Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
Drawing the retorts at the Great Gas Establishment Brick Lane, from The Monthly Magazine (1821). The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century.
The fuel for these early engines was a relatively volatile hydrocarbon obtained from coal gas. With a boiling point near 85 °C (185 °F) (n-octane boils at 125.62 °C (258.12 °F) [1]), it was well-suited for early carburetors (evaporators). The development of a "spray nozzle" carburetor enabled the use of less volatile fuels.
The earliest known gas wells were drilled in China in AD 347 or earlier. They had depths of up to about 800 feet (240 m) and were drilled using bits attached to bamboo poles. [10] [11] [12] The gas was burned to evaporate brine and produce salt. By the tenth century, extensive bamboo pipelines connected gas wells with salt springs. The ancient ...
The fuel-characteristics of a particular gasoline-blend, which will resist igniting too early are measured as the octane rating of the fuel blend. Gasoline blends with stable octane ratings are produced in several fuel-grades for various types of motors. A low octane rated fuel may cause engine knocking and reduced efficiency in reciprocating ...
This engine was fuelled by gas vapours, used the piston's intake stroke to draw in outside air, and the air/fuel mixture was ignited by an external flame. [6] Another gas engine was also patented in 1794 by Thomas Mead. [7] 1801: The concept of using compression in a two-stroke gas engine was theorised by French engineer Philippe LeBon D ...
Josef Papp (c. 1933 – April 1989) was an American engineer who was awarded U.S. patents related to the development of an engine, and also claimed to have invented a jet submarine. He was born in Tatabánya, Hungary and died in Daytona Beach, Florida. Papp was issued several U.S. patents for these inventions, including his noble gas fuel ...
Fuel gas is widely used by industrial, commercial and domestic users. Industry uses fuel gas for heating furnaces, kilns, boilers and ovens and for space heating and drying . The electricity industry uses fuel gas to power gas turbines to generate electricity. The specification of fuel gas for gas turbines may be quite stringent. [5]
