The Digest’s Multi-Slide Guide to Simultaneous GHG and Criteria Pollutants Reduction for Off-Road Powertrains

This project, 38% complete with $2.98M total funding, targets ≥10% GHG and ≥90% NOx reduction (<0.04 g/kW-hr) for off-road powertrains by 2025. Key future engine technologies include cylinder deactivation and high-efficiency turbochargers, showing preliminary 10% CO2 reduction. Multiple aftertreatment configurations (e.g., dual SCR, e-heater, fuel burner) are being explored. An incremental cost analysis reveals a -6.7% cost delta with all future options, making these technologies economically viable.
