Abstract: Disclosed is a fuel injection type carburetor of a multicylinder internal combustion engine. The carburetor comprises: an intake manifold comprising a plurality of horizontal intake passages; a throttle body connected to a converging portion of said intake manifold; a throttle valve installed within said throttle body; and a fuel injector arranged downstream from said throttle valve in a manner such that injected fuel can impinge against at least a part of said throttle valve. An opening direction of a valve portion of said throttle valve against which portion injected fuel impinges is substantially the same as the direction of fuel injection from said fuel injector.

Abstract: A fuel injection type carburetor of multi-cylinder internal combustion engines including: a throttle body having a throttle bore extending substantially vertically and being connected at the bottom portion thereof to a collecting portion of intake manifolds extending substantially horizontally; a throttle valve arranged in the throttle bore, and; a linear injection type fuel injection valve having a fuel injection nozzle arranged in the throttle bore in a downstream area of the throttle valve and inclined toward the downstream side. The throttle bore has an extension extending downwardly into the intake manifold collecting portion so that a fuel jet injected from the fuel injection nozzle strikes against the extension of the throttle bore.
