Abstract

"APARELHO DE CONTROLE DE VáLVULAS PARA MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a um aparelho de controle de válvulas para um motor de combustão interna, que é apresentado para capacitar de maneira ideal o tempo de fechamento de uma válvula de motor de acordo com as condições operacionais do motor enquanto suprimindo um aumento na massa inercial da válvula de motor para o mínimo, desse modo obtendo aperfeiçoamento da economia de combustível, e realização de maior velocidade de rotação do motor e rendimento de potência mais elevado em uma maneira compatível, e reduzindo seus custos e peso. O aparelho de controle de válvulas controla as operações de abertura e fechamento de uma válvula do motor. Um mecanismo de acionamento de válvula do tipo excêntrico aciona a válvula do motor para abrir e fechar a válvula do motor, por um excêntrico que é acionado em sincronismo com a rotação do motor. Um atuador efetua o engate de bloqueio com a válvula de motor tendo sido aberta, para dessa maneira reter a válvula de motor em um estado aberto. Uma unidade ECU controla operação do atuador para desse modo controlar o tempo de fechamento da válvula de motor.
