That's up to the EPA, but if Europe is any indication it won't be a big deal. One thing that clearly stood out at the In- termat trade show this spring is that the diesel engine emissions saga isn't over yet. (See a brief his- tory of emissions regulations on page 52) The good news is the next round of engine emis- sions regulations are going to be easy to meet, and they're not due for some time. "The engine industry is generally happy with the dates and regulations," said Richard Payne, Cummins off-highway regulatory affairs director for Europe. Regulators in Europe are zeroing in on 2019/2020 for their next step in emissions restrictions, what they call Stage V. Since the engine business is global, European regulations closely parallel those in the United States to prevent OEMs from having to make a different engine for every market. The only major difference is in nomenclature. European Stage If Europe is any indicator, it shouldn't be a problem Are you ready for Tier 5 emissions regulations? Cummins EcoFit The Cummins EcoFit Single Module, is a "single can" design, combining a DPF, DOC and SCR in one unit. It is up to 60 percent smaller and 40 percent lighter and has 20 percent less backpressure compared to today's combined SCR and DPF systems. Cummins says the EcoFit can be easily adapted to Tier 5 or Stage V regulations. Perkins 404F-E22TA Perkins new 400 series engines upgrade the line with common rail direct injection and full authority electronics. These enhancements allow OEMs greater fl exibility in tailoring the engine to specifi c applica- tions and get equivalent horsepower and improved fuel economy in an engine with a smaller footprint.
