  • semiconductors.In the first category are substances which provide an easy path for an electric current. All metals are conductors, however some metals do not conduct well. Manganin, for example, is a poor conductor. Copper is a good conductor, therefore it is widely used for cables. A non-metal which conducts well is carbon. Salt water is an example of a liquid conductor. A material which does not easily release electrons is called an insulator. Rubber, nylon, porcelain and air are all insulator. There are no perfect insulators.

  • History At the beginning of the automotive century, around 1900– 1910, battery electric vehicles (BEVs), cars with steam engines, and cars with gasoline engines coexisted. They were competing with respect to power, comfort, and maintenance. As described by R. H. Schallenberg, it took the electric starter and the starting, lighting, and ignition (SLI) system (created by Charles Kettering on the demand from Henry Leyland for the 1911 Cadillac Model Thirty) to improve the comfort in use of the gasoline engine vehicle sufficiently to outperform others. ...

  • The Mk. II Volkswagen Golf and Jetta range of models was introduced in March 1984, revised body and trim features being the main visual difference to the earlier range of models. The engine/transmission is mounted transversely at the front of the vehicle, drive being to the front wheels. Detailed improvements have been made throughout the years of manufacture to improve power output and economy.

  • 57.1.5 Gas Turbine Operation Like other internal combustion engines, the gas turbine requires an outside source of starting power. This is provided by an electrical motor or diesel engine connected through a gear box to the shaft of the gas turbine (the high-pressure shaft in a multishaft configuration). Other devices can be used, including the generator of large electric utility gas turbines, by using a variable frequency power supply.

  • Technological improvements might also involve the adoption and use of alternative fuel or alternative propulsion vehicles. In developing countries, the most commonly discussed alternative vehicle strategies include compressed natural gas (CNG), liquefied petroleum gas (LPG), alcohol-based fuels, and electric propulsion or hybrid -electric vehicles in certain applications. Other alternative fuels showing potential long -term promise in the transport sector include hydrogen fuel cells and various synthetic fuels for use in compression-ignition engines.
