    • A method for providing a reducing agent-containing gas flow in the exhaust system of an internal combustion engine includes providing at least one reducing agent precursor, evaporating the precursor to provide a gas flow, at least partially heating the gas flow to temperatures of at least 250° C., at least partially converting the precursor in the gas flow to a reducing agent and adding the reducing agent-containing gas flow to the exhaust of the engine. The method and a device provide a reducing agent-containing gas flow in a quantity being easily controllable and adaptable to dynamic changes especially in exhaust systems of mobile applications such as automobiles. A temperature of a first zone is kept at 150° C. or just below while a temperature of a second zone is kept at more than 300° C. A hydrolysis catalytic converter is hardly cooled upon receiving the precursor as a vapor, positively affecting the method.
    • 一种用于在内燃机的排气系统中提供含还原剂的气流的方法,包括提供至少一种还原剂前体,蒸发前体以提供气流,至少部分地将气流加热到至少 250℃,至少部分地将气流中的前体转化为还原剂,并将含还原剂的气流加入到发动机的排气中。 该方法和装置提供了一种易于控制并适应动态变化的量的还原剂气体流,特别是在诸如汽车的移动应用的排气系统中。 第一区域的温度保持在150℃或刚好在第二区域的温度保持在大于300℃的温度。水解催化转化器在接收作为蒸汽的前体时几乎不被冷却,从而对 方法。
