I cannot provide a definitive answer to the question "What year did DEF start on Cummins?" because the implementation of DEF (Diesel Exhaust Fluid) in Cummins engines wasn't a single, universal event. The introduction of DEF systems in Cummins engines depended on several factors, including:

• Engine Model: Different Cummins engine models were equipped with DEF systems at different times. Larger, heavier-duty engines were often among the first to adopt the technology due to stricter emission regulations. Smaller, lighter-duty engines followed later.
• Emission Regulations: The timing of DEF implementation was heavily influenced by evolving emission standards (like EPA regulations in the US or Euro standards in Europe). As regulations tightened, the need for DEF to reduce NOx emissions increased.
• Geographical Location: The adoption of DEF varied by region due to differing emission regulations and market demands.

Instead of a single year, it's more accurate to say that Cummins began incorporating DEF systems into their engines gradually, starting in the mid-2000s and continuing to the present day. To find out exactly when a specific Cummins engine model started using DEF, you'd need to consult:

• Cummins' official documentation: Their website and technical manuals contain detailed specifications for each engine model, including information on emission systems.
• The engine's identification plate: This plate usually provides the engine model number and other vital information. You can then use that number to look up the specifications.
• A Cummins dealer or service center: They have access to the most up-to-date information and can definitively tell you if a specific engine uses DEF and when it was introduced.

In short, there's no single year for the start of DEF in Cummins engines. It was a phased rollout across their various engine models, driven by evolving emission regulations. To find the specific year for your engine, refer to the resources listed above.
