Abstract: An exhaust aftertreatment system may include a reductant tank, a reactor system, a storage tank, a first conduit and a second conduit. The reactor system may receive reductant from the reductant tank and may output a gas comprising ammonia. The storage tank may receive gas comprising ammonia from the reactor system and may store a volume of gas comprising ammonia. The first conduit may communicate gas comprising ammonia from the reactor system to a stream of exhaust gas. The first conduit may bypass the storage tank. The second conduit may communicate gas comprising ammonia from the storage tank to the stream of exhaust gas.

Abstract: An exhaust aftertreatment system may include a reductant tank, a gaseous ammonia source, an injector, first conduit and a second conduit. The injector may receive the liquid reductant from the reductant tank and the gaseous ammonia from the gaseous ammonia source and inject the liquid reductant into a stream of exhaust gas in a first mode, inject the gaseous ammonia into the stream of exhaust gas in a second mode, and both the liquid reductant and the gaseous ammonia into the stream of exhaust gas in a third mode. The first conduit may communicate liquid reductant from the reductant tank to the injector. The second conduit may communicate gaseous ammonia from the gaseous ammonia source to the injector.
