Getting Inside Selective Catalytic Reduction
Using an actual Selective Catalytic Reduction (SCR) muffler that’s been cut away to reveal its inner workings, Kevin Knapp from Case IH explains the SCR system that can be found in our new Tier 4A 30 Series Axial-Flow combines, as well as our high-horsepower tractors. The system is a model of simplicity and engineering efficiency.
The biggest advantage of SCR as the emissions-reduction technology of choice is what you don’t see. The entire system can be explained without showing the engine at all. That’s because Tier 4 compliance is achieved after combustion, allowing the power plant to be tuned for optimum performance and economy. Kevin probably puts it best when he says, “The engine’s just there to create power, and do it efficiently.”
