Abstract

"MéTODO DE PARTIDA PARA MOTOR DE COMBUSTãO INTERNA E DISPOSITIVO DE PARTIDA PARA O MESMO". A presente invenção visa facilitar o pistão a superar o primeiro ponto morto superior de compressão após a parada da operação de descompressão sem superdimensionar um motor elétrico para o acionamento. Desta forma, é previsto em um motor de combustão interna equipado com um mecanismo de descompressão, um came de descompressão que é girável em relação a um eixo de cames (16) dentro do ângulo Ad entre as primeira e segunda posições de parada tem um tal perfil de came que uma válvula de descarga é aberta na primeira posição de parada, que e é fechada na segunda posição de parada. O came de descompressão é girado na direção inversa até a primeira posição de parada girando o eixo de manivelas na direção inversa pelo motor elétrico na partida (posição P1), e então somente o eixo de manivelas é girado na direção inversa (posição P3), e então o came de descompressão é girado na direção normal girando o eixo de manivelas na direção normal pelo motor elétrico. Durante ou o curso de compressão (S8) incluído dentro da faixa do ângulo de rotação inversa Ar ou o primeiro curso de compressão (S12) após o início da rotação normal do came de descompressão durante o período de tempo até que o came de descompressão atinja a segunda posição de parada, o came de descompressão abre a válvula de descarga e aumenta o ângulo de subida Aa do eixo de manivelas.
