Research on SSCR Technology to Reduce NOx Emissions for Diesel Engines

Mainly due to the current reduction of NOx that is SCR technology which has some problems, it is difficult to meet the increasingly stringent emission regulations.Then people study the SSCR system that uses solid reducing agent, the solid reducing agent has large ammonia density.SSCR system injects NH3 directly into the tail in the airway through the injection system ,which is directly mixing with the exhaust. Comparing with SCR system,the decomposition temperature is low,the mixing time is shorter,that also reduces the negative impact caused by injection.
