Diamond & Zebra Electric Mfg. Co., Ltd., a company based in Osaka, Japan, has successfully developed a prototype ignition coil specifically designed for hydrogen-fueled engines. This ignition coil is equipped with a unique function to prevent false ignition, a critical issue when working with highly ignitable hydrogen fuel that easily spreads flame. The company began accepting orders for prototypes from engine manufacturers in October 2024, aiming to support the evaluation and advancement of hydrogen engine technology. The development of engines powered by hydrogen fuel, known for its renewability and lack of CO2 emissions, is increasingly crucial in the fight against global warming. Due to hydrogen's properties, such as high ignitability and low calorific value per volume, advanced ignition systems are necessary to ensure optimal engine performance. Diamond & Zebra's innovative ignition coil, integrated with a false ignition prevention function and high-output capabilities, is poised to be a versatile solution for various hydrogen-powered engines with different specifications. The company believes that this advancement will significantly contribute to the evolution and widespread adoption of hydrogen-fueled engines, crucial for a sustainable and environmentally friendly automotive industry. Looking ahead, Diamond & Zebra is committed to supporting its customers' development initiatives and contributing to society's prosperity through its vision of connecting cars and homes via manufacturing processes. The company's focus on environmental improvement and innovative technologies aligns with its long-term management plan, emphasizing sustainable growth and positive contributions to the global economy.
