A simulative investigation for transient engine development involving methanol and ammonia fuel blends Bhawandeep Sharma・Madan Kumar (Guangdong Technion Israel Institute of Technology) Transient operated vehicles have significantly contributed to higher GHG emissions due to combustion complexity. Considering this challenge, renewable fuels such as methanol and ammonia are studied in transient conditions. The work includes comprehensive experimental and numerical analysis of methanol-ammonia blends for genset engine. The analysis focuses on the performance, combustion and emissions by tuning load, injection timing, spark timing, and blend ratio. Results indicate that increasing ammonia in the fuels increases indicated efficiency. Moreover, more ammonia percentage in the fuels leads to decrement in NOx and CO2. However, BSFC and combustion duration increased due to slow combustion properties of ammonia. |

Research on Small Two-stroke Opposed Piston Power Unit Akira Iijima・Yoshiaki Yamazaki・Jinru Liu・Shumpei Fukushima・Yusuke Otaki・Ikumi Okawara・Sou Watanabe (Nihon University) Internal combustion engines for electric powertrains are required to have high power density, high thermal efficiency, and low vibration and noise characteristics. As an engine that can achieve such characteristics, we focused on the two-stroke opposed piston engine. In this study, a small two-stroke opposed piston engine have prototyped and investigated its basic combustion characteristics. |
