4. Alcohol Flexible Dual-Fuel Direct Injection Engine
Abstract : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. READ MORE
