Abstract

The electrification of the two-wheel vehicle segment is an important strategy for decarbonising the transportation sector. This study aimed to assess the hybridisation of gasoline motorcycles with battery electric systems as an option for decarbonisation. A gasoline motorcycle that had been converted to a hybrid motorcycle was evaluated in several aspects: energy consumption, greenhouse gas (GHG) emission, and cost of energy. The vehicle was tested under the United Nations economic commission for europe (UNECE) Regulation No.40 and compared to a battery electric motorcycle. The test in internal combustion engine (ICE) mode consumed 233.31 Wh/km of specific energy, emitted 60.69 gCO2/km and cost 1.65 US-cent/km on average. The test in hybrid mode consumed specific energy at 6 % higher and 4 % lower specific energy consumption than ICE, thus not improving the carbon dioxide (CO2) emission and operating cost. In electric battery mode, energy consumption was saved by 83 %, with 35 % lower CO2 and 74 % cost savings. The battery electric motorcycle runs more efficiently with 88 % lower energy consumption, 53.8 % lower CO2 and saved cost by 82 %. If the hybrid controller is improved in future development, it could lower specific energy consumption by 41.7 %, reduce CO2 by 11.2 % and save cost by 35.7 %.

Abstract

Hydrogen peroxide (H2O2) enrichment is known to enhance combustion efficiency in diesel engines; however, its application as an emulsion is restricted by phase instability in the absence of chemical surfactants. This study investigates the stability and temperature characteristics of non-surfactant emulsions produced using an inline mixer known as the Real-Time Emulsion Supply System (RTES). Four emulsion types were formulated using water and aqueous H2O2 (5-15 vol%) as the dispersed phase, with neat diesel (B0) and biodiesel (B35) serving as the continuous phase: water-in-B0 (WD), H2O2-in-B0 (HD), water-in-B35 (WB), and H2O2-in-B35 (HB). The emulsions were prepared using RTES with a residence time of 180 s. During the preparation, the temperature was continuously recorded using a Graphtec GL840 data logger. The phase separation was monitored over 600 s using a Canon-EM3 camera. Results demonstrate that B35-based emulsions exhibit higher stability compared to B0-based emulsions. The stability tests showed distinct phase separation ratios for each formulation: 12.67% for WD, 10.67% for HD, 4.67% for WB, and 4.27% for HB. Meanwhile, the temperature rise (ΔT) varied slightly by formulation, ranging from 1.67-1.97 °C for WD and HD, and from 2.33-2.73 °C for WB and HB.
