Honeywell expects its second-generation gasoline turbochargers to be on the road within three years. The world's largest turbochargers maker says that its new so-called "Gasoline DualBoost" is 30 percent lighter, 30 percent smaller and achieves up to 70 percent less inertia compared with current similar turbos.
"This allows us to downsize engines even further," Honeywell Turbo Technologies Vice President of Engineering Craig Balis told Automotive News Europe.
He said that reducing inertia helps speed the acceleration rate of the turbo so that boost pressure can be built up more rapidly. The end result is a turbo that is more responsive and more efficient, improving performance and fuel efficiency, Balis said.
Automakers in Europe need to reduce CO2 ahead of tougher emissions regulations that start to take effect next year.
Roland Berger expects that demand for turbos in light vehicles will double to 30.4 million in 2015 from an estimated 18.2 million in 2011 and rise to 16.9 million units in Europe by mid-decade from an estimated 11.2 million this year.
Honeywell, whose closest competitor is BorgWarner, controls half of the global turbocharger market based on analysts estimates. The supplier, however, faces increasing competition – especially in Europe. Continental AG's first turbocharger will be produced by the Schaeffler Group starting later this year. A joint venture between Robert Bosch GmbH and Mahle GmbH also will start turbocharger output this year.
Honeywell expects to introduce more than 100 new turbo applications this year and has more than 500 engine applications in its development pipeline.
