...pistons successively suck in a mixture of gasoline and air, compress it, turn a crankshaft after an electric spark touches off the explosive vapors, then expel the burned fuel residues. In rotary engines like the Wankel, the same effect is achieved not by reciprocating pistons but by a turning rotor. As it revolves inside a specially shaped chamber, the rotor is able to perform all the basic strokes of a piston engine: induction, compression, ignition and exhaust. The new engine, originally conceived by Karol to get more performance out of motorcycles, combines what he considers the best of both systems...
...Reporters from the Wall Street Journal had a defective rotor installed in an otherwise perfect car and took the car to several Dallas auto repair shops. The one mechanic who fixed only the rotor charged $1. Six others made unnecessary repairs, one charging $54.60 for his services. Two other mechanics wanted the car left for even more expensive repairs, and one suggested a $130 valve...
...engine, and in high-level conversations around them, knowing mentions are made of something called an epitrochoid. Visitors soon learn that the models are see-through likenesses of the Wankel rotary engine-and an epitrochoid, in case they did not know, is the bloated figure-eight shape that its rotor follows when moving. Both the baubles and the vocabulary are just two more signs that the long-discussed Wankel has finally shifted up from being Detroit's vague "engine of the future" to a much more imminent status. The auto industry's growing number of Wankel watchers, including...
Coattails. The Wankel revolution has been expected for years, chiefly because of the rotary engine's elegant simplicity. Instead of converting up-and-down piston motion into wheel-driving circular energy through a series of complex linkages-the way a standard engine works-the Wankel rotors spin continuously and thus provide the proper torque to move a car's wheels directly. Rotary engines are smaller, peppier and potentially cheaper to build than conventional reciprocating models, and have only six major points of wear, v. 100 in a conventional engine. The most persistent bug, ever since Inventor Felix Wankel...
...land in elephant grass in a clearing. The only thing to be heard besides the rotor blades is the feeble stutter of the door gunner's machine gun. The landing zone is "cold" -meaning that there are no enemy about-but the troops find fresh tracks almost immediately. We follow the trail until shortly after 5. when another night position is set up. The forward artillery observer calls in artillery strikes on an area that he thinks the enemy might have moved into. He orders the strikes for 10 p.m. -like booking a telephone call-and waits...
