Abstract
An arrangement is provided for feeding a liquid additive from a receptacle into a fuel line or into an exhaust line of an internal-combustion engine of a motor vehicle by way of a blockable feed line leading into at least one of the above-mentioned line and by way of a pump which at least temporarily generates a feed pressure in the feed line. The receptacle can be filled with additive from a larger storage tank also accommodated in the motor vehicle by way of a connection line that can be blocked. The feed line branches off the connection line between the receptacle and the storage tank. The pump is installed in the receptacle or between the receptacle and the branching-off of the feed line into the connection line. The connection line can be shut-off in the storage tank or between the storage tank and the branching-off of the feed line.
