H2 efficient and near zero emissions operation on a SI PFI heavy duty single cylinder engine

Résumé

Driven by legislation and climate change crisis, the automotive industry's interest in renewable and low-CO2-emitting solutions grows. Hydrogen combustion emerges as a solution to reduce emissions over the coming decades, offering a carbon-free composition and a potential renewable production. However, this combustion process may lead to the production of pollutants, such as nitrogen monoxide. This study aims to quantify the key parameters that limit the production of these pollutants based on experiments conducted on a heavy-duty single cylinder engine, spark ignited, retrofitted from diesel to hydrogen with port water injection. These parameters (as air fuel ratio, spark timing or water injection) are examined in terms of performance to propose a clean and highly efficient solution. Results show equivalent power output to it Diesel fuelled equivalent and demonstrate that minimal engine modifications are required to use hydrogen as a fuel in ICE with high efficiency, stable operation and near zero pollutant emissions.
