questions to ask about aftertreatment

Clearing the Air on Emissions

Get the Facts about Factors that Affect Durability

The latest emissions standards are driving the use of aftertreatment systems like Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR). Both are sensitive to fuels, environmental conditions and duty cycles — and that means engine manufacturers must pay extra attention to durability to ensure these systems can stand up to tough environments and applications. As you’re talking with different engine suppliers about their products, here are four key questions about aftertreatment you’ll want to ask.


1. Have you done testing in my application?

2. Is there a minimum duty or load factor required?

3. What are your installation guidelines?

4. How transparent is your regeneration?

Getting the facts about validation, load requirements, installation guidelines and transparency will help you choose the most durable engine option for your products.
