摘要: A method of metering a fluid, pollutant-reducing medium, in particular an aqueous urea solution, into motor vehicle exhaust system is proposed, which the fluid medium delivered to nozzle module, or valve, and introduced by module. transport arranged upstream module activated with pulse-width modulation. The associated ensure that, particular, reducing agent metered precisely robust manner relative degrees coldness, use few components.
