A hollow intake manifold-type body is provided for mounting between the cylinder banks of a V-type engine and the hollow body defines a vertically oriented inlet passage, a horizontally enlarged lower chamber into whose upper central portion the lower end of said intake passage opens, a horizontal baffle disposed in and dividing the lower chamber into upper and lower chamber sections communicated with each other in corresponding outer peripheral zones thereof spaced outwardly of the baffle, a vertically oriented outlet passage whose lower end opens downwardly through a central portion of the baffle and an upper chamber above the lower chamber and vertically through which the inlet passage extends. The outlet passage opens upwardly centrally into the upper chamber and the body additionally defines peripherally spaced intake runner passages opening outwardly of opposite sides of the body from the upper chamber at points spaced therealong for registry with the inlet ports formed in cylinder heads mounted on the cylinder banks. A filter screen is disposed across the communicating outer peripheral portions of the lower and upper chamber sections of the lower chamber and functions to break up any droplets of fuel attempting to pass therethrough. The air and fuel mixture is expanded and thus experiences a decrease in velocity during its movement through the fuel vaporizer and the droplets of fuel therein are broken up and thus afforded more time to completely vaporize.
