  2. Break-in (mechanical run-in) - Wikipedia

    en.wikipedia.org/wiki/Break-in_(mechanical_run-in)

    Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...

  3. Technical Service Bulletin - Wikipedia

    en.wikipedia.org/wiki/Technical_Service_Bulletin

    Technical Service Bulletins (TSBs) are document recommended procedures for repairing vehicles issued by a vehicle manufacturer when there are several occurrences of an unanticipated problem. [1] TSBs can range from vehicle-specific to covering entire product lines and break down the specified repair into a step-by-step process.

  4. Exhaust manifold - Wikipedia

    en.wikipedia.org/wiki/Exhaust_manifold

    Crossplane V8 engines have a left and right bank each containing 4 cylinders. When the engine is running, pistons are firing according to the engine firing order. If a bank has two consecutive piston firings it will create a high pressure area in the exhaust pipe, because two exhaust pulses are moving through it close in time.

  5. 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.

  6. Thermal barrier coating - Wikipedia

    en.wikipedia.org/wiki/Thermal_barrier_coating

    This is possible because the ceramic material bonds with the composite (instead of merely sticking on the surface with paint), thereby forming a tough coating that doesn't chip or flake easily. Although thermal barrier coatings have been applied to the insides of exhaust system components, problems have been encountered because of the ...

  7. Conservation and restoration of ceramic objects - Wikipedia

    en.wikipedia.org/wiki/Conservation_and...

    There are several ways in which ceramics break down physically and chemically. Additionally, the type of ceramic will affect how it will break down. Unfired clay, like mud and clay adobe, is clay that is fired under 1000°C or 1832°F. [contradictory] This type of clay is water-soluble and unstable. Earthenware is clay that has been fired ...

  8. Ceramic matrix composite - Wikipedia

    en.wikipedia.org/wiki/Ceramic_matrix_composite

    Fracture surface of a fiber-reinforced ceramic composed of SiC fibers and SiC matrix. The fiber pull-out mechanism shown is the key to CMC properties. CMC shaft sleeves. In materials science ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix.

  9. Shop-replaceable unit - Wikipedia

    en.wikipedia.org/wiki/Shop-Replaceable_Unit

    Repair at backshops is known as field-level maintenance or intermediate-level (I-level) maintenance. SRUs are similar in nature to line-replaceable units (LRUs), but rather than being complete functional units, represent component functions, such as circuit card assemblies, of a larger LRU.
