This coffeesode deep dive discusses the potential of hydrogen as a fuel for internal combustion engines (ICEs). The episode focuses on direct injection (DI) of hydrogen, which has been shown to achieve high engine efficiency and power output with low emissions. The speakers explore different ignition strategies, including spark-assisted ignition and glow-plug-assisted ignition, and propose a new dual-fuel hydrogen-diesel direct injection (H2DDI) mode. The coffeesode also examine the challenges associated with hydrogen DI, such as the need for high injection pressure, and discuss current and future developments in hydrogen injector technology.
