(EN) FOUR-STROKE INTERNAL COMBUSTION ENGINE AND EXHAUST VALVE
(FR) MOTEUR À COMBUSTION INTERNE À QUATRE TEMPS ET SOUPAPE D'ÉCHAPPEMENT
(JA) 4ストローク内燃機関と排気弁
要約
(EN)
Disclosed is a four-stroke internal combustion engine which is provided with: a cylinder part (1) in which a recess (depression) (14) formed by setting back an internal wall in such a way that no choke is produced with a side edge (26) of a valve head (22) of an exhaust valve (2) is provided at the upper edge of the internal wall; and the exhaust valve (2) in which the cross-sectional shape of a top part (23) of the valve head (22) is formed to become narrower from an outer peripheral edge (25) of the valve head (22) towards the top.
(FR)
Moteur à combustion interne à quatre temps comportant : une partie cylindre (1) qui présente elle-même dans la partie supérieure de sa paroi intérieure un renfoncement (14) tel qu'il n' y a pas de rétrécissement au niveau du bord latéral (26) de la tête (22) de la soupape d'échappement (2) ; et une soupape d'échappement (2) dont la forme en coupe de la partie (23) de la tête (22) va en rétrécissant depuis un bord périphérique (25) de la tête de soupape (22) vers le haut.
(JA)
 排気弁2の弁傘22の側縁26との間にチョークが発生しないように内壁を後退させて形成したリセス(凹み)14を内壁の上縁部に設けたシリンダ部1と、弁傘22の頭部26の断面が弁傘22の外周縁25より頭頂に近づくにつれて細くなる形状に形成された排気弁2を備える。
