...other big manufacturer of piston engines, Curtiss-Wright Corp., is making a hybrid (for the Navy) on a different plan. Its Turbo-Cyclone 18 is a regular, 18-cylinder piston engine whose exhaust drives three turbines geared directly to the crankshaft. The energy recovered gives the engine more horsepower with over 15% more fuel economy...
...into Pittsburgh's Federal Court, demanded from Carnegie-Illinois Steel Corp. & the National Tube Co. a whopping $120 million. Last week in Cleveland, the same union sued Republic Steel for $56 million, American Steel & Wire Co. for $38 million. The United Automobile Workers demanded $12 million from Ohio Crankshaft...
...item which Jahco thinks has turned the trick is a two-cylinder, 30-h.p., air-cooled engine for light cars. Designed by Vice President Ralph Heintz, the cylinders, cylinder head and crankshaft are die-cast from aluminum alloy. The engine weighs 175 pounds less than similar engines, yet produces the same power. Jahco expects to make four-and six-cylinder models for planes and boats...
...Maintaining industrial equipment. One massive 9½-ft., 2,400-lb. Diesel crankshaft was worn at its bearing points. Wartime replacement was impossible; in any case, would have taken twelve weeks. A hot-metal sprayer, using 45 lb. of steel wire, resurfaced the worn shaft in ten hours...
Knocking is caused by premature explosion of gasoline vapors before the piston has returned to the cylinder head. These out-of-rhythm explosions can ruin a motor, perhaps break its crankshaft. High octane materials-octane, lead, alkylates-prevent these premature explosions by slowing down the rate of explosion. Though all gasoline explosions are a matter of split seconds, some are "slow," others "fast." Each kind of hydrocarbon in gasoline ignites at a slightly different temperature and compression. Igniting slowly and in order, they give the piston a firm, continued push instead of a brief, wrenching, power-wasting punch. So high...
