1. A hydrogen combustion engine arrangement, comprising:
a source of hydrogen;
an internal combustion engine having at least one cylinder having an inlet opening connected by first hydrogen supply line to the source of hydrogen and an outlet opening;
an exhaust aftertreatment system (EATS) connected by an exhaust line to the outlet opening of the at least one cylinder, the EATS including a selective catalytic reduction system (SCR), a combustion zone upstream of the SCR, the combustion zone being connected to the source of hydrogen by a second hydrogen supply line, and a means for determining a temperature in the EATS; and
a computer system configured to control delivery of hydrogen to the EATS in response to a signal from the means for determining a temperature.
