    en.wikipedia.org/wiki/Power_over_Ethernet

    In a passive PoE system, the injector does not communicate with the powered device to negotiate its voltage or wattage requirements, but merely supplies power at all times. Common 100 Mbit/s passive applications use the pinout of 802.3af mode B (see § Pinouts ) – with DC positive on pins 4 and 5 and DC negative on 7 and 8 and data on 1–2 ...

  3. Electronically controlled unit injector - Wikipedia

    en.wikipedia.org/wiki/Electronically_controlled...

    An electronically controlled unit injector (EUI) sometimes referred to as a mechanical electronic unit injector (MEUI) is a unit injector (UI) with electronic control. It performs the same function as a conventional unit injector in an internal combustion engine , such as in an on-road or off-road vehicle or a diesel-electric locomotive .

  4. Bias tee - Wikipedia

    en.wikipedia.org/wiki/Bias_tee

    A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.

  5. Unit injector - Wikipedia

    en.wikipedia.org/wiki/Unit_injector

    A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and cooled by the fuel itself.

  6. Bendix-Stromberg pressure carburetor - Wikipedia

    en.wikipedia.org/wiki/Bendix-Stromberg_pressure...

    The floatless pressure carburetor was the progenitor of today's single-port fuel injection, and was a big step forward in fuel delivery technology. It could be looked upon as the mechanical counterpart of today's electronic fuel control system. These floatless pressure carburetors are the topic of this article. [2]

  7. Injector - Wikipedia

    en.wikipedia.org/wiki/Injector

    An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow.
