Title: METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to a method for operating an internal combustion engine (1) with a liquid or gaseous fuel, wherein at least a portion of the exhaust gas produced during combustion of the fuel is recirculated into an intake tract (7), wherein a fuel-containing liquid medium is provided in a mixing chamber (13) of the intake tract (7) and recirculated exhaust gas is introduced into said liquid medium contained in the mixing chamber (13), the medium is at least partially converted to a gaseous state and this gas mixture is passed through a heat exchanger (10) which is thermally connected to an outlet tract (8), and wherein, in the heat exchanger (10), the gaseous medium absorbs thermal energy from the exhaust gas. In order to provide a further reduction of the emissions and the fuel consumption in the simplest manner possible, the liquid medium contained in the mixing chamber (13) is formed by a dispersion medium (16), the dispersion medium (16) being formed by a mixture of water and fuel, and the gaseous dispersion medium absorbs thermal energy from the exhaust gas in the heat exchanger (10) arranged in the intake tract (7).
