There are a number of advantages that hydrogen offers over traditional fossil fuels when it comes to
engine fuel. In comparison to traditional fuels, hydrogen offers clean combustion, low ignition energy, a
wide flammability range, a greater flame speed, minimum diffusion risk, and a high energy density. This
study examines the impact of different hydrogen injection angles on the emissions and performance of an
engine. The computational fluid dynamics method is applied to examine hydrogen injection performance in
diesel engines with commercial software. Performance parameters, combustion pressure, temperature inside
the combustion chamber and heat release rate, together with the emissions parameters CO and NOx are
investigated. The highest combustion pressure is determined at 30° and 45° spray angles. The maximum
temperatures for hydrogen injection angles of 15°, 30°, and 45° were found as 1330 K, 1335 K, 1290 K,
respectively. At a 30% hydrogen injection angle, combustion and emissions were found to be optimal.
