  2. Fuel pump - Wikipedia

    en.wikipedia.org/wiki/Fuel_pump

    By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel; Liquid fuel by itself (i.e. without oxygen present) isn't flammable, therefore surrounding the fuel pump by fuel reduces the risk of fire; In-tank fuel pumps are often part of an assembly consisting of the fuel pump, fuel strainer and fuel ...

    en.wikipedia.org/wiki/Vapor_lock

    Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.

  4. Active Fuel Management - Wikipedia

    en.wikipedia.org/wiki/Active_Fuel_Management

    It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.

  5. Fuel control unit - Wikipedia

    en.wikipedia.org/wiki/Fuel_control_unit

    A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve. The operator has a power lever which only controls the engine's potential, not the actual fuel flow. The fuel control unit acts as a computer to determine the amount of fuel needed to deliver the power requested ...

  8. Dieseling - Wikipedia

    en.wikipedia.org/wiki/Dieseling

    The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is ...
