Abstract
The invention relates to a device for humidifying the intake air of internal combustion engines that are equipped with a turbocharger. The device comprises a humidifying unit (14, 16) through which the intake air and humidifying liquid flow and come into contact with one another. The humidifying unit is arranged upstream from the compressor (6) of the turbocharger in the direction of flow of the intake air. A heat exchanger (13, 15), which serves to pre-heat the intake air and through which the atmospheric intake air flows, is located upstream from the humidifying unit in the flow path of the intake air. Said heat exchanger is connected to a liquid circuit (11, 21) with which the humidified intake air that is compressed by the compressor and supplied to the internal combustion engine is cooled by another heat exchanger (9).
