  2. Deglazing (engine mechanics) - Wikipedia

    en.wikipedia.org/wiki/Deglazing_(engine_mechanics)

    If the cylinder walls are too smooth, this wear will not occur, with the rings "skating" over the polished surface. [1] In order to correct the situation, a mechanic can take the engine apart, and deglaze the cylinders, usually using an abrasive.

  3. Siamesed cylinders - Wikipedia

    en.wikipedia.org/wiki/Siamesed_cylinders

    Siamesed cylinders are engine cylinders arranged in such a way that they have no channels between them to allow water or other coolant to circulate. [ 1 ] [ 2 ] Cylinders are generally arranged in this manner when the engine block is of limited size or when stability of the cylinder bores is of concern, such as in racing engines. [ 3 ]

  4. Bore (engine) - Wikipedia

    en.wikipedia.org/wiki/Bore_(engine)

    Engine displacement is calculated based on bore, stroke length and the number of cylinders: [1] displacement = π ( ⁠ 1 / 2 ⁠ × bore ) 2 × stroke × n cylinders. The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds or torque at lower engine ...

    Larger examples were built as multiple rows. As each row contains an odd number of cylinders, to give an even firing sequence for a four-stroke engine, an even number indicates a two- or four-row engine. The largest of these was the Lycoming R-7755 with 36 cylinders (four rows of nine cylinders), but it did not enter production.

  6. Cylinder (engine) - Wikipedia

    en.wikipedia.org/wiki/Cylinder_(engine)

    Cylinder liners (also known as sleeves) are thin metal cylinder-shaped parts which are inserted into the engine block to form the inner wall of the cylinder. [4] [5] Alternatively, an engine can be 'sleeveless', where the cylinder walls are formed by the engine block with a wear-resistant coating, such as Nikasil or plasma-sprayed bores.

  7. Indicator diagram - Wikipedia

    en.wikipedia.org/wiki/Indicator_diagram

    An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. [1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or ...

  8. Deglazing - Wikipedia

    en.wikipedia.org/wiki/Deglazing

    Deglazing refers to the removal of a shiny or smooth surface. Deglazing (cooking) , using a liquid to remove cooked-on residue from a pan Deglazing (engine mechanics) , abrading the polished surface of a cylinder

  9. Subaru EJ engine - Wikipedia

    Note: Cylinder head and camcase must be replaced together (line bored). the sparkplug pipe is pressed into the cylinder head and is not serviceable. If it becomes damaged the cylinder head must be replaced. The seals installed onto the ends of the sparkplug pipes seal against the valve covers and should be replaced when the valve cover is removed.
