CO and NMHC are key indicators of incomplete combustion: CO results from partial oxidation of carbon during fuel burning, and NMHC represents the fraction of unburned hydrocarbons excluding methane. Both pollutants decreased markedly with renewable fuels, indicating a more complete oxidation process promoted by HVO’s paraffinic composition and FAME’s oxygenated nature.Experimental results show that HVO and HVOB20 slightly increase brake torque and reduce BSFC compared with fossil diesel, despite their lower density and heating value. Combustion remained stable across all operating conditions, with negligible variations in ignition delay and pressure rise rate. NOₓ emissions were comparable or marginally higher at medium engine speeds, likely due to faster ignition and elevated combustion temperatures. Unregulated species such as HCHO and N₂O decreased or remained negligible with increasing renewable content, while PNC and count mean diameter (CMD) were significantly reduced, confirming cleaner combustion and reduced soot formation.Overall, both HVO and HVOB20 demonstrated improved combustion efficiency and emission performance while ensuring full engine operability without calibration adjustments. These findings confirm the technical viability of renewable diesel fuels as immediate, drop-in solutions for reducing GHG emissions.]]> Tue, 14 Apr 2026 15:11:25 GMT https://trid.trb.org/View/2692283 Assessing Energy Use, Cost, and Emissions of Small Regional Rail Vehicles: Methodology and Case Study on a German Track https://trid.trb.org/View/2692264 Tue, 14 Apr 2026 15:11:25 GMT https://trid.trb.org/View/2692264 Application of Waste Cooking Oil–Steel Slag in Dry Process Preparation of Rubber Asphalt Mixtures https://trid.trb.org/View/2651467 Thu, 26 Mar 2026 17:03:06 GMT https://trid.trb.org/View/2651467 Effect of different warm mix additives on the thermal history dependence of crumb rubber modified asphalt binder https://trid.trb.org/View/2643696 Sun, 22 Mar 2026 17:19:37 GMT https://trid.trb.org/View/2643696 Influence of Bio-Oil on the Performance and Microstructure of Rejuvenated Asphalt Binder https://trid.trb.org/View/2632955 Tue, 17 Mar 2026 16:15:50 GMT https://trid.trb.org/View/2632955 Study on Road Performance of SBS-Modified Asphalt Mixtures Regenerated from Waste Soybean Oil https://trid.trb.org/View/2613073 Fri, 20 Feb 2026 15:28:21 GMT https://trid.trb.org/View/2613073 Biodiesel Production via Homogeneous Route (KOH) and Heterogeneous Route (K2O/Nb2O5) https://trid.trb.org/View/2669812 Tue, 17 Feb 2026 10:32:32 GMT https://trid.trb.org/View/2669812 Construction of molecular models of modified waste cooking oil rejuvenated bitumen and nanoscale analysis of thermodynamic and structural properties https://trid.trb.org/View/2640009 Thu, 12 Feb 2026 08:53:23 GMT https://trid.trb.org/View/2640009 Effect of catalytic esterification of waste cooking oil on the rejuvenation performance of aged asphalt https://trid.trb.org/View/2639982 Thu, 12 Feb 2026 08:53:23 GMT https://trid.trb.org/View/2639982 Investigation on the self-healing properties of rejuvenated asphalt prepared from pre-desulfurised crumb tire rubber using waste cooking oil https://trid.trb.org/View/2618020 Mon, 09 Feb 2026 13:55:11 GMT https://trid.trb.org/View/2618020 The rejuvenation effects of colza bio-oil on aged SBS modified bitumen: a multiscale performance study https://trid.trb.org/View/2618018 Mon, 09 Feb 2026 13:55:11 GMT https://trid.trb.org/View/2618018 Comprehensive analysis of the performance and economic viability of rejuvenated asphalt modified with tall oil: Experimental and molecular simulation approaches https://trid.trb.org/View/2639633 Fri, 06 Feb 2026 13:54:23 GMT https://trid.trb.org/View/2639633
