<p>The invention relates to an internal combustion engine 10 for a vehicle. The engine comprising of at least one air pipe 18 for guiding air to at least one combustion chamber 14 of the internal combustion engine and at least one exhaust pipe 28. The engine further comprises at least one compressor 20 arranged in the air pipe and at least one catalytic converter 34 arranged in the exhaust pipe. The engine further comprises at least one connection line 56 fluidically connected to the air pipe downstream of the compressor and fluidically connected to the exhaust pipe upstream of the catalytic converter. The connection line comprises two connection points 58 60, a two-way valve 62 being configured to allow both a flow of air from the air pipe into the exhaust pipe and a flow of exhaust gas from the exhaust pipe into the air pipe. The first connection point may be arranged upstream of a cooling device 52 in the air pipe. The two-way valve may be electronically controlled. The engine may during a warm-up phase be configured to branch off exhaust gas through the connection line into the air pipe.</p> |
