Rate Shaping Nozzle
Stanadyne has developed the RSN feature to assist engine manufacturers meet the increasingly stringent emissions standards, achieve combustion noise reductions and improve low speed light load stability. The RSN incorporates an innovative and cost competitive approach to fuel injection rate shaping. This feature can be incorporated into either Stanadyne's Pencil Nozzle or conventional size injectors.
Features & Capabilities
  • Production proven engine emissions, combustion noise reduction and low speed light load stability
  • Greater injection rate control potential than the industry common two spring (TSI) approach
  • Physically interchangeable with current injector size and application configurations
  • More stable performance over the life of the product than the TSI due to its non-contact operation
  • More uniform spray characteristics due to the lower guide feature
