摘要： The burning of unburned fuel in an exhaust pipe is a technique for preventing a turbo lag. However, since the technique requires combustion in the exhaust pipe, the temperature in the exhaust pipe becomes high, which is likely to damage the exhaust pipe, cause the exhaust emissions to deteriorate. The present invention addresses this problem by providing an ignition control apparatus for an engine with a turbocharger, capable of adjusting an ignition timing and a turbocharger. When a throttle valve is opened rapidly, the ignition control apparatus causes the ignition timing to advance with respect to the ordinary ignition timing. Consequently, the start of combustion is advanced, and the speed of rotation of the engine is raised, thereby increasing the speed of an exhaust turbine to achieve the desired increase in engine performance, without the problems of conventional ignition control systems.

摘要： When a large load is exerted during restraint control of an engine of a jet propulsion boat, the drop of the engine revolution frequency causes a feeling of harsh braking. An engine revolution frequency control apparatus provided to prevent this problem includes a engine revolution frequency detector for detecting an engine revolution frequency, and threshold value setting units for setting first and second engine revolution frequency threshold values. The second threshold value is set to be higher than the first threshold value. An engine control unit includes an overspeed governing capability that starts restraint control for restraining rotation when the engine revolution frequency detected by the engine revolution frequency detector is more than said first threshold value when the engine is accelerating, and terminates restraint control when the engine revolution frequency is less than a second thresholds value during deceleration.

摘要： A jet-propelled watercraft capable of maintaining a propulsion force required for a turn made at the same time as closing of a throttle valve. The jet-propelled watercraft has an auxiliary intake valve and an ECU. The auxiliary intake valve in an intake pipe opens/closes an auxiliary intake passage to bypass a throttle valve. The ECU performs control such that an opening of the auxiliary intake valve in a state where the rotation speed of the engine is not lower than a threshold value is larger than the opening of the auxiliary intake valve in a state where the engine is idling. When in a state where the rotation speed is not lower than the threshold value, it is detected that the throttle valve is completely closed and that a steering mechanism has been turned by a prescribed angle or more, a current opening of the auxiliary intake valve is maintained.

摘要： A controller that executes engine output control that a throttle is closed when a boat is navigated at a predetermined speed or higher and the output of an engine is gradually increased up to predetermined output when a steering system is steered right or left at a predetermined angle or more is provided. Thus, an overshoot phenomenon that the engine speed is held at a predetermined engine speed after the engine speed once increases up to the predetermined engine speed or higher when the engine speed is increased in deceleration can be avoided. As a result, the body of the boat can be prevented from sliding laterally to a great extent at the beginning of turning and the turning performance of the body can be enhanced.

摘要： A mounting structure is provided for an air-fuel ratio sensor on an exhaust pipe in a motorcycle in which a concentration of oxygen in an exhaust gas can be detected efficiently and accurately by the air-fuel ratio sensor. The air-fuel ratio sensor is mounted on a convergent connector of exhaust pipes, which, in turn, are operatively connected to the cylinders of a multi-cylinder engine. The air-fuel ratio sensor is located upstream of catalytic converters provided in the exhaust pipes, and may be mounted so as to be oriented substantially vertically when the motorcycle is in an upright configuration, or alternatively, may be inclined toward the rear of the motorcycle.

摘要： A control unit is provided for increasing the number of engine revolutions per minute to a predetermined number of revolutions per minute when the throttle is closed and when the engine has been rotated for more than a prescribed time period at more than a prescribed number of revolutions per minute, and the throttle has been opened for more than a prescribed time period at more than a prescribed opening. The control unit increases the number of engine revolutions per minute to a predetermined number of revolutions per minute irrespective of the throttle and maintains the same for a predetermined retention time when the steering handle is turned to the left or the right by more than a prescribed angle. The time to start controlling the number of engine revolutions per minute may be delayed by providing a delay time for delaying the time to start controlling the engine revolutions. The number of engine revolutions per minute may be controlled after the hull is underwater. As a consequence, the amount of sideslip of the jet propulsion boat can be improved. In addition, since the control unit for increasing the number of engine revolutions per minute to a predetermined number of revolutions per minute irrespective of the throttle and maintaining the same for a predetermined retention time is provided, the quantity of jet water stream is secured. As a result, the steering of the jet propulsion boat is improved.
