Promotion effect of hydrogen addition in selective catalytic reduction of nitrogen oxide emissions from diesel engines fuelled with diesel-biodiesel-ethanol blends

Sak Sittichompoo et al.

Summary: The study examines the combustion effects of ethanol and palm oil biodiesel blends with diesel, as well as the impact of hydrogen on catalyst performance. Results show that increasing ethanol content can reduce NOx emissions but lead to higher CO and THC concentrations, while the addition of hydrogen significantly enhances NOx reduction activity.

Optimization and investigation the effects of using biodiesel-ethanol blends on the performance and emission characteristics of a diesel engine by genetic algorithm

Alireza Shirneshan et al.

Summary: The research investigated the combined effects of biodiesel-ethanol fuel blends on a diesel engine's performance and emission parameters using response surface methodology. Results showed that increasing ethanol in the fuel mixture decreased brake power and torque, while improving BSFC. Higher ethanol percentage led to reduced smoke and NOx emissions, while higher biodiesel percentage reduced CO emissions. Genetic algorithm optimization showed optimal conditions with 94.65% biodiesel, 2800 RPM, and 65.75% engine load. Ethanol was found to be more effective in improving emission characteristics than performance characteristics.
