Summary

The more stringent emission limits specified by EPA Tier 4 interim – 3.5 g/kWh NOx and 0.1 g/kWh particulate – have applied to engines for off-highway applications with a rated power of more than 560 kW since January 2011. In order to comply with this emission standard, the previous Series 2000 PLN (Pump Line Nozzle) engines for C&I and O&G applications have been superseded by a new design. Features of this new series, consisting of 12V and 16V engines, include common-rail injection, an EGR combustion system based on the dispensing-cylinder concept, and compact, 2-stage, regulated turbocharging. The newly developed, map-controlled wastegate and the new Series ZR125 exhaust turbocharger are being used here for the first time. Specific customer requirements for industrial engines – such as robust design, application options and engine performance map width – have been met rigorously. Despite the more stringent emission limits, the new engine has a wider application range and lower fuel consumption than its predecessor.
