  2. Mitsubishi MCA - Wikipedia

    en.wikipedia.org/wiki/Mitsubishi_MCA

    MCA-Jet was a simpler system that sent the same air/fuel mixture to all intake and MCA-Jet valves. Each MCA-Jet valve is quite small and may be prone to carbon build-up, causing the MCA-Jet valve(s) to stick open. If a Mitsubishi-designed engine has low compression, the MCA-Jet valve(s) could be the cause. Each MCA-Jet valve and valve seat are ...

  5. Mitsubishi Vulcan engine - Wikipedia

    en.wikipedia.org/wiki/Mitsubishi_Vulcan_engine

    "MCA" stood for "Mitsubishi Clean Air", reflecting Japan's new air quality laws. The MCA-II was cleaner yet, and with balance shafts it also offered a much smoother run, at the loss of a few horsepower. The Sports engine did not meet the stricter emissions laws, which led to the demise of the Skipper.

    Electrical shocks on humans can lead to permanent disabilities or death. Size, frequency and duration of the electrical current affect the damage. [8] The effects from electric shock can be: stopping the heart beating properly, preventing the person from breathing, causing muscle spasms. The skin features also affect the consequences of ...

  8. Environmental control system - Wikipedia

    en.wikipedia.org/wiki/Environmental_control_system

    A manifold pressure regulating shut-off valve (MPRSOV) restricts the flow as necessary to maintain the desired pressure for downstream systems. A certain minimum supply pressure is needed to drive the air through the system, but it is desired to use as low a supply pressure as possible, because the energy the engine uses to compress the bleed ...
