Summary: This study investigated the effect of pyrolysis oil from waste cooking oil on diesel engine performance and emissions, finding that oil blends with diesel can lead to changes in combustion characteristics and emissions. Pyrolysis oil can be used as an alternative fuel to diesel in suitable proportions, although high blend ratios may result in decreased engine performance.

Summary: This study characterized the emissions of semi-volatile organic compounds (SVOCs) from a commercial diesel engine in both gaseous and particulate phases using GC x GC-ToFMS. The results showed that the distribution patterns of gaseous SVOC emissions were similar to diesel fuel, while those of particulate SVOC emissions were strongly associated with lubricating oil. The contributions of diesel fuel and lubricating oil to SVOC emissions were evaluated using the PMF method, and it was found that diesel fuel contributed to SVOC emissions at low load, while lubricating oil dominated at high load. Combustion by-products also had a significant contribution to SVOC emissions.

Summary: This study aimed to optimize the performance of a direct injection diesel engine by utilizing a ternary blend of diesel, biodiesel, and 1-hexanol. The fuel injection timing and exhaust gas recirculation (EGR) were optimized using response surface methodology (RSM). The HX20 blend (diesel 50 v/v% + biodiesel 30 v/v% + 1-hexanol 20 v/v%) injected at lesser fuel injection timing and EGR rate showed the best emission and performance characteristics.

Summary: In this study, waste fish oil was utilized to produce biodiesel and emulsion fuels, which were then tested in a diesel engine to evaluate performance and emissions. Through multi-objective optimization, the best emulsion fuel formulation was identified, resulting in simultaneous reduction of CO, unburnt hydrocarbon, and nitrogen oxide emissions compared to neat diesel fuel.

Summary: In this study, a high stability deoxygenation catalyst was prepared from agricultural waste and used for the production of green diesel fuel. The catalyst was coated with a nanofilm aluminum protective layer to enhance its stability and prolong its lifetime. The results showed that the deoxygenation reaction is a first-order reaction and the coated catalyst has a lower deactivation rate.

Summary: The study explored the production and properties of biofuel from waste cooking oil, comparing it to traditional diesel fuel in terms of viscosity, density, emissions, and engine performance. The higher density of biofuel had a negative impact on emissions and engine performance, highlighting the need for new biofuel formulations to optimize engine performance and environmental impact.
