Spray-Guided Direct Injection: The Potential of Turbocharged Gasoline Engines

摘要

A 2.0 1 turbocharged FSI engine forms the basis for the analysis of spray-guided combustion with central location of injector and spark plug. The long duration experience in the field of the Volkswagen brands since introducing the first generation of gasoline direct injection into market in 1999 stands for competence in the domain of gasoline Direct Injection (DI). Since the 1970s, stratified charge in DI gasoline engines has been the focus of a wide range of investigations. Currently, the largest potential in terms of a custom-errelevant reduction in fuel consumption can be seen in the spray-guided combustion process with centrally located injectors and outward opening nozzles [1, 2].
