My research is focused around enhancing the fuel flexibility of internal combustion engines at high and low loads
Current Project Description:
Ignition delay time and combustion duration of fuels with different octane numbers at various CI engine loads. The combustion properties become insensitive to the fuel supplied at loads beyond IMEPnet = 15 bar.
