本研究は、ディーゼルバスに水素化処理植物油（HVO）を混合した際の排出ガス削減効果を実走行条件で測定した。NOx排出量がHVO混合率に比例して減少し、高混合率（HVO70）で最大23%削減可能であることを示した。HVOは既存車両に適合し、2030年までの気候・大気質目標達成に有用な手段である。
English
This study reports experimental results from a diesel bus using HVO blends under real-driving conditions. NOx emissions decreased proportionally with HVO content, with up to 23% reduction for HVO70. HVO can help meet 2025-2030 climate and air quality targets alongside electrification.

📄 Abstract（原文）
Advanced biofuels represent a key option for transport decarbonization, particularly in sectors where electrification is constrained by technical and economic barriers. Their compatibility with existing vehicle fleets and fuel distribution infrastructure enables rapid deployment without the need for major capital investments. In local public transport, biodiesel (FAME), hydrotreated vegetable oil (HVO), and biomethane are mature solutions capable of delivering greenhouse gas emission reductions of 60–90% compared with fossil fuels. Among these, HVO is particularly promising, as an extensive body of literature has consistently shown its potential to significantly reduce engine-out emissions, especially particulate matter (PM) and nitrogen oxides (NOx). This study reports the results of an experimental campaign carried out on a diesel-powered local public transport bus equipped with a Euro III engine and lacking particulate matter and NOx after-treatment systems. Emissions were measured using a portable emissions measurement system (PEMS) under real driving conditions, operating the vehicle with neat diesel, a 15% HVO blend, and a 70% HVO blend. Tests were conducted over urban and extra-urban routes. The results show that NOx emissions decrease proportionally with increasing HVO content, with high-blend ratios (HVO70) yielding estimated reductions of approximately 13–18%, and up to 23% under carefully controlled and comparable urban driving conditions. Based on these findings and the existing literature, HVO proves to be a useful instrument to meet 2025–2030 climate and air quality targets (particularly NOx and PM emission reductions), alongside electrification and modal shift measures, if used in public transport fleets.
