Research on Transient Performance of PFI Hydrogen Internal Combustion Engine

Hydrogen, as a clean fuel, holds the potential to become a solution for transitioning traditional internal combustion engines. Under steady-state conditions, turbocharged hydrogen internal combustion engines can achieve zero carbon emissions through lean combustion. However, under transient conditions with rapid load changes, the transient performance and emissions of hydrogen engines pose significant challenges. In this paper, transient performance tests were conducted on a 4-cylinder turbocharged port-fuel injection hydrogen internal combustion engine, including constant speed load testing(800rpm-2000rpm) and the World Harmonized Transient Cycle test(WHTC). The transient response performance and emissions of the hydrogen engine were evaluated, and the test results were analyzed accordingly.
