問題詳情

IV. Reading: 18%     Aresearch team at National Central University (NCU) recentlyintroduced a prototype of a nearly pollution-free motorcycle poweredby compressed air, which they said could provide a solution to theproblem of pollution being emitted from over 14.2 million motorcycleson Taiwan’s streets.    Theteam, led by Hwang Yean-Ren, a professor of NCU’s Department ofMechanical Engineering, achieved a major breakthrough after two yearsof work on the project. The prototype, which burns no fuel and ispowered only by compressed air, has been dubbed the “NCU GreenEnergy No. 1 Air—powered Motorcycle.” Refitted from oldmotorcycle, the prototype is equipped with a steel cylindercontaining about 10 liters of compressed air that powers the enginefor a little over a kilometer at a maximum speed of 30kph.    Notingthat gasoline-powered motorcycles cause serious environmentalproblems, and that batteries used by electric motorcycles impose adifferent kind of pollution threat, Hwang said that the air-poweredbike could provide a total solution to environmental concerns.However, he admitted that it is still too early to talk about massproduction and price.    Theteam’s next steps will be to enhance the motorcycle’s efficiencyand reduce the noise produced by the air as it is emitted, he added.
