Direct Injection Internal Combustion Engines - The Automotive Industry's Contribution to Reduced CO2 Emissions

Direct Injection technology represents a major breakthrough for both, Gasoline and Diesel engines with respect to reduction of fuel consumption and thus CO2 emissions. However, for compliance with future European emission regulations Euro 3 and Euro 4 both engine types will require massive further development including advanced exhaust aftertreatment for lean NOx conversion. Actual development trends for both engine types are presented.
