caption_attribution_description: Jeep 2.5 Liter, four-cylinder engine, chromed. This picture of the display engine shows part of the fuel injection system (with MPFI). The fuel rail is connected to the injectors that are mounted just above the intake manifold. This engine was developed by American Motors Corporation (AMC) and continued to be manufactured by Chrysler. All were built in Kenosha, Wisconsin.
context_page_description: Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector.
  All compression-ignition engines use fuel injection, and many Spark-ignition engines use fuel injection of one kind or another. In automobile engines, fuel injection was first volume-produced in the late 1960s, and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies on suction created by intake air accelerated through a Venturi tube to draw the fuel into the airstream.
