A method and apparatus control the power to be delivered by a mixture-compressing internal combustion engine which, during normal operation of the internal combustion engine, is adjusted by matching the fuel injection quantity to the induced air mass flow corresponding to the current load demand and controllable by a setting element. So that control of the internal combustion engine power to be delivered remains possible (emergency driving function) in the case of an impairment of the function of the setting element for controlling the induced air mass flow but, at the same time, so that a reduction in the volumetric efficiency of the internal combustion engine is not to be expected in normal operation, the internal combustion engine power is adjusted to the value corresponding to the current load demand during the period of the functional fault exclusively by interventions in the mixture composition and/or by interventions in the ignition and/or by controlled interruption of the fuel delivery to at least one cylinder (i.e. cylinder shut-down).

Power-controlling method for controlling mixture-compressing internal

A passenger motor vehicle with a fuel tank arranged to the rear of the rear seats within a space which is provided with inflow openings for dynamic air flow and/or with inflow openings for exhaust air out of the vehicle interior of motor vehicles equipped with an air-conditioning system, and with outflow openings to enable the discharge of air out of the fuel tank space.

Passenger motor vehicle with a tank arranged behind the rear seats

An internal combustion engine with a return line for exhaust gases which connects the exhaust system with an inlet line provided with a throttle valve; the orifice of the return line in the inlet line is thereby located within the control cross section of the inlet line so that with a closed and substantially closed throttle valve, the orifice is upstream of the throttle valve whereas with an opened or substantially opened throttle valve, it is disposed downstream thereof.
