Solenoids at Work in SCR Systems

Diesel engine manufacturers are utilizing Selective Catalytic Reduction (SCR) technology to meet more stringent emissions regulations. These SCR systems use diesel exhaust fluid, better known as AdBlue®, injected into the exhaust stream to create a chemical composition that changes the exhaust into a mixture of nitrogen and oxygen.
