Abstract
Official abstract text for this publication.
A throttle control method of controlling an opening degree of a throttle valve in a multi-cylinder engine that includes throttle valves in intake passages provided for each cylinder. It is possible to independently control the opening degree for each of the throttle valves. The throttle control method includes controlling the opening degree of the throttle valve is based on differences among intake air amounts in the respective intake passages.
First claim
Opening claim text (preview).
What is claimed is: 1. A throttle control method for controlling an opening degree of a throttle valve in a multi-cylinder engine that includes throttle valves in intake passages provided for each cylinder, wherein it is possible to independently control the opening degree for each of the throttle valves, the throttle control method comprising: controlling the opening degree of the throttle valve based on differences among intake air amounts in the respective intake passages; calculating an average intake air amount of the throttle valves; and controlling an opening degree of a throttle valve in a predetermined intake passage based on a difference between an intake air amount in the predetermined intake passage and the average intake air amount. 2. A throttle control method for controlling an opening degree of a throttle valve in a multi-cylinder engine that includes throttle valves in intake passages provided for each cylinder, wherein it is possible to independently control the opening degree for each of the throttle valves, the throttle control method comprising: controlling the opening degree of the throttle valve based on differences among intake air amounts in the respective intake passages, wherein an opening degree of another throttle valve is controlled to be an opening degree of a throttle valve in an intake passage having the largest intake air amount among a plurality of intake passages. 3. A throttle control method for controlling an opening degree of a throttle valve in a multi-cylinder engine that includes throttle valves in intake passages provided for each cylinder, wherein it is possible to independently control the opening degree for each of the throttle valves, the throttle control method comprising: controlling the opening degree of the throttle valve based on differences among intake air amounts in the respective intake passages, wherein an opening degree of another throttle valve is controlled to be an opening degree of a throttle valve in an intake passage having the smallest intake air amount among a plurality of intake passages. 4. A throttle control method for controlling an opening degree of a throttle valve in a multi-cylinder engine that includes throttle valves in intake passages provided for each cylinder, wherein it is possible to independently control the opening degree for each of the throttle valves, the throttle control method comprising: controlling the opening degree of the throttle valve based on differences among intake air amounts in the respective intake passages, wherein when an engine rotation speed is higher than a set range, the opening degree of the throttle valve in the intake passage having the largest intake air amount among the plurality of intake passages is controlled to be decreased, and when the engine rotation speed is lower than the set range, the opening degree of the throttle valve in the intake passage having the smallest intake air amount among the plurality of intake passages is controlled to be increased. 5. The throttle control method according to claim 4 , wherein when the engine rotation speed deviates from the set range, all throttle valves are controlled to be opened or closed at the same time. 6. The throttle control method according to claim 4 , wherein when the engine rotation speed is higher than the set range, only the throttle valve in the intake passage having the largest intake air amount among the plurality of intake passages is controlled to be closed, and when the engine rotation speed is lower than the set range, only the throttle valve in the intake passage having the smallest intake air amount among the plurality of intake passages is controlled to be opened.
