V-twin-cylinder 16- and 18-hp engines have been named the best new product of the year made by a large company. The National Society of Professional Engineers, based in Alexandria, VA, gave its annual award to Kohler Co. (Kohler, WI). The firm built the air-cooled, four-stroke engines using an overhead camshaft (OHC) design. Incorporating an automotive-type belt and predominantly phenolic and powdered-metal components, the engines are three decibels quieter than comparable models throughout most of their operating range, the Society says. The award also cites Kohler for its innovative process of designing the OHC engines. The company made extensive use of solid modeling, rapid prototyping technology, customer input, and vendor participation. The tooling vendor made the tooling directly from the solid model, without the need to generate detailed prints.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
