Abstract
sistema de cilindro de trabalho para um motor alternativo a presente invenção refere - se, em geral, a motores alternativos e, mais particularmente, a um conjunto de pistão para um motor alternativo. o sistema (8) de cilindro de trabalho para um motor alternativo (10), compreende um pistão (20, 174) configurado para ser disposto dentro de um cilindro (26) e para mover-se de uma maneira alternativa dentro do cilindro (26); um sulco de topo (42) que se estende de modo circunferencial sobre o pistão (20, 174) abaixo de uma superfície de topo (40, 172) do pistão (20, 174); um anel (44) disposto dentro do sulco de topo (42); e um canal único (100) formado na superfície de topo (40, 172) ou no anel (44), em que o canal único (100) se estende de um perímetro exterior (80) do pistão (20, 174) para um espaço (130) entre uma superfície interna (131) do sulco de topo (42) e uma face interna (124) do anel (44); o canal único (100) é posicionado em uma região de temperatura baixa do pistão (20, 174) em relação a outras regiões de temperatura mais alta do pistão (20, 174).
