In developing high speed swirl supported direct injection diesel engines it has been a general experience that different engine results (performance, smoke and emission) may be obtained when using ...

Diesel and gasoline emissions have become some of the leading concerns regarding greenhouse gases and global climate change. While diesel engines are more efficient than gasoline-powered engines, they ...

Reduced emissions from the spark-ignition engine, when fueled by gasoline containing small amounts of MTBE, have led us to explore similar positive results in compression-ignition (CI) engine ...

Direct numerical simulations let researchers improve combustion efficiency and lower pollution in diesel engines. “Cool flames” may sound contradictory, but they could lead to better engine designs ...
