Description Of Change: Improved diesel oxidation catalyst (DOC) is used on certain M313D and M315D Wheeled Excavators that are equipped with the Tier 4 Interim/Stage 3b aftertreatment system.

Changes have been made to the production process of the DOC, to improve performance and durability. These improvements result in better conversion rates of injected hydrocarbon (HC). Better conversion rates of injected HC result in sufficient operating temperatures necessary for consistent diesel particulate filter (DPF) regeneration. Consistent DPF regeneration contributes to improved performance and durability of the machine.
