Towards carbonless engines: the fundamentals of hydrogen compression-ignition

People Involved

Project Description

The current project proposes a novel approach for the use of hydrogen in compression ignition (CI) engine mode, in alignment with UK’s plan for zero emissions by 2040. The use of hydrogen in CI engines (which are typically more efficient than spark ignition engines) has barely been explored due to hydrogen’s high auto-ignition temperature. Thus, in the current work it is proposed the use of H2O2 as an additive that can sufficiently accelerate hydrogen’s ignition. The aim of the current computational work will be the determination of the optimal CI conditions of the hydrogen/H2O2 blends, the identification of the key physical processes and the investigation of the effect of H2O/N2 dilution, through the employment of advanced mathematical tools of asymptotic analysis. The successful adoption of the current project’s outcomes by the automotive industry can render CI engines powered with hydrogen/H2O2 blends an environmentally friendly, sustainable, efficient and affordable solution for automobiles

Two types of transport which are currently challenging to decarbonize and electrify are heavy-duty vehicles (HDVs) and ships. HDVs and ships are predominantly powered by compression ignition (CI) engines fueled with diesel. Hydrogen use in CI engines...
