The term coined by mechanical officers as “souping” is when locomotives spend several hours a day idling causing the engine lube oil to push out and coat the interior of the stack. Souping is messy, creates safety hazards, and causes hot embers to be blown into the air when shifting to higher notches.
In order to reduce this issue, Interstate-McBee designed an injector specifically for extended idle applications. These extended idle injectors feature a helix cut plunger design that allows for modified fuel delivery at lower level notches for more efficient fuel burn while also providing full fuel at higher notches. Extended idle injectors also feature our patented ECOTIP® Superstack that reduces smoke and provides more efficient fuel atomization.
Benefits of extended idle injectors:
- Decreased risk of trackside fire
- Diminished chance of fines
- Reduced oil on car bodies
- Less cleaning
- Lower labor costs
- Safer work environment
- Reduce ring and liner wear
- Accommodates both light and heavy loads
- Increase overall locomotive performance
