Development of a High-Performance Hydrogen Engine

Stephan Tafel, Bosch Engineering GmbH

In addition to battery EV and fuel cell, the H2 engine is establishing itself as an alternative drive option for climate-neutral mobility. Bosch is already developing series components for H2 engines with a focus on commercial vehicle and off-highway applications. The favorable properties of hydrogen also open up potential for high-performance engines in sports and racing cars, the DNA of Bosch Engineering. In order to make this potential tangible, experts from Bosch Engineering and Ligier Automotive have set up a high-performance vehicle with a 3.0l V6 H2 engine in a joint innovation project in only a few months. The requirements for safe H2 operation in a high-performance and high-speed concept were derived and integrated into the vehicle (storage system, operating strategies, software, etc.). For the integration of the hydrogen storage system, the entire carbon monocoque chassis was newly developed. Special attention was paid to the multi-stage security concept. The presentation shows the engineering challenges in the comprehensive adaptation of the combustion engine and its integration into the entire vehicle including hydrogen storage. With more than 3,000 kilometers on test tracks in Germany and France, the project shows new perspectives and the potential for a climate-neutral sports and racing car drive. The demonstrator confirms the applicability of this technology in a racing series such as the 24 Hours of Le Mans.
