Publication number: 20180086205Abstract: When start control is initiated, the start control device operates in a first operating mode in which an upper limit value of an engine speed is limited to a first upper limit value (NErev1) that is lower than an upper limit value (NErev0) in a non-start control. When an elapsed period of time after a throttle opening has exceeded a predetermined opening in the first operating mode reaches a predetermined standby time, the start control device operates in a second operating mode in which the upper limit value of the engine speed is limited to a second upper limit value (NErev2) that is lower than the first upper limit value. The start control device transitions to an ordinary mode to thereby terminate the start control when a period of time of the second operating mode reaches a predetermined control period of time or a forced cancellation condition holds.Type: ApplicationFiled: September 25, 2017Publication date: March 29, 2018Inventors: Katsumi Koyama, Hideki Uematsu, Fuyuki Kobayashi, Isao Azumagakito, Katsumi Yamamoto, Kazumasa Ogino
