摘要： PROBLEM TO BE SOLVED: To provide a propelling machine for a ship to smoothly reduce the number of revolutions of an engine when a throttle valve is rapidly closed from a wide opening state. SOLUTION: This propelling machine 1 for a ship is formed such that the crank shaft 3 of a fuel injection type four-cycle engine 2 rotates a propeller 4 through a shift mechanism 11 and a throttle valve 54 is mounted on a suction pipe 52 through which air is guided in the cylinder 7 of the engine. A bypass flow passage 55 bypassing the throttle valve is formed, an ISC valve 81 is situated in the bypass flow passage. When the throttle valve is rapidly closed from a state that the valve is widely opened, the ISC valve is closed from an opening state. The closing speed of the ISC valve when a shift mechanism is switched to a neutral is decreased to a value lower than that when the shift mechanism is shifted to forward.

摘要： PROBLEM TO BE SOLVED: To enable the smooth shifting operation by lowering the revolution when a throttle valve is full closed and the revolution is not less than the specified revolution after the specified laps of time. SOLUTION: A revolution control means 100 for lowering the revolution when a throttle valve is full closed and the revolution is not less than the specified revolution after the specified time passes is provided on an engine control unit 42 of an outboard motor. The revolution control means 100 lowers the revolution by full closing an idle air adjusting valve 62 provided on a bypass passage for communicating the upstream of the throttle value with the downstream of the throttle valve on the basis of revolution information from an engine speed sensor 43. Thereafter, even if the revolution becomes the specified revolution or more, either a forward bevel gear or a reverse bevel gear of a forward/reverse selecting device is connected to a propulsion shaft, or both of them are not connected to it, and the shifting operation can be smoothly performed. The revolution control means 100 controls an ignition device 101 to delay the ignition timing, the thinned-out ignition or the ignition of any one of cylinders are stopped to easily and reliably lower the revolution.

摘要： PROBLEM TO BE SOLVED: Not to fluctuate the engine torque to the utmost, even if an air fuel ratio is changed. SOLUTION: When the ignition timing is not changed and the air fuel ratio is increased, an engine 16 has a big air fuel ratio area where a torque is dropped comparatively largely and also the sensor for detecting the air fuel ratio 57 for detecting the air fuel ratio. When the detection value H of the sensor for detecting the air fuel ratio stays in the big air fuel ratio area, the preset set air fuel ratio M is compared with the detection value detected by the sensor for detecting the air fuel ratio and when the set air fuel ratio is bigger than the detection value, the air fuel ratio is increased and also the ignition timing is quickened, while when the set air fuel ratio is smaller than the detection value, the air fuel ratio is dropped and also the ignition timing is delayed.
