Diamond & Zebra Electric Mfg. Co., Ltd., a company based in Osaka, Japan, has successfully developed a prototype of an ignition coil designed for hydrogen-fueled engines. The newly developed ignition coil comes equipped with a fail-safe mechanism to prevent false ignition caused by the ignition system. This innovation is essential as engines powered by hydrogen fuel are becoming increasingly popular as a solution to combat global warming due to their CO2-free nature. Hydrogen fuel is known for its high ignitability and the ease with which it spreads flames. This poses a challenge as even slight heat or electrical energy can lead to false ignition at unintended timings. Additionally, due to hydrogen's low calorific value per volume, specialized ignition systems capable of high-voltage output are required to ensure engine efficiency, especially for applications like supercharging and high compression. Diamond & Zebra's prototype aims to address these challenges by incorporating a false ignition prevention function within a high-output ignition coil. This development is expected to be applicable to a wide range of hydrogen-fueled engines with different specifications, thus playing a significant role in promoting the advancement of hydrogen-powered vehicles. The company's long-term vision, as outlined in its management plan 'Scrum of Fire,' focuses on contributing to the enhancement of the global environment by bridging the gap between automotive and residential spaces through manufacturing. This latest innovation not only showcases Diamond & Zebra's commitment to customer satisfaction but also emphasizes its dedication to societal prosperity through sustainable technological advancements.
