Abstract
(EN)
Provided is an engine system in which when starting an engine, the human force of a user is applied to an input section of a manual start unit. A crankshaft rotates in a reverse direction as a result of human force being transmitted as torque to the crankshaft from a force transmission section of the manual start unit. Fuel that is injected by an injector is guided into a combustion chamber from an intake passage via an intake port as a result of an intake valve being driven during a period in which the crankshaft rotates in the reverse direction. An air-fuel mixture is subsequently ignited by a spark plug at a point in time at which a piston has not reached a compression top dead center and the air-fuel mixture is in a compressed state within the combustion chamber as a result of reverse rotation of the crankshaft. Torque from the crankshaft to the input section during forward rotation of the crankshaft is either blocked by the force transmission section or attenuated.

La présente invention concerne un système de moteur dans lequel, lors du démarrage du moteur, la force humaine d'un utilisateur est appliquée à une section d'entrée d'une unité de démarrage manuelle. Un vilebrequin tourne dans un sens inverse du fait de la force humaine transmise sous forme de couple au vilebrequin à partir d'une section de transmission de force de l'unité de démarrage manuelle. Le carburant qui est injecté par un injecteur est guidé dans une chambre de combustion depuis un passage d'admission par l'intermédiaire d'un orifice d'admission du fait de l'entraînement d'une soupape d'admission pendant une période pendant laquelle le vilebrequin pivote dans le sens inverse. Un mélange air-carburant est ensuite allumé par une bougie d'allumage au niveau d'un point dans le temps où un piston n'a pas atteint un point mort haut de compression et où le mélange air-carburant est dans un état comprimé à l'intérieur de la chambre de combustion du fait de la rotation inverse du vilebrequin. Le couple entre le vilebrequin et la section d'entrée pendant une rotation vers l'avant du vilebrequin est soit bloqué par la section de transmission de force, soit atténué.

 エンジンの始動時に、使用者の人力がマニュアル始動部の入力部に加えられる。人力がトルクとしてマニュアル始動部の動力伝達部からクランク軸に伝達されることにより、クランク軸が逆回転する。クランク軸が逆回転する期間に吸気バルブが駆動することにより、インジェクタにより噴射された燃料が吸気通路から吸気口を通して燃焼室内に導かれる。その後、クランク軸の逆回転により燃焼室内で混合気が圧縮された状態にありかつピストンが圧縮上死点に達しない時点で点火プラグにより混合気に点火される。クランク軸の正回転時におけるクランク軸から入力部へのトルクは、動力伝達部により遮断されるか、または減衰される。
