Hydrogen combustion engine arrangement and method of operating a hydrogen combustion engine arrangement

Abstract

A hydrogen combustion engine arrangement includes 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 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 an arrangement 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 temperature determining arrangement.
