To attain a stable radial mixture layering, it is provided that the fuel injection valve is disposed in the second intake conduit, and the throttle device in the closed state produces a defined minimum flow rate of between about 5% and about 20%, preferably about 10%, of the maximum flow rate, and that viewed in the direction of the crankshaft axis the center line of the first intake conduit in the intake valve region has a greater radius of curvature than does the center line of the second intake conduit.
