Which is better – SCR or EGR?

At present, it is simply not possible to offer a conclusive recommendation for either technology. The fact is that any attempt to reduce harmful emissions costs money. Further product development is necessary to both meet exhaust emissions standards and still maintain a high engine output. What’s more, both technologies are suitable when it comes to reducing emissions. Unfortunately, however, it is not possible to offer any reliable or conclusive information regarding the exact costs and fuel consumption rates of these technologies at present. SCR is regarded as a solution for high-power agricultural machinery. Suppliers opting for this system can be assured of significant fuel savings. One manufacturer in particular even goes so far as to claim that savings made through reduced diesel fuel consumption would compensate for any financial outlay accompanying the new consumables required, such as AdBlue®. There can be no certainty of this, however. SCR technology would probably be more profitable for farms employing large vehicle fleets, since the technology would require, amongst other things, the installation of a tank facility for AdBlue® on the farm.

In the case of EGR technology, the outlay is much lower, and, most importantly, there are fewer follow-up costs. This solution is arguably better suited to smaller farms. However, EGR technology places a greater burden on the engine, which, in turn, can negatively impact on fuel consumption. At this stage, no one can be sure of exactly how much fuel consumption will be affected by either system. What is clear, however, is that there is more to an agricultural machine than just its engine. It always comes down to the system as a whole – what we call “Kraftintelligenz”.

CLAAS can do both: SCR or EGR (with DPF*).

The use of SCR and EGR technologies continues to attract much debate in the industry. The first three legislative exhaust emissions stages have proven effective in cutting pollutant emissions. A secondary effect, however, has been the increased complexity, heat generation and fuel consumption of engines. This is because the entire purification process took place within the engine itself. Now, the industry is entering a new phase. Stage IIIb will lead to two technological variants in agricultural machines: selective catalytic converter (SCR) and exhaust gas recirculation (EGR) technology.

Many manufacturers in the agricultural industry have had to commit to a single technology, because they integrate their own engine systems. CLAAS, however, has much greater flexibility in this respect. We are the only manufacturer that hasn’t had to make such a call. We utilise both SCR and EGR technologies. The choice of system depends on the engine make and drive technology we use in each model. This gives our customers the choice, and they can expect the very best advice, service and quality either way.
