...dollar than any tractor currently on the market, was shown by Ford Motor Co. Ford's "Typhoon" is powered by the same turbine-like free-piston engine (TIME, Nov. 14, 1955) already being tested in trucks and boats, has the advantage of low fuel cost, simpler construction (no crankshaft, no spark plugs), less vibration and no need for early-morning warmups. The company hopes to put a free-piston tractor on the market within the next few years...
This engine has many qualities that may endear it to Detroit and the motoring public. Like the gas turbine engine, it will run on the lowest grades of fuel, will even run on peanut oil. It needs no crankshaft or connecting rods, and it has so few rotating parts that friction and wear are far less than in standard piston engines. Furthermore, unlike the gas turbine, its turbine wheel runs cool, hence does not require costly heat-resistant alloys. General Motors has no immediate plans to produce the free-piston engine. But G.M.'s engineers hope that its debut...
...true gas turbine. It may well be a "free-piston engine," a combination of the piston engine and turbine. The idea of the engine is old, but only recently have automakers been able to eliminate many of the bugs. In the present engine, the pistons turn the crankshaft as the explosions in the cylinders drive them down, thus transfer power to the transmission and move the car. In the free-piston engine, there is no crankshaft. Instead, there are two pistons, at opposing ends of the cylinder, which force gas at tremendously high pressure into a turbine. The turbine...
Among the mechanized marvels: ¶A 70-ton monster built by Norton Co. of Worcester, Mass., which automatically moves a crankshaft from a grinding operation to drilling and milling and finally ejects it a job that had previously needed five machines. Saving in labor costs alone can estimated $38,000 a year on a two-shift operation...
...newest fast attack submarines, got under way from Belfast, Ireland and set a westward course for her home base at New London, Conn. One of Harder's engines was out of commission with a cracked block when the voyage began. About 650 miles west of Belfast, the crankshaft on a second engine broke. Sixteen hours later, Harder's last engine was partially disabled, and what little power it could generate had to be used to charge the submarine's ebbing batteries. Last week, 16 days after her departure from Belfast, Harder finally came into New London, trailing...
