MTU Series 1000, 1100, 1300 and 1500 engines have been awarded their EU Stage V compliance certificates from the German Federal Motor Vehicle Authority (“KBA”). The engines have been specially designed for industrial applications in the agricultural and construction sectors and are based on commercial vehicle engines from Daimler. They cover the 115 to 480 kW power range.
Detailed post-trial inspections and prototype testing
The first Stage V engines were put through tough trials in what were often extreme weather conditions and altitudes, and were subjected to systematic forensic testing in collaboration with Daimler between July and November 2017. The engines currently running have now notched up a total of 26,000 operating hours, with the longest-running unit on the go for a full 4,200 hours.
Dr. Aaron Haußmann, Head of Construction & Agriculture Sales at MTU, said: “We’ve collated and analyzed a whole host of usage data and operating experience from our customers, all aimed at achieving the best possible result. The Series 1000, 1100, 1300 and 1500 are now officially certified to Stage V, enabling our customers to prepare for the new emissions requirements by taking delivery of full-production engines.”
Design improvements using DPFs and SCR systems
The new EU Stage V standard comprises what are so far the most stringent levels for particulate and nitrous oxide emissions given off by mobile machinery. MTU is meeting these strict requirements by means of in-engine design enhancements, and by adding an SCR system and an extra diesel particulate filter.
The EU Stage V engines are going into series production and will be available to customers from June 2018, a full seven months before the new directive goes onto the statute books. Customers will continue to be able to source the EU Stage IV engines which will be available alongside the new models.
