Electronic fuel injection (EFI) replaced carburetors in the mid-1980s as the preferred method of supplying air and fuel to engines. The basic difference is that a carburetor uses intake vacuum and a pressure drop in the venturi (the narrow throat portion of the carburetor) to siphon fuel from the fuel tank of the carburetor in the engine, while the fuel injection Uses the pressure to spray fuel directly into the engine.
With an air of carburetor and fuel mix as air is drawn through the carburetor by the engine. The air / fuel mixture then travels through the intake manifold to the cylinders. One drawback of this approach is that the intake manifold is wet (contains liquid fuel droplets) so the fuel can form puddles in the plenum area of the manifold when a cold engine is started. The turns and turns of the intake guides can also cause the air-fuel mixture to separate as if it were flowing to the cylinders, resulting in uneven fuel mixtures between cylinders. The central cylinders typically operate slightly richer than the final cylinders, which makes optimizing fuel economy, performance and emissions more difficult with a carburetor.
