  • Air duct for engine
    Patent number: 8082906
    Abstract: An air duct 13 connected to the intake system of an engine 12 has a duct main body 13A and a cylindrical fuel adsorption filter 19 having air permeability. The fuel adsorption filter 19 is located in the duct main body 13A. The fuel adsorption filter 19 is arranged to be coaxial with respect to the duct main body 13A. A gap 21 is defined between the inner circumferential surface of the duct main body 13A and the outer circumferential surface of the fuel adsorption filter 19. An opening 22 for drawing air flow into the gap 21 is formed between an air flow upstream side of the gap 21 and an air passage area of the duct main body 13A.
