- •
Newly developed reduced ethanol mechanism (47 species and 272 reactions) used.
- •
Engine maps over wide range are developed for performance and emissions parameters.
- •
HCCI operating range increases with compression ratio & decreases with engine speed.
- •
Maximum combustion efficiency up to 99% and thermal efficiency up to 50% is achieved.
- •
Maximum N2O emission found up to 2.7 ppm and lower load have higher N2O emission.
