EPA Emission Requirement Tier 4

• Tier 4 applicable for engines built after January 1st 2011

NTP is expected at the earliest in July 2010; too late to order Tier 3 engines

• Tier 4 implications on vehicle:

- Larger engine cooling equipment- Particulate filter in exhaust pipe- SCR equipment and urea tank to eliminate NOx emissions.

• Tier 4 is applicable to FRA and non-FRA compliant DMUs

• Expected engine replacement in 2020.

Replacement engines will have to be Tier 4 compliant. This means the DMUs would have to be substantially upgraded at that time after only 5 to 6 years in service.
