I.Прочитайте текст и выполните следующие за ним задания: Smart carburetor. «Умный» карбюратор. 1.It’s a bold company that spends nearly eight years improving a product that may not be around 20 years from now. But that’s what the Vacuum Carburetor Corp. of San Antonio, Texas, has done. The firm has developed a new vacuum-controlled constant-velocity carburetor, better known as the Econo Carb, which its maker says offers several advantages over ordinary carburetors – including 25 per can’t better gasoline mileage, improved engine performance and easier starting. The device which has only 54 parts compared with some 300 in regular carburetors, has no choke or accelerator pump – and therefore cannot flood. The device constantly adjusts the mix of fuel and air in the manifold, which regular carburetors with fixed mixes cannot do. “When your engine demands fuel, it will give it just enough to do the job,” says Frank Greene, president of Vacuum Carburetor. “It’s the same concept as a cruise control.” 2.The vacuum carburetor is not a new idea – some of the earliest carburetors (in the 1920s and 1930s) were vacuum-type. Al Woodworth, Californian, invented a modern vacuum carburetor several years ago; what Vacuum Carburetor has done is modify Woodworth’s creation, mainly by adding a fuel-injection “cold-start” mechanism that, the company claims, helps the engine turn over immediately in frigid weather. 3.Though the Econo Carb has been on sale for less than a year, it’s already being used by municipal car, truck and cab fleets in Nashville, Denver and San Antonio. What’s more, Saudi Arabia, China and Denmark are interested in importing the device. William Moreton, an executive at Vacuum Carburetor’s production plant in Kansas, says the Econo carb’s natural market is as a replacement for existing carburetors, especially in V-6 and V-8 engines.
