Saito et al.35
|
Re-entrant chamber |
100% diesel (experimental) |
Shall depth and re-entrance CC |
Lowered BSFC, less emissions |
Zhu et al.36
|
TRCC |
100% diesel (experimental) |
Pip area, torus radius, piston bowl lip area |
Improved air-fuel mixing, lowered emission, high performance |
Dolak et al.37
|
Stepped bowl chamber |
100% diesel (simulation) |
Swirl, modified spray angle, fuel injection rate |
Lowered SFC at part and full load, less CO and soot precursors |
Lim et al.38
|
Bowl-in-piston (Mexican hat shaped) |
100% diesel (simulation) |
Different spray angles (70, 100 and 130 deg) |
Lowered NOx emissions and soot (about 6.8%) for 70 deg spray angle with Mexican hat shaped geometry |
Shi et al.39
|
Quiescent |
100% diesel (experimental) |
Swirl ratio inducement, spray target with part and high load variation |
Full load with swirl resulted in higher performance and minimized emissions |
Wickman et al.40
|
Re-entrant chamber |
100% diesel (simulation) |
EGR, Swirl ratio, SOI, injection pressure and compression ratio |
Lowered BSFC, CO, NOx and CO2
