Abstract

A liquid cooled reduction unit includes a diesel exhaust fluid (DEF) injection valve. The valve includes an end portion extending to a distal end. The valve is configured to receive a DEF and force the DEF to exit at the distal end such that the DEF is then directed and applied to an exhaust stream of a vehicle engine. A coolant jacket is selectively filled with a coolant and has an outer side and an inner side. The inner side of the jacket faces a length of the end portion and is separated from the length of the end portion by an air gap.
