Table 5 Assessment of the existing research findings with available relevant studies.
Ref | Test platform | Base fuel | Methanol segment | Cosolvent kind and quantity | Burning evaluation | Mechanical factors | Emissions |
|---|---|---|---|---|---|---|---|
CI engine | Diesel | 10% and 15% by volume | Pentanol (C5); 20% | Enhanced Pcyl., HRR, and ID; lowered CD | Lowered BTE; enlarged bsfc | Lowered soot; enlarged NOx | |
CI engine | Diesel | 20% | Microalgae biodiesel; 40% | Enhanced Pcyl., HRR, CD, and ID; generated two peaks in HRR | Lowered BTE; increased bsfc | Improved soot; reduced NOx | |
CI engine | Diesel | 10% and 15% by volume | – | Enhanced Pcyl., HRR, CD, and ID; generated two peaks in HRR | Lowered BTE; increased bsfc | Lowered Soot; increased NOx | |
Current investigation | CI engine | Diesel | 5%, 10%, and 15% | n-decanol; 20% | Lowered Pcyl. and HRR; increased CD and ID; created two peaks in HRR | Dropped BTE; enlarged bsfc | Dropped NOx and soot; boosted UHC & CO |
