Abstract

Patente de Invenção: <B>''FORMATO DE PORTA DE ADMISSãO PARA MOTOR DE COMBUSTãO INTERNA''<D>. Um objetivo da presente invenção é restringir uma parte do fluxo de admissão que é apto a fluir em uma direção oposta ao um fluxo de redemoinho contrário após colidir contra uma haste da válvula e para produzir um redemoinho intenso ao mesmo tempo que controlando uma piora do coeficiente do fluxo. Um assento da válvula suportando a superfície escalonada anular (14) é formado em uma parte de saída da porta de admissão de uma cabeça do cilindro (1), sua borda periférica interna é formada em um formato possuindo uma borda periférica interna (4a) de uma haste da válvula (4) para servir como um círculo base e uma parte que se estende (15) projetando-se em direção a um lado de uma haste da válvula (11) é proporcionado em um parte lateral da entrada da porta de admissão. A parte que se estende (15) é formada em um formato tipo montanha que aumenta a partir de uma parte de cima projetando-se em direção ao lado da haste da válvula para ambos lados periféricos e conecta-se com o círculo base em suas extremidades do sopé; ou em um formato tipo arco; ou em um formato trapezoidal. Uma parede traseira (16) é formada em um lado oposto ao assento da válvula da parte que se estende (15), a parede traseira diminuindo sua altura de projeção em direção a um lado a montante da porta de admissão para suavemente conectar-se com uma superfície interna da parede periférica da porta de admissão 2.
