring the accuracy in achieving required values of the engine output-related values.

摘要： An actual maximum fuel injection rate is computed based on a falling waveform and a rising waveform of the fuel pressure. The falling waveform represents the fuel pressure detected by a fuel sensor during a period in which the fuel pressure increases due to a fuel injection rate decrease. The rising waveform represents the fuel pressure detected by the fuel sensor during a period in which the fuel pressure decreases due to a fuel injection rate increase. The falling waveform and the rising waveform are modeled by modeling functions. A reference pressure is computed based on pressure during a specified time period before the falling waveform is generated. An intersection pressure is computed, at which the straight lines expressed by the modeling functions intersect to each other. The maximum fuel injection rate is computed based on a fuel pressure drop from the reference pressure to the intersection pressure.

摘要： A learning device changes each of multiple parameters to an increased side and to a decreased side with respect to a reference value set for each of the multiple parameters. The learning device calculates an approximation degree for each combination of the changes of the multiple parameters. The learning device performs update by using the combination of the changes providing the highest approximation degree among the approximation degrees as the combination of the updated reference values when an update end condition is not satisfied. The update end condition is a condition that the approximation degree at the reference values is higher than any of the approximation degrees after the change. The learning device decides the reference values as learning values of the multiple parameters when the update end condition is satisfied.

摘要： A fuel injection system designed to execute a learning operation to spray fuel through a fuel injector in a cycle to calculate an average of actual injection quantities for correcting an injection duration so as to minimize a deviation of the average from a target quantity. The system samples the actual injection quantities for a given period of time made up of a first and a second time section. In each of the first and second time sections, the system decides whether each of the actual injection quantities is suitable for use in calculating the average or not. When a desired number of the actual injection quantities decided to be suitable for the calculation of the average has been derived in the first time section, the system proceeds to the second time section to calculate the average. This enhances the accuracy in determining the quantity of fuel actually sprayed from the fuel injector.

摘要： An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with a controlled variable arithmetic expression which defines correlations between a plurality of combustion parameters and a plurality of controlled variables of actuators for control of an operation of the engine to calculate a combination of command values to be outputted to the actuators for regulating the controlled variables needed to achieve target values of the combustion parameters. When one of the command values is produced outside an allowable operation range of a corresponding one of the actuators, the engine control apparatus corrects or limits the one of the command values to an upper or a lower limit of the allowable operation range, thereby ensuring the stability in bringing engine output characteristics close to desired values.
