Kelas—the indispensable part for vehicles in State IV times
Time:2011-03-25   view:   author:kelas

The implementation of state IV standard means the emission controlling of vehicle exhaust gas must adopt more advanced technology. At present, the SCR technology is the state IV emission solution which is best suitable for heavy-duty trucks and buses. But this technology must use urea solution to deal with the nitrogen oxide of exhaust gas. Thus, the qualified vehicle urea solution—KLS becomes the indispensable product for the heavy-duty trucks and buses to reach the state IV emission standard.
To prepare for the forthcoming state IV standard, many finished automobile and engine manufacturers have positively research, develop and produce the engines which conform to the state IV standard. The KLS developed by our company solved the problem of new engines can’t find the suitable vehicle urea solution after adopting the SCR technology. It can be said that it has removed many problems for the finished automobile and engine manufacturers.
The constantly upgrading vehicle emission standard which gradually integrates with the international developing countries will realize a stable improvement for the air quality in the next few years in China.With the KLS and other emerging high-tech products, the fresh air will no longer be the dream of the Chinese.
