RANS Study on the Impact of Equivalence Ratio on Natural Gas/Diesel-Fueled Combustion in RCCI Engine [PDF]

Journal of Applied and Computational Mechanics
The primary reason in favor of Reactivity Controlled Compression Ignition (RCCI) is that combustion occurs at low temperature, leading to low thermal NOx. Using the RCCI approach is highly demanded due to stringent emission laws.

Experimental Investigation on Spirogyra Biodiesel With Di‐Tert‐Butyl Peroxide as a Cetane Booster

Energy Science &Engineering, Volume 13, Issue 6, Page 3328-3341, June 2025.
Engine tested with third‐generation biodiesel. Cetane improver di‐tert‐butyl peroxide was added to improve combustion. The emissions analysis indicated a 53.8% CO decrease and a 9.1% NO rise to 24.9%. ABSTRACT This study investigates the impact of incorporating 30% spirogyra algae biodiesel (SBD30) with di‐tert butyl peroxide (DTBP) as a cetane booster

Balancing Efficiency and Emissions: A Study on Biodiesel‐Hydrogen Dual‐Fuel Engine Performance Under Varying Injection Timings

Engineering Reports, Volume 7, Issue 5, May 2025.
This study explores the impact of varying injection timings on a biodiesel‐hydrogen dual‐fuel CI engine. Results reveal that IT30 optimizes brake thermal efficiency (32.7%) and reduces CO and HC emissions while slightly increasing NOx. Findings suggest IT30 as the optimal configuration for balancing efficiency and emissions. ABSTRACT The growing demand
