Abstract
In order to provide an internal combustion engine control unit for a jet propulsion type watercraft which can control an internal combustion engine so that a rider can perform risk avoidance safely, a throttle open degree detector 22 which detects a state of the throttle operated by a rider, and a controller 300 which, when the throttle open degree detected by the throttle open degree detector 22 is a predetermined value or lower, keeps the rotation speed of the internal combustion engine 2 at a predetermined value for a predetermined period of time after the throttle open degree has reached the predetermined value or lower, are provided.
Claims7
An internal combustion engine control unit for a jet propulsion type watercraft which runs by a jet propulsion force generated by drawing and spouting water by an internal combustion engine, comprising:
- throttle operation state detecting means which detects a state of the throttle operated by a rider;
- and
- controlling means which, when the throttle open degree detected by the throttle operation state detecting means is a predetermined value or lower, keeps the rotation speed of the internal combustion engine at a predetermined value for a predetermined period of time after the throttle open degree has reached the predetermined value or lower.
