EPA Verification

California ARB Verification
 

Today’s diesel engines are designed to produce up to 90% fewer harmful emissions.  But, there are a large number of older engines still in operation emitting hydrocarbons, particulate matter, oxides of nitrogen and carbon monoxide.

Cummins Emission Solutions has the knowledge and expertise to help you chose the right retrofit aftertreatment technology for the following applications:

  • School Bus
  • Transit Bus
  • Municipal Fleets
  • On-highway Truck
  • Construction Equipment
  • Port Equipment
  • Mining Equipment
  • Fracing Rigs
  • Gas Compression
  • Rail
  • Workover

As the world’s most experienced provider of diesel emissions control (with over 2.0 million units in operation and 30 years in exhaust product development and manufacturing), Cummins Emission Solutions has the expertise to help you chose the right emissions product for your application based on local air quality laws and regulations.  We can also help identify funding and incentive opportunities that apply in your region.
 

Choosing the Right Retrofit Solutions
To identify the best product to fit your need, your Cummins Emission Solutions representative will help you with answers to the following questions:

  • What does Particulate Matter or NOx reduction mean?
  • Is PM or NOx reduction required?
  • What funding sources are available?
  • Is verification (EPA or CARB) required to qualify for funding?
  • What type of fuel is required and available?
  • What is the duty cycle of the engine, and what are the operating temperatures?
  • How old is the engine and to what emissions standard was it built?

Based upon this information, Cummins Emission Solutions can make the appropriate product recommendation.
 

Products By Emissions Goal
Our approach to engine aftertreatment is based not only on best-in-class technology and design, but also on providing a product and cost that align with customer requirements. The percentage and type of exhaust emission reductions that are needed, determine which Cummins Emission Solutions aftertreatment products are best suited for your operation.
