Title:
内燃機関の制御装置
Document Type and Number:
Japanese Patent JP7309570
Kind Code:
B2
Abstract:
To provide a control device of an internal combustion engine capable of appropriately reducing a difference between demand torque and actual torque with a simple and easy configuration without the necessity of arranging a cylinder internal pressure sensor in each of cylinders.SOLUTION: A control device of an internal combustion engine for controlling a diesel engine includes an operation state detection section for detecting an operation state including an air-fuel ratio of the diesel engine, a request base injection amount calculating section for calculating a request base injection amount satisfying demand torque, a target air-fuel ratio calculating section for calculating a target air-fuel ratio when the operation state satisfies an air-fuel ratio control condition, an intake amount adjustment section for gradually decreasing an intake amount so that an actual air-fuel ratio detected when the operation state satisfies the air-fuel ratio control condition comes close to the target air-fuel ratio, a correction injection amount calculating section for estimating torque-down in correspondence with transition of the actual air-fuel ratio by the intake amount adjustment section and calculating a correction injection amount for preventing the estimated torque-down, and a final injection amount calculating section for calculating a final injection amount by adding the request base injection amount and the correction injection amount.SELECTED DRAWING: Figure 9
