  3. Steam trap - Wikipedia

    en.wikipedia.org/wiki/Steam_trap

    Steam traps are nothing more than automatic valves. They open, close or modulate automatically. [1] The three important functions of steam traps are: Discharge condensate as soon as it is formed (unless it is desirable to use the sensible heat of the liquid condensate) Have a negligible steam consumption (i.e. be energy efficient)

  4. Locomotive wheelslip - Wikipedia

    en.wikipedia.org/wiki/Locomotive_wheelslip

    The greatest effort is required from a locomotive when starting. At this time, if the engineer applies too much power to the wheels (i.e., for a steam locomotive, the engineer opens the regulator too far) the turning force applied to the wheel will greatly exceed the opposing friction force affected by the surface of the rail, and the wheel will turn without being able to move the train forward.

  6. Variable valve timing - Wikipedia

    en.wikipedia.org/wiki/Variable_valve_timing

    Late intake valve closing (LIVC) The first variation of continuous variable valve timing involves holding the intake valve open slightly longer than a traditional engine. This results in the piston actually pushing air out of the cylinder and back into the intake manifold during the compression stroke.

  7. Valve timing - Wikipedia

    en.wikipedia.org/wiki/Valve_timing

    However, the duration of the intake event can be controlled (the "cut-off") using the reversing gear and this reduces steam usage under cruising conditions. Caprotti valve gear is more closely related to that of an internal combustion engine, uses poppet valves, and was developed to allow independent timing of the intake and exhaust events. It ...

  9. Governor (device) - Wikipedia

    en.wikipedia.org/wiki/Governor_(device)

    A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
