/ 15 2006 Gasoline versus Diesel – Can New Generation Gasoline Engines Halt the Advance of the Diesel? The duel between gasoline and diesel engine was on the agenda of the “Engine & Environment” conference in September 2006. Rita Forst (General Motors Powertrain Europe) described General Motors’ “March to Zero” in her keynote address. According to Forst, an essential requirement of sustainable mobility is the right balance between customer and market demands, legal provisions and economic efficiency. Dr. Leopold Mikulic (DaimlerChrysler AG) detected significant potential for fuel consumption reduction through direct injection in the gasoline engine in his keynote speech on “Gasoline engines versus diesel engines – The future of conventional powertrains”. He also presented the DIESOTTO as a possible “future combination of gasoline and diesel engine”. The objective of developing the “cleanest diesel engine in the world” could be reached with in-engine measures, diesel particulate filter and BlueTec exhaust gas treatment. Dr.-Ing. Dirk Andriesse of Fiat Powertrain Technologies (with Dr. Franco Cazzolato, Dr. Aldo Marangoni, Dr. Aldo Oreggioni and Dr. Stefano Quinto) identified a “serious competition for the direct injection diesel engine” in the new generation of highly efficient gasoline direct injection engines that could challenge the current (note: 2006) hegemony of the diesel engine in some vehicle categories. Fritz Steinparzer‘s (BMW Motoren GmbH) presentation was entitled “Diesel engines for passenger cars: past – present – future” and described the various optimization efforts of BMW. His conclusion: “Despite the already very advanced state of development, there is still great potential for functionality improvement in all relevant fields of engineering. An encouraging approach is also being pursued with regard to the key issue of NOx emissions. Other efforts, too, such as gradual “electrification” and hybrid powertrain design will not be reserved exclusively to gasoline fuelled vehicles either.” trol). Another measure presented under the title “Developments for the future” was a “particulate filter with catalytic regeneration” for city busses and community vehicles. Dr. Werner Haas (Klöckner-Humbold Deutz AG Köln) introduced the engine development strategy of his company which included “injection with the aim of fully electronic control” and a “paticulate filter with diesel-oil operated burner” which was still in the experimental stage with some problems still unresolved.
