Internal combustion engine with a fuel reformer and exhaust gas recirculation

An internal combustion engine assembly includes a fuel tank, connected via a fuel supply duct to a first fuel inlet of a cylinder, the cylinders with an outlet connected to an exhaust system. Exhaust gases from the exhaust system are in heat exchanging contact with a reformer unit for steam reforming of alcohol, the reformer unit being with a reformer outlet connected to a to a second fuel inlet of the cylinders for supplying hydrogen to the second fuel inlet. An alcohol evaporator is in heat exchanging contact with the exhaust gases. A water evaporator is in heat exchanging contact with the exhaust gases. A reformer purge duct extends from the exhaust system to the inlet of the reformer unit via a purge control valve, adapted for feeding exhaust gases into the reformer unit and via the reformer outlet to the second fuel inlet of the cylinders.
