Variable nozzle turbine
Company: Honeywell Turbo Technologies
What: Better turbo boosts fuel economy 6 percent
Innovation: Honeywell made improvements to its main turbocharger for diesel engines. It improved wheel dynamics, for instance, and reduced friction in the bearings. Variable vanes on the nozzle can change shape and "focus" exhaust on the wheel so it still spins with low flow. The innovations boost an engine's fuel economy as much as 6 percent.
