Abstract
resumo patente de invenção: "relação de compressão variável motor a diesel". a presente invenção refere-se a motores a diesel de pistões opostos, opcionalmente com uma relação de compressão variável e/ou turbo compressor, que pode proporcionar aprimorada eficiência de combustível por adaptar a relação de compressão do motor de acordo com a carga do motor de modo que maiores relações de compressão são usadas para menores cargas e menores relações de compressão são usadas para maiores cargas. turbo compressor pode proporcionar aprimorada eficiência em condições de operação de relação de compressão menor. opcionalmente, um ou mais parâmetros atuais do motor podem ser modificados para manter a temperatura de pico da câmara de combustão abaixo da temperatura limiar na qual um nível aceitável de poluentes de óxido de nitrogênio (nox) é esperado ser formado. uma ou mais características de indução de redemoinho podem ser incluídas nas coroas de pistão em um motor de pistões opostos. métodos, sistemas, artigos de fabricação, etc. são descritos. 23482346v1 1/1 23482346v1
