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.
