CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

In a diesel engine, displacement of an amount of fuel injection is calculated on the basis of a reference amount of heat production and an actual amount of heat production, and an amount of fuel injection from an injector is corrected on the basis of the displacement of an amount of fuel injection. Displacement of a heat production rate gradient is calculated by subtracting an actual heat production rate gradient from a reference heat production rate gradient, displacement of an amount of intake air on the basis of the displacement of heat production rate gradient and the displacement of the amount of fuel injection, and the amount of intake air is corrected by adjusting a supercharging pressure of a turbocharger on the basis of the displacement of the amount of intake air. Accordingly, it is possible to adjust the amount of fuel injection and the amount of intake air.

主权项

1. A control device for an internal combustion engine, the control device comprising:
an electronic control unit configured to a) calculate a fuel injection correction value based on a first difference, the first difference being a difference between a predetermined reference amount of heat production and an actual amount of heat production, b) control an amount of fuel injection based on the fuel injection correction value, c) calculate an intake air correction value based on a second difference and any one of displacement of the amount of fuel injection and the fuel injection correction value, the second difference being a difference between a predetermined gradient of the reference amount of heat production and a gradient of the actual amount of heat production, the displacement of the amount of fuel injection being calculated based on the first difference, and d) control an amount of intake air based on the intake air correction value.
