Abstract

Objeto: Proporcionar una técnica para contribuir al equilibrio de la mejora de la eficiencia de la combustión y la reducción de peso. Medios de resolución: Una sección (35) rebajada, provista en el espacio entre un segundo pasaje (322) de admisión y un tercer pasaje (323) de admisión de los espacios entre cada pasaje (32) de admisión, se forma en una pared (27b) inferior de una parte (27) de montaje a fin de abrir hacia la dirección en que está mirando una plataforma (24) inferior, no hacia la dirección en que está mirando una placa (27a) de contacto. Esto permite que no se limite el tamaño de la sección (35) rebajada, incluso en el caso en que un miembro (58) de cojinete se dispone en el espacio entre el segundo pasaje (322) de admisión y el tercer pasaje (323) de admisión para soportar de manera giratoria un eje (54) de válvula debido a la provisión de un dispositivo (50) de válvula de control de volteo en una parte (46) de reborde de montaje de un colector (4) de admisión. Esto permite que se logre un equilibrio de la mejora de la eficiencia de la combustión y la reducción de peso de un motor de combustión interna (1).
