Numerical analysis reveals biodiesel blends impact combustion efficiency and emissions in diesel engines, suggesting optimization strategies.

Key Points

The research aims to evaluate the combustion and emission characteristics of biodiesel blends in a diesel engine considering varying compression ratios and EGR levels.
Used 3D computational fluid dynamics in ANSYS Forte
Analyzed biodiesel blends B20, B50, and B75 against baseline diesel D100
Conducted a compression ratio sweep from 11:1 to 18:1
Examined thermodynamic impacts of varying EGR levels on emissions
The B75 biodiesel blend shows a 17.48% reduction in brake power compared to diesel.
CR increase to 18:1 raises peak cylinder pressure to 13.59 MPa and temperature to 2913 K for B20.
20% EGR with B50 blend results in 99.58% reduction in NOx emissions, achieving 0.61 g/kg-fuel.
B50 blend reduces CO and UHC emissions by 46.3% and 50.18% compared to diesel.
