Abstract

Patente de Invenção:<B>"MOTOR DE COMBUSTãO INTERNA COM PISTãO LIVRE"<D>. Um motor de combustão interna com pistão livre tendo regulação melhorada de válvula. Um par de passagens de câmara de combustão opostamente dispostas (34, 36) estendendo-se entre a câmara de combustão (20) e a atmosfera da terra, cada uma tendo uma válvula da câmara de combustão (30, 32) para controlar a passagem de gás através das passagens (34, 36). As válvulas da câmara de combustão (30, 32) são essencialmente simultaneamente abertas e fechadas para permitir variação independente e controle da razão de compressão, razão de expansão e curso do motor. Quando as válvulas (30, 32) são abertas, a câmara de combustão (20) é purificada ou superalimentada com ar para a manutenção da combustão, e fechada para iniciar a compressão. O controle variável das posições do pistão (16, 18) nas quais as válvulas (30, 32) são abertas e fechadas permite que o motor opere em uma alta eficiência sobre uma ampla faixa de condições de carregamento de saída de potência.
