Numerical investigation of performance, combustion and emission fuelling with hydrogen in a spark ignition engine.

Global greenhouse gas emissions resulting in
climate change are the concerns for researchers and
policymakers. As per compliance with Net Zero emissions by
2050, it is obligatory to explore sustainable fuels for internal
combustion engines. Aiming this target, a numerical model was
developed using GT-Suite software for hydrogen port injection
in a single-cylinder, four-stroke gasoline engine. The reason for
choosing hydrogen is that green hydrogen is the cleanest fuel and
can be produced from renewable sources. The model was
developed to provide performance, combustion, and emission
data for both hydrogen port injections. The performance data
included brake power, brake mean effective pressure, and brake
thermal efficiency, while the combustion data included incylinder pressure, rate of heat release, and in-cylinder
temperature. The hydrogen port injection performance,
combustion and emission data were compared with those of
gasoline port injection. Compared to gasoline port injection, no
significant variations in performance and combustion data were
observed with hydrogen port injection. However, Carbon
dioxide emissions were entirely removed with hydrogen p
