摘要： PROBLEM TO BE SOLVED: To enhance the accuracy of adaptation, and to simplify adaptation work.SOLUTION: An adaptation ECU 25 performs the adaptation of an engine 10 and registers an adaptation value to a memory of an engine ECU 20. The adaptation ECU 25 calculates command values of a plurality of combustion parameters by using first correlation data in which a correlation between a plurality of performance parameters and a plurality of combustion parameters is defined, and second correlation data in which the plurality of combustion parameters and a plurality of control parameters is defined, and controls the operation of the actuator. At this point, the feedback control of the performance parameter is executed so that a difference between each performance parameter and an actual value of the performance parameter may be eliminated. Furthermore, at the adaptation of the engine, the adaptation ECU 25 determines that the actual values of the plurality of performance parameters are converged with respect to an adaptation target value under a variety of operation conditions at the adaptation, and registers the command value of the control parameter in a converged state of each performance parameter to the memory as the adaptation value.

摘要： PROBLEM TO BE SOLVED: To provide an engine control device, reducing a burden of conformance test work, improving controllability to simultaneously match a plurality of sorts of engine output values with request values, and suppressing shift of actual engine output values from the request values caused by difference in response between a fuel injection system combustion parameter and an air system combustion parameter. SOLUTION: Correlation between the plurality of sorts of engine output values and a plurality of sorts of combustion parameters is defined by a combustion parameter arithmetic expression 22 to calculate combinations of target values of the plurality of sorts of combustion parameters with respect to the request values of the plurality of sorts of engine output values by using the combustion parameter arithmetic expression 22, so that the burden of conformance test work is reduced. Since the target value of the air system combustion parameter is transiently corrected based on a response delay amount of an actual value with respect to the target value of the air system combustion parameter, the actual value of the injection system combustion parameter is made to be a value suitable for the actual value of the air system combustion parameter in which delay in response occurs.

摘要： PROBLEM TO BE SOLVED: To solve a problem that there is risk that learning accuracy on deviation in the injection characteristic of a fuel injection valve is deteriorated.
SOLUTION: With respect to the injection characteristic curve information (solid line) representing the reference relationship of the variation of an injection quantity to the variation of an injection period of the injection valve, at a reference point and an additional point, learning is made on deviation amounts Δ1, Δ2 from the actual injection characteristic curve indicated by a dashed line in the drawing (the deviation amounts Δ1, Δ2 from a true value Ref at the reference point and from a true value Add at the additional point). Actual injection characteristic curve information is estimated and learned based on the learning result. After the learning, an injection period can be set based on the actual injection characteristic curve information, and desired fuel can be injected with higher accuracy.

摘要： PROBLEM TO BE SOLVED: To learn the dispersion of injection characteristics between cylinders with high precision while avoiding the unnecessary prolongation of time required for learning.
SOLUTION: When an operating state is stabilized (Step S410: YES) after shift to the i-th operating range, a learning time counter is started/updated (Step S420). In a succeeding step S430, the convergence determination of a correction quantity FCCB of dispersion in injection characteristics is made. When the convergence is determined to occur (Step S440: YES), the correction quantity FCCB is established as a learning value by turning a permission flag on in step S460. Even if not converging, the correction quantity FCCB is forcefully determined as a learning value by taking the learning time counter as a threshold TBi. When the correction quantity FCCB is determined at an early stage, surplus time is added to a threshold TB (i+1) of a next operating range.

摘要： PROBLEM TO BE SOLVED: To provide an engine control device, in which burdens of conformance test work requiring the huge numbers of tests and map preparation work are reduced and controllability of simultaneous matching of a plurality of sorts of engine output values with request values is improved. SOLUTION: Correlation between the plurality of sorts of engine output values and a plurality of sorts of combustion parameters is defined by a combustion parameter arithmetic expression 22, to acquire "an optimal combustion state for a requested engine output value".
