    摘要: When a throttle is fully open, a maximum torque set value is corrected based on the ratio between the maximum air volume set value under fully-open throttle conditions and the actual maximum air volume detected by an intake air volume meter such as an air flow sensor. Based on the corrected maximum torque set value, both the relation between the degree of accelerator opening and target torque and the relation between the target torque (target air volume) and the degree target throttle opening are corrected. Thus, even when various types of disturbances relating to torque error are generated, such as variations in air density generated in association with variations in temperature or altitude, variations over time such as contaminations of throttle chambers, or difference between machines such as engine bodies or auxiliary machines, it is possible to generate actual torque with respect to a target torque with a high degree of accuracy, while maintaining a desired relation between the degree of accelerator opening and the throttle opening.

    摘要: An object is to provide a control device and control method for a compressed self-ignition type internal combustion engine, which can reduce torque variation due to misfire when the air-fuel ratio varies during compressed self-ignition type combustion, and thereby effectively use the potential for reducing fuel consumption. As the combustion mode, a spark-ignition type combustion mode by use of an ignition plug and a compressed self-ignition type combustion mode which utilizes a pressure increase in a combustion chamber in association with upward movement of piston are selectively set depending on an operational state of the engine, and when the air-fuel ratio in the compressed self-ignition type combustion mode is rich, a regional upper limit of the compressed self-ignition type combustion region is changed toward the lower engine torque side, and when the air-fuel ratio is lean, the regional upper limit is changed toward the higher engine torque side.

    摘要: In an engine controller capable of carrying out spark ignition type combustion and compressed self-ignition type combustion, in order to suppress operation performance deterioration and exhaust performance deterioration at the time of switching a combustion mode from the compressed self-ignition type combustion to the spark ignition type combustion, intake pipe pressure downstream a throttle is quickly reduced by making the throttle opening degree smaller than a target throttle opening degree of the spark ignition type combustion immediately after switching for a certain period during the combustion mode is switched from the compressed self-ignition type combustion to the spark ignition type combustion. As a result, responsiveness of an intake amount at the time of switching the combustion mode from the compressed self-ignition type combustion to the spark ignition type combustion is enhanced, and combustion switching without exhaust deterioration and torque variation is realized.
