  2. Orbit insertion - Wikipedia

    en.wikipedia.org/wiki/Orbit_insertion

    An orbit insertion maneuver involves either deceleration from a speed in excess of the respective body's escape velocity, or acceleration to it from a lower speed. When the result is a transfer orbit, e.g. a descent orbit insertion, the maneuver is an orbit injection.

  3. Current injection technique - Wikipedia

    en.wikipedia.org/wiki/Current_injection_technique

    In summary, current injection technique makes it possible to use devices with low forward voltage drop for high frequency applications. This also imply cheaper cost of devices as less processing steps are required during the manufacturing stages where the need of carrier lifetime control techniques are reduced.

  4. Mercedes-Benz M110 engine - Wikipedia

    en.wikipedia.org/wiki/Mercedes-Benz_M110_engine

    The M110.981 uses Bosch D-Jetronic injection. This system senses the ambient temperature, engine temperature, intake manifold underpressure and throttle valve position and calculates with an analog computer how many milliseconds the fuel injectors should stay open per revolution. The .991 is the low-compression version of the .981.

  5. Low-speed pre-ignition - Wikipedia

    en.wikipedia.org/wiki/Low-Speed_Pre-Ignition

    Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI), [1] is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. [2] LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions. [3]

  6. Ion implantation - Wikipedia

    en.wikipedia.org/wiki/Ion_implantation

    Ion implantation setup with mass separator. Ion implantation equipment typically consists of an ion source, where ions of the desired element are produced, an accelerator, where the ions are electrostatically accelerated to a high energy or using radiofrequency, and a target chamber, where the ions impinge on a target, which is the material to be implanted.

  7. Electronically controlled unit injector - Wikipedia

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

    Injection phase Partway through the pump stroke, the solenoid is energized, which closes the spill valve. The fuel is forced into the cylinder through the spray tip. Pressure reduction phase Toward the end of the pump stroke, the spill valve is re-opened, allowing the fuel to recirculate again and ending the injection phase.

  8. Restrictor plate - Wikipedia

    en.wikipedia.org/wiki/Restrictor_plate

    Artist rendering of a NASCAR restrictor plate. A restrictor plate or air restrictor is a device installed at the intake of an engine to limit its power. This kind of system is occasionally used in road vehicles (e.g., motorcycles) for insurance purposes, but mainly in automobile racing, to limit top speed to provide equal level of competition, and to lower costs; insurance purposes have also ...

  9. DC injection braking - Wikipedia

    en.wikipedia.org/wiki/DC_injection_braking

    A DC injection brake system can be used as an alternative or addition to a friction brake system. DC injection brakes only require a small module located with the other motor switchgear and/or drivers, mounted in a remote and convenient location, whereas a friction brake must be mounted somewhere on the rotating system.
