摘要： A diagnostic system for an internal combustion engine includes an in-cylinder pressure sensor and an ECU. The ECU is configured to: (a) determine whether each cylinder of the evaluation target cylinder group is a lean cylinder; (b) estimate a degree of leanness of the air-fuel ratio of the present lean cylinders when the lean cylinders are present in the evaluation target cylinder group; (c) calculate a polytropic index in an expansion stroke for each cylinder; (d) correlate relationship information for defining a relationship between the polytropic index in the expansion stroke and an air-fuel ratio index value with the polytropic index in the expansion stroke of a reference lean cylinder; and (e) calculate the difference in air-fuel ratio between cylinders on the basis of the polytropic index of the reference lean cylinder, the relationship information correlated with the polytropic index of the reference lean cylinder.

摘要： In a spark ignition type internal combustion engine that includes a variable compression ratio mechanism A capable of changing the mechanical compression ratio, and a variable valve mechanism B capable of changing valve characteristics of an intake valve or an exhaust valve, the variable valve mechanism is mechanically coupled to the variable compression ratio mechanism, and the variable valve mechanism is controlled in accordance with the compression ratio-changing operation amount of the variable compression ratio mechanism. The variable valve mechanism is coupled to the variable compression ratio mechanism without intervention of an electronic control unit. Therefore, the possibility of the interference between a piston and an intake valve resulting from an abnormality in a control system that includes an electronic control unit as an intervening unit can be eliminated.
