Abstract

por exemplo, durante um período de tempo transitório de aceleração durante o qual uma carga de demanda é elevada, uma pressão de superalimentação é elevada antes de uma razão de compressão mecânica ser diminuída e um motor de combustão interna fica em um estado de carga alta. neste tempo, existe uma possibilidade de que uma geração de detonação e uma elevação excessiva em uma pressão interna de cilindro ocorram. esta possibilidade é uma questão a ser resolvida. o motor de combustão interna inclui: um mecanismo de razão de compressão variável que é capaz de modificar a razão de compressão mecânica; um turbocompressor (2) que superalimenta ar de admissão utilizando uma energia de escape; e uma válvula de desvio de escape (7) que ajusta uma pressão de superalimentação como um mecanismo de ajuste de pressão de superalimentação. a razão de compressão mecânica é detectada por um sensor de eixo de controle (34) e a pressão de superalimentação é limitada com base nesta razão de compressão mecânica.
