ABSTRACT:
In a transverse-mounted cylinder-in-line internal combustion engine (1) fitted in a motor vehicle, the exhaust gases from the side of the internal combustion engine opposite to the direction of travel are led forwardly round the internal combustion engine and from there reach an NOx trap (8) arranged in the middle region of the vehicle. For rapid heating up on cold starting the three-way converter (12) is arranged immediately after the exhaust manifold (2), and in addition when a valve (9) is closed the exhaust gases are led through a short supply duct (5) directly to an exhaust duct (13) which opens into an NOx trap.
