Although the liquid nitrogen is colder than the ambient temperature, the liquid nitrogen engine is nevertheless an example of a heat engine.A heat engine runs by extracting thermal energy from the temperature difference between a hot and a cold reservoir; in the case of the liquid nitrogen engine, the "hot" reservoir is the air in the ambient ("room temperature") surroundings, which is used to ...
Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...
Both liquid air and liquid nitrogen have been used experimentally to power cars. A liquid air powered car called Liquid Air was built between 1899 and 1902 but it couldn't at the time compete in terms of efficiency with other engines. [21] More recently, a liquid nitrogen vehicle was built.
Liquid nitrogen Liquefaction of gases is physical conversion of a gas into a liquid state ( condensation ). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders .

A supply of liquid oxygen is carried to support burning of diesel fuel to power the engine. Stirling engines are also fitted to Swedish Södermanland-class submarines, the Archer-class submarines in service in Singapore, and the Japanese Sōryū-class submarines, with the engines license-built by Kawasaki Heavy Industries. In a submarine ...
On May 25, 1902, and after two years of research, Georges Claude developed a process for liquefying air in order to separate the components (oxygen, nitrogen, argon). On November 8, 1902, Paul Delorme gathered twenty-four subscribers, mainly engineers, to financially support the project, [5] and became the first president of "Air liquide, a company for the study and exploitation of Georges ...
Liquid rocket engines have tankage and pipes to store and transfer propellant, an injector system and one or more combustion chambers with associated nozzles.. Typical liquid propellants have densities roughly similar to water, approximately 0.7 to 1.4 g/cm 3 (0.025 to 0.051 lb/cu in).
