Spreading Flame. With that addition, the cycle of the stratified-charge engine remains quite similar to the sequence in ordinary internal combustion engines: 1) As the piston descends, a rich fuel mix from one carburetor is injected into the small combustion chamber near the spark plug. A leaner mixture, from a second carburetor, is squirted into the rest of the cylinder. 2) Moving up, the piston compresses both charges, pushing back most of the richer mix that may have seeped into the main chamber. 3) The spark plug fires the rich mix. 4) The rich, burning mix ignites the adjoining...
Ginger is no old bag. She maintains her excellent figure with exercise and ensures a degree of mental stimulation with such ticklish malapropisms as "He's quite a piston," "defoliating" virgins, and (referring to bisexuals) "AM-FM." When Dolly divorces Smackenfelt for Zap Spontini, an advertising man and lousy Sunday painter, Blodgett is rewarded. Smackenfelt marries his aunt-in-law and settles down to an excellent relationship, sexually and otherwise. Ginger pays the bills, leaving the unemployed actor time to sharpen his theatrical skills...
...nearly two more years, or until Detroit is ready with its own rotary engine, Mazda will be the only car sold in the U.S. with the rotary: a power system, first designed by West Germany's Felix Wankel, that is half the size of the conventional piston engine and has only three moving parts, v. 166 in a piston engine with comparable horsepower. In the best tradition of U.S. monopolists, the Japanese-owned car maker is making all the hay it can while the sun is shining. Last week the company expanded to two big, new sections...
Richard Ansdale, a British rotary-engine specialist who is close to completing a working prototype of the engine, considers this division of labor by the pistons-or "split cycling," as he calls it-a distinctive feature. By relieving the power piston of the job of inducting air, it allows the engine to take in more air and burn its fuel during a much greater portion of each cycle than in conventional engines. Moreover, a blast of fresh air helps expel the exhaust gases before any more fuel is introduced. The net result, Ansdale explains, is not only a more efficient...
...almost vibration-free and weighs much less than conventional engines with equivalent horsepower. Ansdale figures that a 145-h.p. model would be only 27 in. long and 18 in. wide. Finally, the design has a distinction that the Wankel cannot claim: because of the uncomplicated shape of its pistons and rotor, it can be built with familiar piston-engine techniques. In contrast, the Wankel has introduced many new engineering problems...
