Research: Emissions control in the global light vehicles industry
Date published: Tuesday, June 16, 2009
Description
The technologies that enable emissions control and reductions in light vehicles are manifold and include several exhaust after-treatment systems that are increasingly being integrated, new combustion control approaches, hybrid and other powertrain systems, and a range of fuel-efficiency technologies that reduce the use of petroleum-derived fuels. Added to this, the increasing use of alternative fuels holds the promise of further reductions of toxic emissions.
This report examines the technologies that are being developed in the area of emissions control in the global light vehicles industry. It also analyses the strategies being implemented by passenger car manufacturers and their suppliers and the market and legislative influences that are driving change in the sector.
