  • Fuel injection - Wikipedia

    Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and rotary piston engines. All diesel (compression-ignition) engines use fuel injection, and many Otto (spark-ignition) enginesuse fuel injection of one kind or another. Mass-produced diesel engi

  • How Fuel Injection Systems Work | HowStuffWorks

    Inside a fuel injector When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle. The nozzle is designed to atomize the fuel -- to make as fine a mist as possible so that it can burn easily. A fuel injector firing
