Nitrogen oxides (Nox), unhealthy substances found in the emissions of diesel-powered vehicles, can be reduced with the help of urea solutions like AdBlue® for example. During the so-called exhaust gas treatment, the urea solution is fed into the exhaust system of diesel automobiles and trucks. With high temperature endoscopes from SCHÖLLY, this injection process can be observed and any potential for optimization can be discovered.
The correct dosage of AdBlue must be adjusted to the nitrogen oxide emission of the individual engine type. For this reason researchers and developers of exhaust systems are carefully examining the injection process of AdBlue. If the dosage is too low, the legally required emission levels will not be reached. But too much of the urea solution leads to deposits and blockage of the SCR catalytic converter, in which the catalytic reduction of the nitrogen oxides takes place. With high temperature endoscopes from SCHÖLLY, the injection process, the distribution of the urea solution, as well as the reduction of urea deposits can be analyzed and optimized under different temperature and operational conditions.
High temperature endoscopes from SCHÖLLY are customer-specific endoscopes which display high heat resistance, thanks to special technologies and cooling functions. They deliver reliable inspection results at temperatures of up to 2.000 °C. Heat resistant endoscopes from SCHÖLLY are used not only in the automotive industry, but also in the fields of glass and metal, energy production and the food industry. The company has gained comprehensive expertise over the years in high temperature applications.
Example of a high temperature endoscope in extreme ambiance, here being used at an energy utilization plant.
In the automotive industry, SCHÖLLY has already implemented solutions at well-known automotive and truck manufacturers as well as their suppliers. In addition to rigid high temperature endoscopes, the company also develops special flexible endoscopes for lower temperature ranges and inspection areas that are difficult to access.
