Abstract

"DETECTOR DE PRESSãO NEGATIVA DE AR DE ENTRADA PARA MOTOR DE COMBUSTãO INTERNA". Um motor de combustão interna (18) compreende um tubo de entrada (34) se estendendo de um corpo principal de motor de combustão interna (19) e tendo sua passagem de entrada interna (33) se comunicando com uma passagem de entrada (27) formada no corpo principal de motor de combustão interna (19), um dispositivo de alimentação de combustível (36) para alimentar combustível ao corpo principal de motor de combustão interna (19), um sensor de pressão negativa de ar de entrada (43) párea detectar a pressão negativa de ar de entrada (P) na passagem de entrada (33) do tubo de entrada (34), e um controlador (44) para controlar a taxa de alimentação de combustível alimentado no corpo principal de motor de combustão interna (19) pelo dispositivo de alimentação de combustível (36) na base do sinal de detecção do sensor de pressão negativa de ar de entrada (43). Está disposto que o sensor de pressão negativa de ar de entrada (43) detecta a pressão negativa de ar de entrada (P) na extremidade à jusante (42) da passagem de entrada (33) do tubo de entrada (34). De acordo com o sensor de pressão negativa de ar de entrada (43), o valor da pressão negativa de ar de entrada (P) na passagem de entrada (27) no corpo principal de motor de combustão interna (19) é detectado mais corretamente.
