An auxiliary combustion air supply arrangement for an internal combustion engine having a combustion air supercharger driven by an exhaust gas turbine. During time periods characterized by lack of sufficient exhaust gas energy, in order to increase the supply of air to the intake manifold of the engine, auxiliary combustion air is obtained directly from a compressed air tank and is supplied to the intake manifold via an appropriate control mechanism. A delay element as part of the fuel injection system is provided, whereby the control mechanism as well as the delay element are actuated by operation of a gas pedal, as a result of which the supply of auxiliary combustion air precedes the fuel injection, with injection of the full fuel injection quantity not being initiated until later.
