No EGR also means there is less to cool, which will help lower the cost of OEM integration," said Jim Fier, Cummins vice president, engineering. Cummins said its medium-duty, four-cyl- inder F3.8 and B4.5, and six-cylinder B6.7 and L9 engines offer significant performance im- provements over Stage IV/Tier 4 Final equiv- alent engines, with at least 10% more power and almost 20% more torque averaged across the range. Improvements to fuel efficiency will drop the overall fluids cost of the new Stage V engines by 3% on average depending on application, compared with those of Stage IV versions. Operating costs will be further re- duced with a 1,000-hour oil change interval, twice as long as the current 500 hours. Cum- mins' renamed, non-EGR X12 and X15 en- gines complete the company's current Stage V lineup, taking output up to 675 hp (503 kW) for heavy-duty applications. Start-stop technology is embedded in the engine management system, offer- ing the potential to realize fuel savings of 5%–15%, corresponding to the amount of equipment idle time. Cummins said the Stage V engines are enabled for wire- less connectivity to deliver instant en- gine diagnostics. Across the Stage V range, each engine re- quires only a single Cummins turbocharger. Wastegate turbocharging is used for the F3.8, B4.5 and L9 engines, and the B6.7 retains vari- able-geometry technology. The higher power Cummins Stage V engines use urea-SCR for NO x control, while the F3.8 utilizes an en- gine-mounted DPF without SCR. For both 4- and 6-cylinder engines, the in- crease in performance is applied across the full engine speed rpm range. This, said Cummins, makes the Stage V engines more adaptive for different machine-load demands, available either with high power at high engine rpm or high torque at low engine speed rpm. In order to simplify and improve the exhaust aftertreatment technology need- ed to meet Stage V, Cummins will combine DPF, SCR and urea-dosing technologies into what it calls its Single Module, provid- ing an up to 50% reduction in envelope size and a 30% reduction in weight compared with Stage IV exhaust aftertreatment. The company described the Single Module as essentially a "fit-and-forget sys- tem," capable of removing emissions al- most entirely by passive regeneration, with no impact on equipment operation and requiring no operator intervention. The service cleaning interval is expected to ex- tend significantly beyond the 5,000 hours of today's systems. The modular design of the Single Module allows for varying diam- eters and lengths, to efficiently match cat- alyst capacity to the power output of the engine. Cummins noted that its Stage V en- gines have a high degree of tolerance to sulphur in fuel — up to 5,000 parts per mil- lion — removing a major barrier in reach- ing the goal of a universal engine platform. This capability offers OEMs the pros- pect of using the same Cummins Stage V engine in their equipment worldwide, overcoming the complexity of multiple emissions regulations in effect. For each machine, that will bring a common engine installation, with the same electronic inte- gration and mechanical hookups, with or without exhaust aftertreatment, depend- ing on emissions levels.
