Summary

The Volvo group has committed to have a CO₂ neutral product fleet offer by 2040. Important pillars to achieve CO₂ neutrality are the battery electric vehicles and the H₂ fuel cell products, but Volvo also recognises the need to keep combustion engines for certain applications, for example operations with very high up-time and/or in very rough environments with high payloads. 

The development of a H₂ engine demonstrator based on the present 780hp 17L diesel platform will be presented in this paper. In the previous paper [1] the digital development was described. Now the focus is to describe the results from testing of the demonstrator engine. Key results include peak torque of 3000 Nm at 1000 rpm, maximum power approaching 600 hp at 1600 rpm, peak brake efficiency exceeding 42% and the possibility of engine -out emissions of NOx at approximate EuroVI tailpipe levels. 

Furthermore, the potential of the Volvo Ultra Lean concept will be described and discussed with the latest updates, including potential hybridisation.
