Crash-Tolerant System Arrangement in a Motor-Vehicle Engine Compartment

A crash-tolerant system arrangement in an engine compartment situated in a front end region of a motor vehicle, comprising:

• an internal combustion engine situated in the engine compartment and having an engine block;
• an exhaust gas manifold arranged so that it receives exhaust gases of the internal combustion engine;
• an exhaust gas turbocharger, coupled to the internal combustion engine, having an exhaust gas inlet and an exhaust gas outlet;
• an exhaust emission control system having a cylindrical first catalytic converter housing that is situated in front of the exhaust gas turbocharger in a travel direction and in which a first exhaust gas catalytic converter element is situated;
• and
• a first exhaust gas conducting element configured to conduct the exhaust gas from the exhaust gas outlet of the exhaust gas turbocharger to the first catalytic converter housing, the first exhaust gas conducting element extending from the exhaust gas outlet of the exhaust gas turbocharger to an inlet funnel of the first catalytic converter housing so that a pressure force acting on the first catalytic converter housing opposite to the travel direction is at least partially transmitted to the exhaust gas turbocharger,
• wherein the exhaust gas turbocharger is mechanically connected to the exhaust gas manifold via a first fastening device and to the engine block via a second fastening device, the first and the second fastening devices are configured in such a way that a detachment of the connection of the exhaust gas turbocharger to the exhaust gas manifold or a detachment of the connection of the exhaust gas turbocharger to the engine block occurs within a predefined upper value range for the pressure force acting on the first catalytic converter housing opposite to the travel direction.
