Mission Statement

To advise ARB staff on the technical issues associated with the retrofit of diesel PM controls on stationary, portable, and agricultural diesel engines.

Workgroup Objectives

  • To provide technical information regarding the diesel PM controls for stationary and portable engines, including agricultural engines.

  • To assist in developing specific demonstration projects for diesel-fueled stationary and portable engines that have not been successfully retrofitted.

  • To encourage catalyst-based diesel particulate filter manufacturers to participate in the verification and demonstration projects.

  • To assist in identifying unusual vehicle and/or engine operating modes that would present a technical challenge to catalyst-based diesel particulate filters effectiveness and durability.

  • To openly share test data from all demonstration programs, as well as, all non proprietary technical data.

  • To identify costs for retrofit devices.

  • To enhance communication between manufacturers of retrofit devices, engine and equipment manufacturers, and end-users regarding technical concerns and solutions.

  • To perform an advisory role in providing technical information regarding diesel PM controls.
