normal diesel engines. Fuel parameters may have significant impacts on the ability to
operate in HECC modes and on the emissions produced in HECC modes. In this study, 3
diesel-range fuels and 2 oxygenated blends are burned in both normal and HECC modes at
3 different engine conditions. The results show that fuel effects play an important role in the …
High-efficiency clean combustion (HECC) modes provide simultaneous reductions in diesel
particulate matter and nitrogen-oxides emissions while retaining efficiencies characteristic of
normal diesel engines. Fuel parameters may have significant impacts on the ability to
operate in HECC modes and on the emissions produced in HECC modes. In this study, 3
diesel-range fuels and 2 oxygenated blends are burned in both normal and HECC modes at
3 different engine conditions. The results show that fuel effects play an important role in the …
