Abstract (en)
[origin: EP0296323A2] In an engine control system comprising a plurality of sensors including a throttle opening sensor for detecting the closed state of a throttle valve, a method comprising the steps of judging wether the engine speed has decreased or not to a predetermined engine speed which is higher than a desired engine speed in an engine idle operation, when said throttle valve has been closed, and in a case that it is judget that the engine speed has decreased to said predetermined engine speed, the duty cycle of a bypass valve being controlled in accordance with the pulse from a pulse generating circuit when the real engine speed becomes lower than said predetermined engine speed.
