Fiat touts clean engine Chrysler could use

摘要

GENEVA - Italy's Fiat Group SpA unveiled a new engine at the Geneva Auto Show on March 4 that shows the kind of groundbreaking technology driving a proposed alliance with U.S. Chrysler LLC. The Multiair is a two-cylinder engine that Fiat claims is revolutionary in design, making it possible to reduce both fuel consumption and carbon emission up to 10 percent by controlling air flow during the combustion cycle, while downsizing from four to two cylinders saves weight as well.
