Abstract

um anel de barreira para um conjunto de cilindro para um motor de êmbolos opostos é ajustado dentro de um sulco praticado em uma porção da camisa de cilindro que é adjacente ao local do ponto morto superior das superfícies de extremidade dos êmbolos, em um volume da camisa do cilindro que define a câmara de combustão. o anel de barreira e o sulco fazem parte de um conjunto de barreira que impede que o calor gerado durante a combustão atinja a parede externa do conjunto de cilindro, reduzindo a necessidade de sistemas de resfriamento convencionais e aumentando a quantidade de calor retido na câmara de combustão. o conjunto de barreira permite uma maior eficiência do motor, devido ao calor de combustão retido na câmara de combustão, assim como uma redução das dimensões totais do motor devido à redução do resfriamento de motor necessário.
