Abstract
The invention relates to a dosing system (10) for introducing a reducing agent (18), especially urea or an aqueous urea solution, into an exhaust gas system of an internal combustion engine. The dosing system (10) comprises a reservoir (12, 14) for accommodating a stock in the reducing agent (18), a delivery unit (32), a level sensor (50) and a dosing module (38). The reservoir (40) is a standard reservoir integrated into a vehicle-specific component (60), especially a fuel tank (68).
