One of the reasons KUS is the go-to choice for engineers and designers in OEM operations across the globe is our commitment to maintaining the highest quality control standards possible. KUS has a reputation for providing reliable products, helpful technical support, and attentive service to our customers all over the world.

Exhaust Aftertreatment


Global emission regulations on diesel engine vehicles are becoming increasingly stringent. In the U.S., all heavy and medium duty diesel truck engines produced after January 1, 2010 must meet the latest EPA emission standards. Vehicle manufacturers accomplish this through the use of an aftertreatment system. A selective catalytic reduction (SCR) system is an aftertreatment option that uses diesel exhaust fluid (DEF), or AdBlue, to reduce harmful emissions.

KUS works with global exhaust aftertreatment system integrators — and vehicle and engine OEMs — to design and manufacture components for the SCR system.

Our DEF products focus on NOx conversion and we build them in accordance with ISO 22241 standards. They include DEF tanks, DEF level sensors, DEF nozzles, DEF tank caps, and other accessories. KUS manufactures and assembles the whole DEF tank assembly in-house. Our components are widely used in SCR systems for on-road and off-road vehicles worldwide.
