  2. Ceramic engine - Wikipedia

    en.wikipedia.org/wiki/Ceramic_engine

    A ceramic engine is an internal combustion engine made from specially engineered ceramic materials. Ceramic engines allow for the compression and expansion of gases at extremely high temperatures without loss of heat or engine damage. [1] Proof-of-concept ceramic engines were popularized by successful studies in the early 1980s and 1990s.

  3. Component parts of internal combustion engines - Wikipedia

    en.wikipedia.org/wiki/Component_parts_of...

    A piston is a component of reciprocating engines. It is located in a cylinder and is made gas-tight by piston rings. Its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In two-stroke engines the piston also acts as a valve by covering and uncovering ports in the cylinder ...

    They are generally diesel engines with combustion chamber parts lined with ceramic thermal barrier coatings. [13] Some make use of titanium pistons and other titanium parts due to its low thermal conductivity [14] and mass. Some designs are able to eliminate the use of a cooling system and associated parasitic losses altogether. [15]

    They are generally piston engines with combustion chamber parts lined with ceramic thermal barrier coatings. [247] Some make use of pistons and other parts made of titanium which has a low thermal conductivity [248] and density. Some designs are able to eliminate the use of a cooling system and associated parasitic losses altogether. [249]

  7. Cylinder (engine) - Wikipedia

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

    The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, [1] which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder ...

    Coatings used in modern motorcycles include chromium, [13] nitride, [14] or ceramic coating made by plasma deposition [15] or physical vapour deposition (PVD). [ 16 ] [ 17 ] Most modern diesel engines have top rings coated with a modified chromium coating (known as CKS or GDC), [ 13 ] [ dead link ‍ ] which has aluminium oxide or diamond ...

  9. Nikasil - Wikipedia

    en.wikipedia.org/wiki/Nikasil

    This coating allowed aluminum cylinders and pistons to work directly against each other with low wear and friction. Unlike other methods, including cast iron cylinder liners, Nikasil allowed very large cylinder bores with tight tolerances. This made it possible for existing engine designs to be expanded easily.
