Abstract
A fluid injector for injecting an injection fluid into a hot flow can include a flow structure defining an injection flow channel and configured to extend at least partially into a flow path to introduce the injection fluid into the hot flow in the flow path. The flow structure can include one or more heat resistance features to protect the flow structure and the fluid from heat of the hot flow.
Claims19
A fluid injector for injecting an injection fluid into a hot flow, comprising:
- a flow structure defining an injection flow channel and configured to extend at least partially into a flow path to introduce the injection fluid into the hot flow in the flow path, wherein the flow structure includes one or more heat resistance features to protect the flow structure and the fluid from heat of the hot flow.
The fluid injector 3, wherein the flow structure includes a base, a stem extending from the base, and an injector head at a distal end of the stem.
A selective catalytic reaction (SCR) system, comprising:
- a diesel exhaust fuel (DEF) injector configured to receive diesel fuel to cool the diesel exhaust fluid injector.
A method, comprising:
- injecting diesel exhaust fluid (DEF) into a diesel exhaust from a center of a diesel exhaust channel using an injector.
