I DA U N I V E R S A L N ove m b e r - D e ce m b e r 2 0 1 6 67 Bernd Krüper, head of construction and agriculture business at MTU, said, "Construction companies will benefi t immediately from the advanced technological developments for Stage V. "What we expect to see from the development work is higher torque at low rpm, a further reduction in fuel consumption and an extended power range compared with predecessor engines." He added that with this development, the company was building on previous Series 1000 to 1500 diesel engines designed to meet Stage IV and EPA Tier 4 fi nal, which he said were well-established in the market. The engines will be available in the 100 to 480kW power range. MTU has also launched its new Emission Flex Package, which enables customers to operate engines in countries where very different emission requirements apply, and fuels are used that have a high sulfur content. Using software designed specifi cally for the purpose, the engine's exhaust gas after-treatment system and selec- tive catalytic reduction (SCR) system can be deactivated. Krüper said, "Before the implementation and sale of this solution to our customers, we conclude a contract, the terms of which ensure that the engines comply with the emission regulations in the respective countries." MTU operates further afi eld, too, and has recently agreed to a deal with China Yuchai International's main operating subsidiary, Guangxi Yuchai Machinery Company (GYMCL), to set up a 50:50 joint venture for the produc- tion of MTU diesel engines in China. Each party will invest RMB75 million ( 10.43 million) in the joint venture. Meanwhile, Perkins has launched a new family of four- cylinder, 2.8 and 3.6 liter diesel engines. The new Syncro range delivers between 45 and 100kW, and claims to meet multiple global emissions standards including Stage V and Tier 4 Final. The company said the new 2.8 and 3.6 liter engines deliver the perfor- mance, value and reliability its customers expected, to help them access new markets and support their business growth. It also said that the high power and torque density will give Original Equipment Manufacturers (OEMs) the opportunity to move to smaller, more compact engines. The 3.6 liter engine promises an improved fuel economy of eight percent and power up to 100kW, while the 2.8 liter engine reportedly delivers a maximum of 55kW. Allister Dennis, product manager at Perkins, said, "The recent advances in fuel systems, control systems, predic- tive engineering and after treatment ensures our new 2.8 and 3.6 liter engines are the right solution for off-highway machines, like wheeled loaders, tractors, telehandlers and excavators. "We've now started work on this family of engines to give us and our customers plenty of develop- ment and fi eld validation time before Stage V introduction." Cummins Cummins has recently launched its new F3.8, B4.5, B6.7 and L9 engines, which it said were designed to meet Stage V emissions regulations. The new engines range from 75 to 321kW, and claim major increases in power and torque by removing the exhaust gas recirculation (EGR) system, and using Cummins' single module after-treat- ment technology. Chairman and CEO Tom Linebarger said, "Cummins is raising the engine performance bar higher with our EGR-free approach for Stage V, and that leadership will continue to drive the equipment industry forward to meet the regulations in 2019 with simpler machine integration. He added, "The engines we unveiled have been designed from the outset to reduce Stage V cost of ownership to levels equivalent to that of engines meeting emissions regulations as far back as 10 years ago. "This achievement is the result of product development inspired more than ever by the needs of our customers, rather than by just meeting emissions regulations, however stringent they may be." Compared to Cummins' Stage IV and Tier 4 Final engines, power output for the new 3.8 to 9 liter engines for Stage V is said to have increased by over 10 percent on average. Meanwhile, the company has introduced its Connected Diagnostics technology, meaning its equipment can now wirelessly connect the engine to Cummins for immediate diagnosis of an engine system fault alert, and have valuable information delivered back to the customer within seconds. Deutz German-based manufacturer Deutz, meanwhile, has launched its new TCD 2.2 diesel and gas engine. This 2.2 liter engine is a three-cylinder variant of Deutz's TCD 2.9 four-cylinder engine. The TCD 2.2, with a rating of up to 55kW, is said to be particularly suitable for applications in material handling and compact construction equipment. The engine will be available in both a diesel and a lique- fi ed petroleum gas (LPG) variant. The gas variant is said to produce up to 42kW and is a fi rst within Deutz's otherwise diesel-only product range. The TCD 2.2 will go into series production in 2019 when the Stage V emissions standards Continued on page 56
