  2. Cylinder Head Temperature gauge - Wikipedia

    en.wikipedia.org/wiki/Cylinder_Head_Temperature...

    A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air-cooled engines, the head temperature gauge displays the work that the engine is performing more quickly than an oil or water temperature gauge. As the engine works at high speed or uphill, head temperature will increase quickly.

  4. SAE J300 - Wikipedia

    en.wikipedia.org/wiki/SAE_J300

    SAE J300. SAE J300 is a standard that defines the viscometric properties of mono- and multigrade engine oils, maintained by SAE International. [1] Key parameters for engine oil viscometrics are the oil's kinematic viscosity, its high temperature-high shear viscosity measured by the tapered bearing simulator, and low temperature properties ...

    A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system used to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.). Found on the instrument panel of most ...

  7. Mini-rotary viscometer - Wikipedia

    en.wikipedia.org/wiki/Mini-rotary_viscometer

    The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures. [1][2] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades. The requirement was added after the winters of 1980-81 and 1981-82 caused major ...
