Abstract

"MOTOR DE COMBUSTãO INTERNA DE DOIS TEMPOS". A presente invenção se refere a um motor de combustão interna de cárter ou de caixa de manivela de limpeza (1) (scavenged = eliminação ou remoção de gases queimados a partir do cilindro de um motor de combustão interna após um tempo de estágio) do tipo de dois tempos, compreendendo um cilindro (2) com um tubo de admissão (10) para mistura de ar/combustível e um número de dutos de transferência (20), um carburador (12) conectado para o tubo de admissão (10), e uma admissão de ar (24) proporcionada com uma válvula de restrição (25), por meio do que um canal de pistão de passagem de ar (23, 22, 26, 21) está disposto entre a admissão de ar (24) e a parte superior dos dutos de transferência (20). A admissão de ar (24) do motor se estende pelo menos parcialmente abaixo e exterior ao carburador (12), resultando em um projeto de motor mais compacto e aperfeiçoada utilização do espaço em torno do cilindro. Além do mais, a refrigeração de ar dá melhor acesso para o cilindro.
