UNSW Hydrogen Retrofit System

Education and Research

Education and Research

A system that converts diesel engines to run on 90 percent hydrogen by injecting H2 directly into the cylinder with independent injection timing control for both H2 and diesel systems.

A method that forms pockets of higher and lower hydrogen concentrations within the combustion chamber, enabling the use of lower-purity hydrogen fuel while reducing nitrous oxide emissions.

Australia

A retrofit system that converts existing diesel engines to run on 90 percent hydrogen fuel while maintaining 10 percent diesel operation. The system includes H2 injection directly into the cylinder, independent injection timing control for both fuels, and stratification techniques to reduce the need for high-purity hydrogen.
