摘要： This exhaust arrangement for an exhaust line having an exhaust gas treatment device and a liquid injection device located upstream of the exhaust gas treatment device includes a single moving element incorporating a throttling member having a solid closing surface and, operatively connected to the throttling member, a turbulence generating member and an actuator for controlling the position of the moving element between a first position wherein the moving element is in a retracted position and creates a minimum back pressure in the exhaust line and a second position wherein the moving element is in an extended position and creates a maximum back pressure, or selectively in at least one intermediate position wherein the moving element is in a turbulence generating position wherein the turbulence generating member intrudes at least partially into the exhaust line and creates turbulences within the flow of exhaust gases.
