Combustion, английский
- Сгорание; горение
- Горение, сожжение
- Any chemical process that produces light and heat as either glow or flames.
- Burning, &c. (see spontaneous combustion.)
- Сгорание, сжигание, горение, возгорание
- Сгорание. химическая реакция, при: которой вещество соединяется с кислородом с выделением тепла: «горение». сгорание топлива, содержащего углерод и водород, считается полным, если цроисходит полное окисление этих двух элементов до углекислого газа и воды. неполное сгорание может привести к тому, что: 1) в золе остается значительное количество углерода; 2) часть углерода выделяется в виде окиси углерода; и 3) молекулы топлива реагируют с образованием ряда продуктов более сложного состава по сравнению с исходными молекулами топлива, и если эти продукты не сгорают, они выделяются в виде дыма. сгорание летучих продуктов может протекать более полно, если сверху на слой топлива подается так называемый вторичный воздух (воздух, пропускаемый через слой топлива, называется «первичным»). воздух сверх количества, теоретически необходимого для полного сгорания (избыточный воздух), следует подавать с минимальным избытком, чтобы` избежать неоправданных потерь тепла с дымовыми газами, слабой теплопередачи и окисления двуокиси серы в трехокись. перенасыщенное сгорание происходит в системе, где топливо подается сверху на раскаленный слой топлива. такая система характеризуется тенденцией к образованию дыма. тороидальное (кольцевое) сгорание происходит в системе, где в печи поддерживается вихревой поток; это увеличивает время пребывания топлива в печи и настолько улучшает горение, что дополнительной подачи воздуха, требуется мало или не требуется совсем. 40
- A combustion reaction involves a substance combining with an oxidizer, releasing a large amount of heat (exothermic) and produces a flame. the heat produced can make combustion self-sustaining. an oxidizer is a compound that takes electrons in a reaction and can promote or initiate combustion. oxygen and chlorine are examples of oxidizers. when oxygen is available in sufficient amounts, complete combustion occurs. if a hydrocarbon undergoes complete combustion, carbon dioxide and water vapor are produced. combustion reactions can be oxygen starved or can involve excess oxygen. in an oxygen starved combustion reaction, a combustion reaction has a limited oxygen supply and incomplete combustion occurs. in an environment of combustion in excess air, the amount of oxygen supplied to the combustion reaction is more than is needed for complete combustion and can lead to a hotter, faster burning fire.
- A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.

Compressor, английский
- Compresseur;surpresseur
- A mechanical device that pressurizes a gas in order to turn it into a liquid, thereby allowing heat to be removed or added. a compressor is the main component of conventional heat pumps and air conditioners. in an air conditioning system, the compressor n
- Part of a split-system heat pump or air conditioner’s outdoor unit that controls the pressure applied to the refrigerant so that it can circulate. it plays a vital role in taking in heat to warm your home with a heat pump or getting rid of heat to keep yo
- In an air conditioner this is known as
- The compressor plays an integral role in cooling your home. it is the device responsible for pumping refrigerant through the refrigerant lines and the coil, making the transfer of heat from inside your house to the outdoors possible. rheem uses high-quali
- A device which converts mechanical force and motion into pneumatic fluid power.
- Компрессор
- A machine for compressing air or other gases which is a basic component in some refrigeration systems; draws vaporized refrigerant from the evaporator at a relatively low pressure, compresses it, and then discharges it to a condenser. compressor-type liquid chiller equipment utilizing a compressor, condensor, evaporator, controls, and accessories to cool water or other secondary liquid. compression coupling compression faucet
- A mechanism generally adopted afloat for facilitating the working of the large guns recently introduced; the gun-carriage is thus compressed to its slide or platform during the recoil, and set free again by the turn of a handle for running up. it is of various forms; one of the simpler kind used to be always applied to carronade slides.
- Система сжатия данных; компрессор
- A signal processor that reduces dynamic range by using automatic volume control. also, an amplifier whose gain decreases as the input signal level increases above a pre-set point.
- An air pump, usually electrically driven, which supplies air under pressure (generally between 90 and 140 psi) for use on trains. brakes, doors and other items of equipment like suspension and whistles commonly require compressed air. compressors may be driven directly off a diesel engine or from an electrical supply on the locomotive or train. see the brakes page for more details.
- An engine that is used to increase natural gas pressure so that it can more easily flow through the pipeline.

Commercial vehicle, английский
Vehicle used for the transportation of goods, materials, or for gain or reward other than in the conveyance of passengers, and registered or licensed as such. exact definition will be liable to local variation and interpretation. see also articulated vehicle
Cold sticking, английский
Sticking of piston ring in groove when engine is cold. the ring will normally become free when the engine is warm. see also hot sticking. column change gear
