Germany's ten manufacturers showed off 30 basic models that come in 155 different versions, all with higher horsepower than before. Notable among them: Opel's completely restyled fastback Kadett, which borrows some of its lines from the Ford Mustang, and NSU's Spider, the only car in the world powered by the Wankel engine. Twelve companies in the U.S., Britain, France, Italy and Japan are now experimenting with the engine (which was developed in 1954 by Felix Wankel, a German engineer). The Wankel replaces conventional pistons and cylinders with a triangular rotor, has only two major...
Conventional gasoline engines have a basic fault; their reciprocating parts (pistons, connecting rods, etc.) must be stopped and started thousands of times per minute. This wastes power, and it also calls for a heavy engine to stand up against the battering it gets. Last week NSU Werke motor company of Neckar-sulm, West Germany described a gas engine that has neither pistons nor valves. Invented by a mechanical genius named Felix Wankel, it was developed with financial help from Curtiss-Wright Corp., which provided a fervid earlier announcement of it (TIME, Dec. 7) but no mechanical details...
Critical in the engine's design were the metal "piston rings" at the tips of the triangle that keep the chambers gastight. But NSU says the metal strips show no wear after 300 hours of fullspeed operation. The engine uses a conventional carburetor and can be made to burn many kinds of fuel, including diesel oil. It is not for sale yet, but NSU expects to have it debugged and in large production in about two years...
...diesel. It has no pistons or valves, only two moving parts; there is a carburetor to mix air and gasoline, a single spark plug, a rotor that drives the crankshaft. Beyond that. Hurley refused details. CW, he said, had developed the engine in conjunction with West Germany's NSU Werke, makers of autos and motorcycles, and had exclusive North American rights. In the works, said Hurley, was a whole string of models from...
...news brought only a statement from NSU that it was working on such an engine, which "still requires much research before it can become a commercial proposition." Privately, the Germans were furious; they claimed that the engine was their invention, that C-W had helped with development funds, and that any announcement at the moment was premature. But on Wall Street, where Curtiss-Wright stock has been hovering in the mid-30s for most of the year, the stock hopped 3¼ points to 35¼. Next morning C-W could not open for 35 minutes because...
