EGRT Retrofit
• Relatively high NOx reduction (> 40%) achievable in a retrofit system
• >90% CO, HC and PM reduction achievable
• Proven durability, over 1200 on-road; OE approved
• Engine mapping required for new engine models; Map development “key” to avoid DPF plugging
• Commercialization and CARB/EPA Verification in process
• Work with engine OE to maintain engine warranty
• JM provide training/support in co-operation with the engine OE
