摘要：【課題】船速センサやプロペラ回転速度センサを不要として、シフトチェンジに際して動力源や動力伝達機構にかかる負荷を低減できるようにする。【解決手段】船外機の制御装置100において、演算部103は、シフト操作がフォワードからニュートラル方向への操作である場合、アクセル開度の全閉後であってシフト機構がフォワードからニュートラルに切り替わる前のタイミングを起算点とし、起算点でエンジン回転速度検出器26によって検出されるエンジン回転速度に基づいて、模擬船速としてのエンジンの回転速度の時系列変化を推定演算する。制御部104は、シフト操作がフォワードからニュートラルを経てリバースに至る操作である場合、演算部103によって推定演算する模擬船速が所定の閾値以下になるまでシフト機構をニュートラルに維持し、その後リバースに切り替えるように電動アクチュエータ19を制御する。【選択図】図3

摘要： PURPOSE:To make uniform distribution of wake flowing into a propeller and efficiently reduce a propeller vibrating force, by discharging sea water out of a wake acceleration discharge port formed at a stern portion under a sea level and at the front of the propeller. CONSTITUTION:A wake acceleration discharge port 2 is formed at an upper portion of a stern portion of a hull 1 under a sea level and at the front of a propeller 5. A water intake opening 3 is formed at an outer board portion of the hull at a forward position of the discharge port 2. The discharge port 2 and the water intake opening are communicated with each other through an inboard pipe 4. Accordingly, sea water induced from the water intake opening 3 is fed through the inboard pipe 4 to the discharge port 2, from which the sea water is discharged. Such a discharge water acts to accelerate large wake over a propeller disk, thereby making uniform distribution of wake at the propeller disk A.

摘要： PURPOSE: To diffuse a large quantity of exhaust gas bubbles at the periphery of blade parts and contrive to enhance starting accelerating property, by a method wherein an ON-OFF valve which is closed under the action of a centrifugal force of not smaller than a predetermined value is provided in a through- hole.
CONSTITUTION: At the time of a starting acceleration, a propeller 19 is rotated at a low speed, and a centrifugal force exerted on a valve body 30 is small, so that the propeller is maintained in the direction opposite to a valve seat 31 by an energizing force of a spring 32, and the through-hole 28 is maintained in a conducting state. Accordingly, a large quantity of an exhaust gas flows out to the outer peripheral part of a boss part 22 through an exhaust gas passage 26 and the through-hole 28, a large quantity of exhaust gas bubbles are diffused to the periphery of the blade parts 21, whereby the resisting force exerted from water to the propeller 19 at the time of the starting acceleration is reduced, and acceleration can be promoted. At the time of normal steaming, the through-hole 28 is maintained in a non-conducting state, whereby diffusion of exhaust gas bubbles to the periphery of the blade part 21 is eliminated, and an or iginally expected thrust can be obtained.

摘要翻译：目的：为了在叶片部件周围扩散大量排气气泡，提高起动加速性能，通过一种方法，其中在离心力不小于预定的离心力的作用下关闭的开关阀通孔中提供了数值。构成：在起动加速时，螺旋桨19以低速旋转，施加在阀体30上的离心力小，螺旋桨沿与阀座31相反的方向被维持在弹簧32的通电力，通孔28保持导通状态。因此，大量废气通过排气通路26和通孔28流出到凸台部22的外周部，大量的排气气泡扩散到叶片部的周围由此，在起动加速时从水施加到螺旋桨19的抵抗力降低，能够促进加速。在正常蒸汽时，通孔28保持在非导通状态，从而消除了排气气泡向叶片部分21的周边的扩散，并且可获得或预期的推力。
