Advanced Turbocharged, Direct Injected Gasoline Engines Poised to Take on Diesels in US and in Europe for Reduced Fuel Consumption and Emissions

Green Car Congress

Additionally, suggested one of the speakers, advanced SIDI (spark-ignited, direct-injection) engines can take light-duty market share back from diesels in Europe based on the same trends. Bin 5 engine out is what we’ll need, and then to get it down to Bin 2. the manufacturing can be profitable and also very competitive.
