Patent number: 11371477Abstract: An engine cover covers an engine; and an intake pipe through which the air is introduced into the engine. An intake silencer is provided adjacent to the intake pipe and suppresses air pressure fluctuations of air in the intake pipe to reduce intake sound. A portion of the intake silencer is covered with the engine cover, and a remaining portion is exposed with respect to the engine cover. An advantage is that secondary noise generated by the intake silencer and a temperature increase of air suctioned into the engine are simultaneously suppressed.Type: GrantFiled: July 17, 2020Date of Patent: June 28, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Yuta Takamura, Motohiro Ariki, Masakazu Kikuchi, Chizuki Nakamura
