<p>1. The invention relates to a device for feeding liquid and/or vaporous water into the intake manifold (40) of an internal-combustion engine containing a water tank (10), a heat exchanger (22) between the water and exhaust gas, and a heat barrier (201, 84, 98 ; 201, 84, 120) placed before the heat exchanger which consists of a valve (201, 84) gating backwards to the direction of the water stream and a valve element (98, 120) which can not be opened by the intake suction pressure, and further containing a dosing unit (18, 154, 156) dosing the amount of water being fed to the intake manifold, and a control unit (11, 162), controlling the dosing unit (18, 154, 156) depending from at least one parameter of operation of the internal-combustion engine, comprising a device (24, 26, 128, 11) controlling the temperature of the liquid and/or vaporous water being fed to the intake manifold (40) depending from parameters of operation which are delivered by at least one sensor placed at the internal-combustion engine e.g. a temperature sensor (48, 50), a suction pressure sensor (60), or a rotational speed sensor as a breaker contact (64).</p> |
