Exhaust Aftertreatment


Global regulation of emission pollutants from the engine exhausts are becoming increasingly stringent. The Selective Catalytic Reduction (SCR) system is one of the exhaust after-treatment systems adopted by vehicle and engine manufacturers to reduce emissions pollutants such as NOx (generic term for NO, nitric oxide, and NO2, nitrogen dioxide) from the engine exhaust gas.

Diesel Exhaust Fluid (DEF), or AdBlue, is a 32.5% urea-in-water solution that is injected into the SCR system to convert NOx into harmless H2O and N2.

As the world’s leading manufacturer of DEF/AdBlue level senders, KUS products are designed and manufactured to ISO 22241 standards, and are widely used in SCR systems for on-road and off-road vehicles worldwide.
