  2. Separator (oil production) - Wikipedia

    en.wikipedia.org/wiki/Separator_(oil_production)

    A means of controlling an oil level in the separator, which usually includes a liquid-level controller and a diaphragm motor valve on the oil outlet. A back pressure valve on the gas outlet to maintain a steady pressure in the vessel. Pressure relief devices.

  3. Oil pump (internal combustion engine) - Wikipedia

    en.wikipedia.org/wiki/Oil_pump_(internal...

    The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings and also assists in cooling the engine.

  4. Reverse-flow cylinder head - Wikipedia

    en.wikipedia.org/wiki/Reverse-flow_cylinder_head

    However, the advent of fuel injection and electronic ignition has made most of the reverse-flow head's advantages redundant in a modern engine and as a result the design has lost its popularity. The reverse-flow head still enjoys some popularity among enthusiasts including Leyland Mini, Chrysler Slant-6, Holden and Ford Inline 6 fans.

  5. Dry sump - Wikipedia

    en.wikipedia.org/wiki/Dry_sump

    The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump. A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted.

  6. Reverse flow - Wikipedia

    en.wikipedia.org/wiki/Reverse_flow

    Reverse flow may refer to: In engine technology a reverse flow cylinder head is one that locates the intake and exhaust ports on the same side of the engine. Reverse logistics, i.e. goods/waste flowing in the distribution network having consumers as point of origin; Reverse electron flow is a mechanism in microbial metabolism

  7. Crossflow cylinder head - Wikipedia

    en.wikipedia.org/wiki/Crossflow_cylinder_head

    A crossflow head gives better performance than a Reverse-flow cylinder head (though not as good as a uniflow), but the popular explanation put forward for this — that the gases do not have to change direction and hence are moved into and out of the cylinder more efficiently — is a simplification since there is no continuous flow because of valve opening and closing.

  8. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    [4] [5] [6] A generalized model of the flow distribution in channel networks of planar fuel cells. [6] Similar to Ohm's law, the pressure drop is assumed to be proportional to the flow rates. The relationship of pressure drop, flow rate and flow resistance is described as Q 2 = ∆P/R. f = 64/Re for laminar flow where Re is the Reynolds number.

  9. Flow coefficient - Wikipedia

    en.wikipedia.org/wiki/Flow_coefficient

    With C v = 1.0 and 200 psia inlet pressure, the flow is 100 standard cubic feet per minute (scfm). The flow is proportional to the absolute inlet pressure, so the flow in scfm would equal the C v flow coefficient if the inlet pressure were reduced to 2 psia and the outlet were connected to a vacuum with less than 1 psi absolute pressure (1.0 ...
