  • Patent number: 7757479
    Abstract: A secondary air supply system in which individual members may be arranged to be disposed on substantially the same straight line in an engine, whereby connection path lengths are reduced and the attachment thereof is facilitated. The secondary air supply system may be provided between an air cleaner and attached to an engine and an exhaust port of the engine. The secondary air supply system has a secondary air control valve, a lead valve and secondary air supply paths which connect the air cleaner, the secondary air control valve and the lead valve together and supply air to the exhaust port from the air cleaner. The air cleaner, the secondary air control valve and the lead valve may be arranged to be disposed on substantially the same straight line when viewed from the side.
