Beschreibung
Zusammenfassung:	Internal combustion engine with hydrogen direct injection equipped with: - a cylinder head (100) equipped with at least one injector (20) configured to inject a spray (21) of hydrogen, - at least one piston (10) - a combustion chamber (40) of the piston (10) has a non- symmetrical geometry with a first portion (41'), proximal to the injector (20) less deep than a second portion (41"), distal to the injector (20), the non-symmetrical geometry having the function of capturing most of the hydrogen spray (21 ) and avoiding direct impact of the hydrogen spray (21) on the walls (42', 42 ") of the combustion chamber (40), as well as favoring the best mixing towards the center (43) of the combustion chamber (40), and - a connection channel (23) between the injector (20) and the combustion chamber (40) is provided with a converging section (22) configured to reduce an opening angle (γ) of the hydrogen spray (21).
