Kawasaki has made significant progress in its motorcycle project involving a hydrogen internal combustion engine by conducting physical testing on a prototype on a track. Building upon the Ninja H2 SX-based concept unveiled earlier this year, Kawasaki has reengineered the 998cc supercharged in-line-four motor to enable direct injection of hydrogen into the cylinders. This prototype showcases the potential of hydrogen combustion as an alternative to battery and hydrogen fuel cell electric options, offering a cleaner solution for air quality concerns. The prototype's integration of the fuel supply system and hydrogen tanks into the chassis design highlights the innovative approach taken by Kawasaki. With hydrogen combustion emitting only water and minimal CO2, this technology presents a sustainable and environmentally friendly option for future mobility. The project leader, Satoaki Ichi, emphasizes the advantages of hydrogen engines, noting their responsive feel and cleaner emissions. Kawasaki's plans to introduce hydrogen-fueled internal combustion engine motorcycles in the early 2030s align with the company's commitment to sustainable transportation. The article also mentions the Hydrogen Small Mobility & Engine Technology joint venture involving major Japanese manufacturers, focusing on advancing hydrogen mobility solutions for the future.
