Abstract

"MOTOR COM RAZãO DE COMPRESSãO VARIáVEL". Motor com uma razão de compressão variável inclui uma biela de conexão conectada a um pistão, um primeiro braço conectado giravelmente à biela de conexão e a um eixo de manivela através de um pino de manivela, um segundo braço conectado integralmente ao primeiro braço, uma haste de controle conectada giravelmente ao segundo braço e um eixo de suporte deslocável para sustentar a outra extremidade da haste de controle para movimento giratório. No motor, um deslocamento Vhpiv0 e uma razão de compressão <sym>piv0 no momento em que o eixo de suporte está em qualquer primeira posição e um deslocamento Vhpiv1 e uma razão de compressão; <sym>piv1 no momento em que o eixo de suporte está em uma segunda posição deslocada da primeira posição são determinados e uma relação, Vhpiv1 > Vhplv0, é satisfeita, quando <sym>piv1 < <sym>piv0, e uma relação, Vhplv1 < VhpivO, é satisfeita quando <sym>piv1 < <sym>piv0.
