Abstract

"MOTOR DE CáRTER LIMPO, DE QUATRO CILINDRADAS". A presente invenção se refere a um motor de cárter limpo e lubrificado, de quatro cilindradas (1), compreendendo, especificamente: um dispositivo de preparação de mistura (15) para suprimento de uma mistura de ar-combustível-lubrificante; um canal de admissão (16), que se conecta ao cárter ou cilindro para suprir pelo menos ar (13) ao volume do cárter (12) ; um canal de transbordamento (17) que se conecta ao cárter ou cilindro e à abertura de admissão (7), com a válvula de admissão (8), para suprir ao dispositivo de admissão, pelo menos ar e lubrificante proveniente do volume do cárter; um conjunto de acionamento de válvulas (18), acionado por um virabrequim (4) para atuar a válvula de admissão (8) e a válvula de descarga (10); um alojamento do conjunto de acionamento de válvulas (19, 20, 21, 21', 22), compreendendo uma ou mais seções (19, 20, 21, 21', 22) que são separadas do cárter, mas, exclusivamente em comunicação com o volume de cárter através de pelo menos uma passagem de pequeno tamanho (23, 24, 25, 26, 27) e cada seção (19 , 20, 21, 21', 22) do alojamento do conjunto de acionamento de válvulas apresenta uma parte mais baixa, situada de modo mais alto na direção axial do furo do cilindro, isto é, mais próximo à câmara de combustão, do que a parte mais baixa do cárter.
