Abstract
An exhaust-gas tract for a motor vehicle has an exhaust-gas burner that includes an air inlet connection for the introduction of air into the exhaust-gas burner. The air inlet connection has a connection piece in which a check valve for the closure of the connection piece is arranged. The air inlet connection has an air inlet flange which connects the connection piece to a combustion chamber of the exhaust-gas burner and which seals off the combustion chamber. A motor vehicle incorporates the exhaust-gas tract.
