Abstract

An apparatus and method for operating a piston driven internal combustion engine having an exhaust gas turbocharger, provides for the exhaust gases of the cylinders to be conducted to an afterburner chamber and subsequently to the exhaust gas turbine of the turbocharger when the motor vehicle is coasting, i.e., when the motor vehicle and engine are being driven by the vehicle's inertia, with the ignition for the cylinders being turned off and the charging air being introduced into the afterburner chamber. The noncombusted fuel/air mixture from the cylinders is combusted in the afterburner chamber with the additional charging air to thereby bring the turbocharger to its full output for reacceleration of the engine.
