antiknock การใช้

• The antiknock index is an average of two separate octane tests.
• Octane ratings represent the antiknock properties of a gasoline or fuel mixture.
• Improvements to gasoline itself decrease the need for antiknock additives.
• This substance was commonly used as an antiknock agent in gasoline until 2005.
• Alkylate is a premium gasoline blending stock because it has exceptional antiknock properties and is clean burning.
• He also held patents on lacquers, antiknock fuels, pickling inhibitors, and laminated safety glass.
• Such PbCl 2 is emitted from internal combustion engines that use ethylene chloride-tetraethyllead additives for antiknock purposes.
• There, he worked with Thomas Midgley, Jr ., as part of Kettering's team researching antiknock agents.
• It had been established by 1921 that ethanol was an effective antiknock agent, but TEL was introduced instead mainly for commercial reasons.
• In 1921, a team of chemists performing research for General Motors discovered tetraethyllead ( TEL ) had antiknock properties as a gasoline additive.
• Ferrocene and its derivatives are antiknock agents added to the petrol used in motor vehicles, and are safer than the now-banned tetraethyllead.
• Prof . Nesmeyanov had also developed a number of industrial chemistry processes, including production of pharmaceuticals, antiknock agents, and artificial black caviar.
• A graduate of Transylvania College and Massachusetts Institute of Technology, Thomas worked as a research chemist at General Motors as part of a team researching antiknock agents.
• Triacetin can also be used as a fuel additive as an antiknock agent which can reduce engine knocking in gasoline, and to improve cold and viscosity properties of biodiesel.
• In 2007, it was reissued by Cold Spring with three bonus previously unreleased recordings from a 1990 show at Antiknock in Tokyo, and all songs as separate tracks.
• While gasoline is subjected to several other tests, the antiknock index _ a fuel's ability to resist engine knock, or ping _ is the measure of octane quality.
