Abstract

An internal combustion engine for motor vehicles, with an intake tube for aspirating combustion air, in which the tube leads to at least one combustion cylinder, and in which tube a throttle valve is disposed. The intake tube effects a mixing of combustion air and fuel vapor downstream of the throttle valve. For the sake of intensive mixing of fuel vapor and combustion air into a largely homogeneous mixture, the fuel vapor generated in a fuel evaporator outside the intake tube is introduced via a delivery device into air turbulence paths that unavoidably develop downstream of the throttle valve in the intake tube as a consequence of the geometry of the intake tube and/or throttle valve.
