Exhaust Systems
An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of: *Cylinder head and exhaust manifold *A turbocharger to increase engine power. *A catalytic converter to reduce air pollution. *A muffler (North America) / silencer (UK/India), to reduce noise. Design criteria An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with poisonous exhaust gases such as hydrocarbons, carbon monoxide and nitrogen oxides, if they are not properly vented to the outdoors. Also, the gases from most types of machines are very hot; the pipe must be heat-resistant, and it must not pass through or near anything that can burn or can ...

Thermal Barrier Coatings
Thermal barrier coatings (TBCs) are advanced materials systems usually applied to metallic surfaces operating at elevated temperatures, such as gas turbine or aero-engine parts, as a form of exhaust heat management. These 100 μm to 2 mm thick coatings of thermally insulating materials serve to insulate components from large and prolonged heat loads and can sustain an appreciable temperature difference between the load-bearing alloys and the coating surface. In doing so, these coatings can allow for higher operating temperatures while limiting the thermal exposure of structural components, extending part life by reducing oxidation and thermal fatigue. In conjunction with active film cooling, TBCs permit working fluid temperatures higher than the melting point of the metal airfoil in some turbine applications. Due to increasing demand for more efficient engines running at higher temperatures with better durability/lifetime and thinner coatings to reduce parasitic mass fo ...

Limited Company
In a limited company, the liability of members or subscribers of the company is limited to what they have invested or guaranteed to the company. Limited companies may be limited by Share (finance), shares or by guarantee. In a company limited by shares, the liability of members is limited to the unpaid value of shares. In a company limited by guarantee, the liability of owners is limited to such amount as the owners may undertake to contribute to the assets of the company, in the event of being wound up. The former may be further divided in public companies (public limited company, public limited companies) and private companies (private limited company, private limited companies). Who may become a member of a private limited company is restricted by law and by the company's rules. In contrast, anyone may buy shares in a public limited company. Limited companies can be found in most countries, although the detailed rules governing them vary widely. It is also common for a distinct ...

Carbon-fiber-reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addit ...

Wear
Wear is the damaging, gradual removal or deformation of material at solid surfaces. Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion). The study of wear and related processes is referred to as tribology. Wear in machine elements, together with other processes such as fatigue and creep, causes functional surfaces to degrade, eventually leading to material failure or loss of functionality. Thus, wear has large economic relevance as first outlined in the Jost Report. Abrasive wear alone has been estimated to cost 1-4% of the gross national product of industrialized nations. Wear of metals occurs by plastic displacement of surface and near-surface material and by detachment of particles that form wear debris. The particle size may vary from millimeters to nanometers. This process may occur by contact with other metals, nonmetallic solids, flowing liquids, solid particles or liquid droplets entrained in flowing gasses. The wear rate is affected by f ...

Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c). Definition T ...

Coloured Ceramic Thermal Barrier Coating On Exhaust Component
Coloureds ( af, Kleurlinge or , ) refers to members of multiracial ethnic communities in Southern Africa who may have ancestry from more than one of the various populations inhabiting the region, including African, European, and Asian. South Africa's Coloured people are regarded as having some of the most diverse genetic background. Because of the vast combination of genetics, different families and individuals within a family may have a variety of different physical features. ''Coloured'' was a legally defined racial classification during apartheid referring to anyone not white or not a member of one the aboriginal groups of Africa on a cultural basis, which effectively largely meant those people of colour not speaking any indigenous languages. In the Western Cape, a distinctive Cape Coloured and affiliated Cape Malay culture developed. In other parts of Southern Africa, people classified as Coloured were usually the descendants of individuals from two distinct ethnicities ...

Management Buyout
A management buyout (MBO) is a form of acquisition in which a company's existing managers acquire a large part, or all, of the company, whether from a parent company or individual. Management-, and/or leveraged buyout became noted phenomena of 1980s business economics. These so-called MBOs originated in the US, spreading first to the UK and then throughout the rest of Europe. The venture capital industry has played a crucial role in the development of buyouts in Europe, especially in smaller deals in the UK, the Netherlands, and France. Overview Management buyouts are similar in all major legal aspects to any other acquisition of a company. The particular nature of the MBO lies in the position of the buyers as managers of the company and the practical consequences that follow from that. In particular, the due diligence process is likely to be limited as the buyers already have full knowledge of the company available to them. The seller is also unlikely to give any but the most ...

Fibre-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. Process definition A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers, the result is referred to as a plastic. Composite plastics refers to those types of plastic ...

Koenigsegg
Koenigsegg Automotive AB () is a Swedish manufacturer of high-performance sports cars based in Ängelholm, Skåne County, Sweden. Company The company was founded in 1994 in Sweden by Christian von Koenigsegg, with the intention of producing a "world-class" sports car. Many years of development and testing led to the CC8S, the company's first street-legal production car which was introduced in 2002. In 2006, Koenigsegg began production of the CCX, which uses an engine created in-house specifically for the car. The goal was to develop a car homologated for use worldwide, particularly the United States whose strict regulations did not allow the import of earlier Koenigsegg models. In March 2009, the CCXR was listed by ''Forbes'' as one of "the world's most beautiful cars". In December 2010, the Agera won the BBC Top Gear Hypercar of the Year Award.
