Direct-injection, internal-combustion engines - the automotive industry's contribution to reduced CO_2-emissions

摘要

Direct-injection technology represents a major breakthrough for both gasoline and diesel engines with respect to reduction of fuel consumption and thus CO_2-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 NO_x conversion. Actual development trends for both engine types are presented.
