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 controller 300 is provided, which increases the rotation speed of the internal combustion engine when the throttle open degree detected by a throttle open degree detector 22 which detects the throttle operation by the rider is a predetermined value or lower, and it is judged that the hull 1 is running based on the rotation speed of the engine 2 detected by the rotation speed detector 24, and when a steering handle angle detector 21 detects that the rider performs the risk avoidance operation.
Claims12
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:
- rotation speed detecting means which detects a rotation speed of the internal engine;
- throttle operation state detecting means which detects a state of the throttle operated by a rider;
- risk avoidance operation detecting means which detects that the rider operates an operation for risk avoidance;
- and
- controlling means which increases the rotation speed of the internal combustion engine, when, in a case where a throttle open degree detected by the throttle operation state detecting means is a predetermined value or lower, and it is judged that the jet propulsion type watercraft is running based on the rotation speed of the internal combustion engine detected by the rotation speed detecting means, the risk avoidance operation detecting means detects that the rider performs the risk avoidance operation.
