Title (EN) UNIFLOW SCAVENGING TYPE TWO-CYCLE ENGINE
(FR) MOTEUR À DEUX TEMPS DU TYPE À BALAYAGE EN ÉQUICOURANT
(JA) ユニフロー掃気式2サイクルエンジン
Abstract:
(EN) This uniflow scavenging type two-cycle engine, in which exhaust gas in a cylinder is extruded from an exhaust port (142) by means of scavenging gas introduced from a scavenging port, is provided with: a valve body (144a) that openably closes the exhaust port; and a spray part (168) which sprays an incombustible fluid and is provided on the opposed surface (144c) facing a piston disposed in the cylinder.
(FR) L'invention concerne un moteur à deux temps du type à balayage en équicourant, dans lequel moteur des gaz d'échappement dans un cylindre sont chassés à partir d'une lumière d'échappement (142) à l'aide d'un gaz de balayage introduit à partir d'un orifice de balayage, et lequel comporte : un corps de soupape (144a) qui ferme de façon à ce qu'elle puisse être ouverte la lumière d'échappement ; et une partie de pulvérisation (168) qui pulvérise un fluide ininflammable et qui est disposée sur la surface opposée (144c) faisant face à un piston disposé dans le cylindre.
(JA) このユニフロー掃気式2サイクルエンジンは、掃気ポートから流入した掃気によって、シリンダ内の排気ガスが排気ポート(142)から押し出されるユニフロー掃気式2サイクルエンジンであって、排気ポートを開放可能に閉塞する弁体(144a)と、弁体のうち、シリンダ内に配されたピストンに対向する対向面(144c)に設けられ、不燃性の流体を噴射する噴射部(168)と、を備える。
