Abstract
An intake passage structure for an internal combustion engine includes a primary air-fuel mixture passage disposed remotely from a water jacket located below a secondary air-fuel mixture passage. A secondary slow fuel supply passage extends from a float chamber adjacent to the primary air-fuel mixture passage so that fuel in the secondary slow fuel supply passage will be cooled by an air-fuel mixture flowing through the primary air-fuel mixture passage, thereby preventing vapor lock from occuring in the secondary slow fuel supply passage. The primary air-fuel mixture passage is composed of a common passageway, a distribution slot and branch slots for supplying an air-fuel mixture to engine cylinders. The distribution and branch slots are closed by a cylinder head. Any liquid fuel in the distribution and branch slots are vaporized with heat from the cylinder head.
