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.

The environment load by traffic has reached limits of reasonableness in many places and metropoles. High mobility and environmental protection however can be equally fulfilled by consistently using latest automobile and engine technology. Nowadays the mean fuel consumption of new passenger cars equipped with gasoline engines is below 8 L/100 km and with diesel engines below 6 L/100 km. A 30 - 50 % reduction of fuel consumption within the next 10 years is expected with similar progress for commercial vehicle. This reduction of fuel consumption is not only important for saving resources, but also for protecting our global climate. The utmost target for engine development is to minimize both consumption and pollutant emissions. Effective reduction in classical pollutants for gasoline engines and new technologies such as oxydation Catalyst, De-NOx etc., for diesel engines have placed both power plants promising for passanger car market.
