    The digital fuel gauge in a 2018 Mazda 3 showing a nearly-empty tank along with a distance to empty display. Typical old-style fuel gauge on a 50 ccm chinese-made scooter from 2008, with the internationally used pictogram of a gas pump. The system can be fail-safe. If an electrical fault opens, the electrical circuit causes the indicator to ...

  4. Aircraft fuel system - Wikipedia

    en.wikipedia.org/wiki/Aircraft_fuel_system

    A single-engine piston aircraft has a simple fuel system; a tanker (such as the KC-135), in addition to managing its own fuel, can also provide fuel to other aircraft. [1] Fuel is piped through fuel lines to a fuel control valve (usually known as the fuel selector). This valve serves several functions.

  5. Indicator diagram - Wikipedia

    en.wikipedia.org/wiki/Indicator_diagram

    An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. [1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or ...

    en.wikipedia.org/.../Animated_Fuel_Injector

    An animated cut away diagram of a typical fuel injector. Fuel injectors are used to spray controlled amounts fuel into an internal combustion engine. A solenoid is activated when fuel is intended to be delivered to the engine causing the plunger to become pulled toward the solenoid by magnetic force. This uncovers the valve opening allowing ...

    OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

  9. McLeod gauge - Wikipedia

    en.wikipedia.org/wiki/McLeod_gauge

    A McLeod gauge is a scientific instrument used to measure very low pressures, down to 10 −6 Torr (0.133 mPa). It was invented in 1874 by Herbert McLeod (1841–1923). [ 1 ] McLeod gauges were once commonly found attached to equipment that operates under vacuum , such as a lyophilizer .
