...leading to the carburetor, it draws in fuel and air. Then the cavity decreases in volume, compressing the mixture. The engine's single spark plug fires; the exploding gas pushes the rotor and shaft. At the end of the power stroke, a corner of the rotor uncovers the exhaust port, and the burned gases are swept out of the engine. Meanwhile, two other cavities have been formed and are passing through the same cycle. Maximum shaft speed is 17,000 r.p.m., but the rotor turns over only one-third as fast...
Smog Reliever. The automobile industry will use an inexpensive device to control smog-producing automobile fumes in all cars manufactured for sale in California in 1961. The industry has discovered that hot gases from the exhaust pipe are not the main source of air pollution; smog is mainly caused by the oily vapors, principally hydrocarbons, that gather in the crankcase, are normally vented into the open air. The new device is a tube from the crankcase vent to the intake manifold. This carries the hydrocarbons through the engine, where they are burned up. Price: about...
...Snow Train. The New York Central Railroad developed a snow blower that harnesses the exhaust of a B-36 jet bomber engine to blast its freight-yard tracks and switches free of snow. Mounted on a modified caboose with a huge nozzle, the engine can blow away snow...
