<p>1. Internal combustion engine with exhaust gas turbocharging with an exhaust gas line system to at least one exhaust gas turbocharger and a charging air line system into which at least one compressor of the exhaust gas turbocharger delivers combustion air, and with a device for additionally supplying vaporisable liquid, in paricular water, in addition to the fuel supplied to the internal combustion engine, which device is connected to the exhaust gas line system and the charging air line system or the combustion chambers of the internal combustion engine and injects liquid intermittently into the exhaust gas line system and/or into the charging air line system or into the combustion chambers, the device for supplying liquid being formed by a reservoir, a pump, connecting lines and at least two valves, the first valve controlling the supply of liquid to the exhaust gas line system and the second valve controlling the supply of liquid to the charging air line system or to the combustion chambers, characterized in that to increase the charging pressure under certain operating states of the internal combustion engine, air and fuel are additionally introduced into the exhaust gas line system (4), in that the first valve (96) is controlled as a function of a control valve (48) in an air circulation line (46) between the charging air line system (6) and the exhaust gas line system (11), and in that the second valve (98) is controlled as a function of the charging pressure in the charging air line system (6).</p> |
