Nitrous Oxide Engine
A nitrous oxide engine, or nitrous oxide system (NOS) is an internal combustion engine in which oxygen for burning the fuel comes from the decomposition of nitrous oxide, N2O, as well as air. The system increases the engine's power output by allowing fuel to be burned at a higher-than-normal rate, because of the higher partial pressure of oxygen injected with the fuel mixture. Nitrous injection systems may be "dry", where the nitrous oxide is injected separately from fuel, or "wet" in which additional fuel is carried into the engine along with the nitrous. NOS may not be permitted for street or highway use, depending on local regulations. N2O use is permitted in certain classes of auto racing. Reliable operation of an engine with nitrous injection requires careful attention to the strength of engine components and to the accuracy of the mixing systems, otherwise destructive detonations or exceeding engineered component maximums may occur. Nitrous oxide systems were applied a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plenum Chamber
A plenum chamber is a pressurised housing containing a fluid (typically air) at positive pressure. One of its functions is to equalise pressure for more even distribution, compensating for irregular supply or demand. It is typically relatively large in volume and thus has relatively low velocity compared to the system's other components. In wind tunnels, rockets, and many flow applications, it is a chamber upstream on the fluid flow where the fluid initially resides (approximately at rest). It can also work as an acoustic silencer. Examples Examples of plenum chambers include those used with: * Superchargers * Hovercraft * Corliss steam engines * Raised floors and false ceilings in equipment rooms * Some organ (music), organs (to supplement the bellows) * A number of aerophones, such as the bag of bagpipes and the ''slow air chamber'' of the Native American flute * Anaesthetic vaporiser#Plenum vaporisers, Plenum chamber anesthetic vaporizers * Rocket engine#Combustion chamber, R ...

Natural Gas Vehicle
A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas (LPG), NGVs rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source. Conversion of existing gasoline or diesel vehicles to NGVs is feasible, offering both dedicated and bi-fuel options. Heavy-duty vehicles such as trucks and buses can also undergo conversion, utilizing spark ignition systems or hybrid electric motor configurations. Challenges in NGV adoption include the storage and refueling of natural gas, given its pressurized or liquefied state. While advancements in compression and liquefaction mitigate energy density differences, trade-offs regarding storage container size, complexity, and weight continue to affect vehicle range. Despite these challenges, the safety and cost advantages of methane over hyd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TÜV
TÜVs (; short for , ) are internationally active, independent service companies from Germany and Austria that test, inspect and certify technical systems, facilities and objects of all kinds in order to minimize hazards and prevent damages. The TÜV companies are organized into three large holding companies, TÜV Nord, TÜV Rheinland and TÜV SÜD (with TÜV Hessen), along with the smaller independent companies TÜV Thüringen, TÜV Saarland and TÜV Austria. History With the increasing number and efficiency of steam engines during the Industrial Revolution, there had been more and more accidents caused by exploding (or more precisely, bursting) boilers. After the explosion of the boiler at the Mannheim Aktienbrauerei in January 1865, the idea was pursued there to subject boilers to regular inspections on a voluntary basis, as was already the case in Great Britain. Twenty boiler owners in Baden joined in the plans and finally founded the ''Gesellschaft zur Überwachung und Ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roads & Traffic Authority
The Roads & Traffic Authority (RTA) was an Statutory authority, agency of the Government of New South Wales responsible for major road infrastructure, licensing of drivers, and registration of motor vehicles. The RTA directly managed state roads and provided funding to Local government in Australia, local councils for regional and local roads. In addition, with assistance from the federal government, the RTA also managed the NSW national highway system. The agency was abolished in 2011 and replaced by Roads & Maritime Services. History The Department of Main Roads (New South Wales), Department of Main Roads (DMR) was established in November 1932, and undertook works across New South Wales, including maintenance of all major roads into Sydney and programs of road reconstruction, construction, upgrading and rerouting. The DMR was also responsible for many ferries and bridges in New South Wales. On 16 January 1989, the Department of Main Roads, Department of Motor Transport, ...

New South Wales
New South Wales (commonly abbreviated as NSW) is a States and territories of Australia, state on the Eastern states of Australia, east coast of :Australia. It borders Queensland to the north, Victoria (state), Victoria to the south, and South Australia to the west. Its coast borders the Coral Sea, Coral and Tasman Seas to the east. The Australian Capital Territory and Jervis Bay Territory are Enclave and exclave, enclaves within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. , the population of New South Wales was over 8.3 million, making it Australia's most populous state. Almost two-thirds of the state's population, 5.3 million, live in the Greater Sydney area. The Colony of New South Wales was founded as a British penal colony in 1788. It originally comprised more than half of the Australian mainland with its Western Australia border, western boundary set at 129th meridian east in 1825. The colony then also includ ...

Torque Converter
A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the prime mover to the automatic gear train, which then drives the load. It is thus usually located between the engine's flexplate and the transmission. The equivalent device in a manual transmission is the mechanical clutch. A torque converter serves to increase transmitted torque when the output rotational speed is low. In the fluid coupling embodiment, it uses a fluid, driven by the vanes of an input impeller, and directed through the vanes of a fixed stator, to drive an output turbine in such a manner that torque on the output is increased when the output shaft is rotating more slowly than the input shaft, thus providing the equivalent of an adaptive reduction gear. This is a feature beyond what a simple fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Transmission
An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors ''Hydramatic'' two-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are especially prevalent in vehicular drivetrains, particularly those subject to intense mechanical acceleration and frequent idle/transient operating conditions; commonly commercial/passenger/utility vehicles, such as buses and waste collection vehicles. Prevalence Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive t ...

Aerosolization
Aerosolization is the process or act of converting some physical substance into the form of particles small and light enough to be carried on the air i.e. into an aerosol. Aerosolization refers to a process of intentionally oxidatively converting and suspending particles or a composition in a moving stream of air for the purpose of delivering the oxidized particles or composition to a particular location. Aerosolization is also an important concept of air pollution whereby particulate matter is formed and evaded into the atmosphere. Gas-phase substances reach the atmosphere by volatilization, whereas solid and liquid-phase particles can reach the atmosphere by aerosolization. This is a mechanism by which semivolatile organic compounds (SVOCs) like halogenated and organphosphate pesticides become air pollutants . The term is often used in medicine to refer specifically to the production of airborne particles (e.g. tiny liquid droplets) containing infectious virus or bacteria. The i ...
