| abstract |
(57) [Summary] [Purpose] To prevent fluctuations in the air-fuel ratio during transient operation during purging of evaporated fuel. [Configuration] A maximum purge rate, which is a ratio of a purge amount and an intake air amount Q when the purge control valve is fully opened, is stored in advance. The duty ratio of the purge control valve is controlled, and this duty ratio PGDUTY is set to the target purge rate / maximum purge rate. The target duty ratio is gradually increased when the purge is started. When the feedback correction coefficient FAF is reduced by purging, the feedback correction coefficient F Purge A while gradually returning AF to FAF before starting purge The / F correction coefficient FPG is increased, and the injection amount is corrected by the sum of the purge A / F correction coefficient FPG and the feedback correction coefficient FAF. |
