  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 ...

    Definition of the part via a 3D CAD model rather than via a 2D engineering drawing. Drawings may be printed (plotted) from the model for reference use, but the model remains the governing legal instrument. MBP: measurement between pins: threads, splines, gears (internal, female) (synonymous with MBW) (see also MOP, MOW) MBW: measurement between ...

    The rocker arms for the intake valve were widened on the valve end to accommodate the cartridge, which was equipped with a very soft valve spring in order to avoid wear on the camshaft intake lobe. Modifications to the head were thereby reduced as the Jet Valve negated the necessity for a three-valve-per-cylinder design.

    P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational ...

    Using the PRV method of control, means that the pressure of the feed oil must be below a critical value (usually controlled by other valves which can leak out excess oil back to tank if it exceeds the critical value). The valve opens at a certain pressure and oil is kept moving at a constant rate into the bearing chamber.

    Engineering drawing – a type of technical drawing that is used to convey information about an object. Detail drawings commonly specify the dimensions and tolerances for the construction of a single component, while a master drawing or assembly drawing links the detail drawings for each component in a system. Only required information is ...
