  2. Solenoid (engineering) - Wikipedia

    en.wikipedia.org/wiki/Solenoid_(engineering)

    The rotary solenoid is an electromechanical device used to rotate a ratcheting mechanism when power is applied. These were used in the 1950s for rotary snap-switch automation in electromechanical controls. Repeated actuation of the rotary solenoid advances the snap-switch forward one position.

  3. Solenoid - Wikipedia

    en.wikipedia.org/wiki/Solenoid

    A finite solenoid is a solenoid with finite length. Continuous means that the solenoid is not formed by discrete coils but by a sheet of conductive material. We assume the current is uniformly distributed on the surface of the solenoid, with a surface current density K ; in cylindrical coordinates : K → = I l ϕ ^ . {\displaystyle {\vec {K ...

  4. Electronically controlled unit injector - Wikipedia

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

    The controlled part of the injector is a solenoid-operated spill valve. Normally, it is open, allowing the fuel to return to the supply line when the pump plunger descends. When the solenoid is energized, the spill valve closes, and the fuel is forced through the spray tip into the cylinder. The four phases of EUI operation are: Fill phase

  5. Solenoid valve - Wikipedia

    en.wikipedia.org/wiki/Solenoid_valve

    Solenoid valves. A solenoid valve is an electromechanically operated valve.. Solenoid valves differ in the characteristics of the electric current they use, the strength of the magnetic field they generate, the mechanism they use to regulate the fluid, and the type and characteristics of fluid they control.

  6. Reformed methanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Reformed_methanol_fuel_cell

    The fuel cartridge stores the methanol fuel. Depending on the system design either 100% methanol (IMPCA industrial standard) or a mixture of methanol with up to 40 vol% water is usually used as fuel for the RMFC system. 100% methanol results in lower fuel consumption than water-methanol mixture (Premix) but goes along with higher fuel cell system complexity for condensing of cathode moisture.

  7. Unit injector - Wikipedia

    en.wikipedia.org/wiki/Unit_injector

    The plunger is still on its way down, the engine ECU de-energizes the solenoid when the required quantity of fuel is delivered. The fuel valve opens, fuel can flow back into the return duct, causing the pressure to drop. Which in turn causes the injector nozzle needle to shut; hence no more fuel is injected. Summary

  8. Mitsubishi MCA - Wikipedia

    en.wikipedia.org/wiki/Mitsubishi_MCA

    [3] [4] Honda's CVCC Stratified charge engine approach also used a small third valve, but sent a richer air/fuel mixture to a small pre-combustion chamber near the spark plug, to help ignite a leaner air/fuel mixture in the main combustion chamber. MCA-Jet was a simpler system that sent the same air/fuel mixture to all intake and MCA-Jet valves.

    A solid oxide electrolyser cell (SOEC) is a solid oxide fuel cell set in regenerative mode for the electrolysis of water with a solid oxide, or ceramic, electrolyte to produce oxygen and hydrogen gas. Solid oxide fuel cell A solid oxide fuel cell (SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a ...
