Looking at both options, we can conclude that even if SCR improves fuel economy and if urea costs come down at some point, then the additional costs of training service techs, storing and purchasing replacement parts for the urea system, and adding a urea infrastructure to your business will add unfamiliarity and costs that are not good for your bottom line.Thomas Built Buses counters with a Web site about its SCR solution. The company breaks the choice down to a top ten list:
1. Best fuel efficiencyTake a look at both sites for yourself. Let us know what you think. What questions do you still have about SCR and EGR? Let us know and we'll see if we can get them answered for you. Are you ready to make a switch? Have you already committed?
2. Proven technology in Europe
3. EPA recommended and approved
4. Higher engine power density
5. No increased heat rejection, allowing for more efficient combustion
6. Lower cost of total ownership
9. Easy to service
