    摘要: 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.

    摘要: An internal combustion engine assembly comprises: a fuel tank for containing fuel comprising alcohol, a reformer unit being in heat exchanging contact with exhaust gases from an exhaust system, for steam reforming of alcohol, a water supply unit connected to a water steam inlet of the reformer unit, and a distiller unit being with a fuel inlet connected to a distiller supply duct that is connected to the fuel tank, an alcohol outlet of the distiller unit being connected to the inlet of the reformer unit. The increased alcohol concentrations at the inlet of the steam reformer result in improved efficiency of the reforming process.
