  2. Wobbe index - Wikipedia

    en.wikipedia.org/wiki/Wobbe_index

    The Wobbe index is expressed in MJ/Nm³ (where 'Nm³' indicates'm³ in Normal conditions), or sometimes in BTU/scf.In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 39 MJ/Nm³ (1,050 BTU/scf) and the specific gravity is approximately 0.59, giving a typical Wobbe index of 51 MJ/Nm³ (1,367 BTU/scf).

  3. Liquefied petroleum gas - Wikipedia

    en.wikipedia.org/wiki/Liquefied_petroleum_gas

    LPG cylinders in India Liquefied petroleum gas tank on a rural farm. Predominantly in Europe and rural parts of many countries, LPG can provide an alternative to electric heating, heating oil, or kerosene. LPG is most often used in areas that do not have direct access to piped natural gas. In the UK about 200,000 households use LPG for heating.

  4. API gravity - Wikipedia

    en.wikipedia.org/wiki/API_gravity

    Hydrometers in the U.S. had been manufactured and distributed widely with a modulus of 141.5 instead of the Baumé scale modulus of 140. The scale was so firmly established that, by 1921, the remedy implemented by the American Petroleum Institute was to create the API gravity scale, recognizing the scale that was actually being used.

  6. Gasoline - Wikipedia

    en.wikipedia.org/wiki/Gasoline

    A high-octane-rated fuel, such as liquefied petroleum gas (LPG), has an overall lower power output at the typical 10:1 compression ratio of an engine design optimized for gasoline fuel. An engine tuned for LPG fuel via higher compression ratios (typically 12:1) improves the power output.

  7. Liquid fuel - Wikipedia

    en.wikipedia.org/wiki/Liquid_fuel

    Petroleum fuels, when burnt, release carbon dioxide that is necessary for plant growth, but which (given the large scale of global emissions) is potentially harmful to world climate. The amount of carbon dioxide released when one liter of fuel is combusted can be estimated: [1] As a good approximation the chemical formula of e.g. diesel is C n ...

  8. Filling carousel - Wikipedia

    en.wikipedia.org/wiki/Filling_carousel

    A filling carousel is intended for filling large quantities of liquefied petroleum gas (LPG) cylinders. It consists of a frame with running wheels, rails, a central column for LPG and air, and a driving unit the carousel frame around the central column. The speed of the carousel can be adapted to the various filling times and capacities.

  9. Autogas - Wikipedia

    en.wikipedia.org/wiki/Autogas

    Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane. [1] Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared to petrol. [2]
