Abstract: A control system for an internal combustion engine having an exhaust gas recirculation device for recirculating a part of exhaust gases to an intake system of the engine is disclosed. An estimated exhaust gas recirculation amount is calculated using a neural network to which at least one engine operating parameter indicative of an operating condition of the engine is input. The neural network outputs an estimated value of an amount of exhaust gases recirculated by the exhaust gas recirculation device. At least one engine control parameter for controlling the engine is calculated based on the estimated exhaust gas recirculation amount.

Abstract: There is provided an intake air amount control system for an internal combustion engine, which controls the amount of intake air by executing both cam phase control and valve lift control, and is capable of enhancing response and accuracy of the intake air amount control, while avoiding interaction between the cam phase control and the valve lift control. In the intake air amount control system 1, an ECU 2 controls the amount of intake air according to a target valve lift Liftin_cmd and a target cam phase Cain_cmd. The Liftin_cmd and Cain_cmd are respectively calculated as the sums of master values Liftin_cmd_ms and Cain_cmd_ms for causing an actual intake air amount Gcyl to converge to a target intake air amount Gcyl_cmd, and slave values Liftin_cmd_sl and Cain_cmd_sl set according to the master values Liftin_cmd_ms and Cain_cmd_ms (steps 56 and 64). In a lift master mode, Cain_cmd_ms is set such that Cain_cmd_ms=0 holds (step 63), and in a phase master mode, Liftin_cmd_ms is set such that Liftin_cmd_ms=0 holds (step 55).

Abstract: Work done by an engine can be accurately calculated regardless of the part in an observation section where the cylinder internal pressure signal is detected. The apparatus for calculating the work done by an engine establishes in advance correlation of phase between the cylinder internal pressure of the engine and a reference signal composed of a predetermined frequency component as a reference phase relation. A means for detecting the cylinder internal pressure of the engine for a predetermined observation section is provided. A reference signal corresponding to the detected cylinder internal pressure of the engine is calculated so that the reference phase relation is satisfied. A correlation coefficient of the detected cylinder internal pressure of the engine and the calculated reference signal is calculated for the observation section and the work done by the engine is calculated in accordance with the correlation coefficient.

Abstract: A control device for controlling an engine, comprising a variable lift mechanism capable of changing the lift of a valve and a variable compression ratio mechanism capable of changing a compression ratio in a combustion chamber. The control devise controls the variable lift mechanisms and the variable compression ratio mechanism so that, when a requested engine output is increased, a compression ratio decreasing rate is increased over a lift increasing rate and, when the requested engine output is reduced, a lift decreasing rate is increased over a compression ratio increasing rate. When the engine comprises a variable phase mechanism capable of changing the phase of the valve, the control devise controls the variable compression ratio mechanism and the variable phase mechanism so that, when the requested engine output is increased, the compression ratio decreasing rate is increased over the change rate of the phase to a delay angle and, when the requested engine output is reduced, the change rate of the phase to an advance angle is increased over the compression ratio increasing rate. Thus, the contact of the valve with a piston can be avoided.
