摘要： A small planing boat includes a multi-cylinder engine, and a propulsion unit driven by the engine for propelling a hull by drawing up and jetting out water. The engine can be configured to change the number of deactivated cylinders in a phased manner corresponding to an engine speed when the engine speed becomes a prescribed speed or more, and can include a memory for storing cylinder deactivation sequence schedules for determining sequences of cylinders that are deactivated and increasing the number of deactivated cylinders in a phased manner. An operation control device configured to deactivate the cylinders of the engine in a phased manner in accordance with the cylinder deactivation sequence schedules stored in the memory. The operation control device shifts the cylinder deactivation sequence schedules to be read out from the memory to another cylinder deactivation sequence schedule corresponding to an operational state of the engine.

摘要： A water jet propulsion watercraft includes an engine, an exhaust channel, and an engine control unit. The engine includes a combustion chamber arranged to combust fuel therein, an exhaust port arranged to discharge exhaust gas after the combustion of the fuel in the combustion chamber, an exhaust valve arranged to open and close the exhaust port, an intake port arranged to pass air and the fuel into the combustion chamber, and an intake valve arranged to open and close the intake port. The exhaust channel is connected to the exhaust port of the engine and provides a channel through which the exhaust gas, discharged from the exhaust port, flows. The engine control unit is arranged to control the engine such that at least one location in a path leading from the exhaust channel to the intake port is blocked when the engine is stopped.

摘要： A watercraft can have a controller that can change a speed mode between a speed set mode and a regular mode in response to an operation of an auto cruise switch. The controller can return the speed mode to a regular mode under various conditions. For example, but without limitation, when an engine rotational speed reaches “zero” or nearly “zero” (i.e., an engine operation stops or nearly stops) while the speed mode is in the speed set mode. The controller can be configured to follow the actuation of the cruise switch only when the switch is operated in the regular mode.

摘要： A throttle opening controller for one embodiment of a small planing boat includes: a throttle valve for changing the degree of opening in response to displacement of a throttle lever; a remaining fuel amount detector; a fuel consumption calculating means; and a throttle opening limiting means. In one embodiment, when a remaining fuel amount detected by the remaining fuel amount detector is equal to or below a preset value L1, the fuel consumption calculating means starts calculating total fuel injection amount. When a value, obtained by subtracting the total fuel injection amount from the preset value L1, is equal to or below a threshold L0, the throttle opening limiting means determines the degree of opening of the throttle valve based on an opening rate (k). An internal space of a fuel tank can be divided using a vertical partition into plural chambers. In addition, a knock sensor can be provided for an engine.

摘要： An engine control device can be capable of suppressing a rise in engine speed at starting. The engine speed can be detected by a speed sensor and a determination can be made whether the engine speed has changed from a starting mode to a normal mode. If the engine speed has changed from a starting mode to a normal mode, the difference between the engine speed and a predetermined target engine speed is calculated, and the ignition timing is controlled based on the calculated difference. The control of ignition timing can be performed when the detected value of the rotational sensor is larger than the target engine speed.
