ABSTRACT:
In a turbocharged diesel engine, the charge air is cooled in a charge air cooler designed as an injection intercooler. The water which has been introduced into the working medium of the diesel engine in the charge air cooler, after the working medium has been expanded, is condensed out of the exhaust gas by means of a condenser and a separator and is returned to the charge air cooler. According to the invention, the engine is started without injection of externally supplied water into the charge air cooler. Water which forms during the combustion in the diesel engine is condensed out of the exhaust-gas stream and returned to the charge air cooler. Additional water vapor formed continuously during operation through combustion of diesel fuel is likewise condensed out and introduced into the charge air cooler. In this way, the working medium is laden with moisture until the water mass flow that can be separated out of the exhaust gas is sufficient for the set cooling power of the charge air cooler. Further combustion water that is formed can be used for other purposes. In this way, engines with internal combustion in which water is introduced into the working medium can be operated without an external supply of water.
