Patent number: 9347417Abstract: In the process of starting by a recoil starter, a maximum value detection section of an ECM detects a maximum value of pressure (basic atmospheric pressure) in an intake pipe detected by a pressure sensor, within a predetermined range of crank angle after activation of the ECM. An idling control unit gives feedback control on an ISC valve based on engine speed detected by an engine speed sensor, to thereby keep idling engine speed at a specified value. A correction unit corrects a basic atmospheric pressure detected by the maximum value detection section based on the duty ratio of the ISC valve in idling, and uses the result as the atmospheric pressure. A storage unit 9d stores a map in which the duty ratio of the ISC valve in idling is correlated with the amount of correction to be made on the basic atmospheric pressure.Type: GrantFiled: March 18, 2013Date of Patent: May 24, 2016Assignee: SUZUKI MOTOR CORPORATIONInventors: Nobuyuki Shomura, Tatsunori Kataoka, Akinori Yamazaki
