EquipmentWorld.com | May 2017 39 ConExpo engine roundup | by Tom Jackson | TJackson@randallreilly.com Engine manufacturers at ConExpo bring us some good news for a change NEXT GEN DIESELS: D uring the past two decades, engine manufacturers poured billions of dollars into developing diesel engines that meet the government's strict exhaust emissions limits. All that money and manpower went into solving a problem created by government regulations. Now that the Tier 4 Final emission reduction technology is settled, engine OEMs have turned their focus toward making these engines better, not just cleaner. These new engines have smaller footprints, less complexity, extended service intervals and increased power density. Here are some examples from ConExpo that show how this new generation of engines will do more for the end user. B etween now and 2020, you'll hear a lot about Stage V engines. Stage V is a European regulation designed to reduce the number of ultra-small soot particles in diesel engine exhaust. But not to worry. The technology needed to meet Stage V emissions levels is not as complex or expensive as the technology that took the industry from Tier 3 to Tier 4 Final. In fact, many smaller engines already meet the standard. To get the remaining engines up to snuff only requires a more effi cient particu- late fi lter, which will be an inexpensive, plug- and-play change. So far, there is no indication that the U. S. Environmental Protec- tion Agency will require diesel engines in this country to meet the same spec. But since engines are a global product, most OEMs say they'll build the same engine for U.S. and European markets, and when needed for the European market, just bolt on the more effi cient diesel particu- late fi lter. What is a Stage V engine? D uring the past two decades, engine manufacturers poured billions of dollars Cummins Stage V engines include more power and torque, lighter weight and smaller footprints, plus a reduction in diesel and DEF consumption.
