Abstract

resumo “motor de combustão interna com razão de compressão variável” a presente invenção é equipada com um mecanismo com razão de com-pressão variável (10) que altera uma razão de compressão de mecanismo-motor dependendo da posição rotacional de um primeiro eixo de controle (14), e um atua-dor que altera e mantém a posição rotacional do primeiro eixo de controle (14). um mecanismo de ligação que liga o atuador e o primeiro eixo de controle (14) tem uma alavanca (24) ligada ao primeiro eixo de controle (14). a ponta de uma parte de bra-ço (25) que se estende radialmente para fora a partir do centro do primeiro eixo de controle (14) e uma extremidade da alavanca (24) são ligadas de modo girável por um primeiro pino de conexão (26). pelo menos, quando foi definida a razão de com-pressão mais alta, o primeiro pino de conexão (26) é submerso abaixo de um nível de óleo (?1) do recipiente de óleo (6).
