11,111 MTU ENGINES FROM ROLLS-ROYCE FOR FINNISH MANUFACTURER OF FORESTRY MACHINES PONSSE

Nov 13, 2017

  • Ponsse has put its trust in MTU engines for more than 15 years
  • Stage V engine has now completed intensive field testing

FRIEDRICHSHAFEN – The 11,111th engine delivered to Ponsse by Rolls-Royce is a Series 1000 six-cylinder in-line engine from MTU. This unit will soon be used to deliver power to a Scorpion, the most advanced full harvester, produced by the world’s leading manufacturer of forestry machines.

The delivery of 11,111 engines represents a period of more than 15 years, throughout which Ponsse has put its trust in the reliability of the engines delivered by its exclusive supplier MTU.

“Our products occupy the premium segment in the market for wood harvesting equipment and are recognised throughout the world for their operational efficiency and durability,” said Dr. Juha Inberg, Director Technology and R&D at Ponsse plc.

The demands placed on the engines are correspondingly high. They are required to complete 4,000 to 6,000 hours of operation every year – and must do that under the most adverse operating conditions, on tough terrain and under extreme cold and heat. The drive systems based on Mercedes-Benz truck engines have been optimised by MTU for off-highway requirements.

Since January 2017, Ponsse has also been testing one of the first of the Stage V generation 6R 1000 engines under these conditions. Installed in an Ergo harvester, it has undergone a thorough test programme. After the successful completion of the tests, Ponsse placed an order for a further five Stage V engines, two 4R 1000s and four 6R 1000s.

Stage V engine has already completed more than 1,000 hours of operation
The new engines in non-road mobile agricultural machinery and other off-highway applications, will have to meet the much tougher Stage V emission regulations as of 2019. MTU’s 6R 1000 engine has already completed more than 1,000 hours of operation in an Ergo harvester to Ponsse’s complete satisfaction and has done so in freezing temperatures, which in some cases dropped below minus 30°C. “This experience is very important for the ‘Stage V engines’ development programme, because we are able to demonstrate the functionality, reliability and durability of the engine under extremely difficult conditions. We can also identify if any improvements may need to be made long before series production starts,” said Stefan Rudert, Head of Application Engineering for Construction and Agriculture at MTU.

The power outputs of the six-cylinder MTU Series 1100 and 1500 engines have been boosted by 20 kW across the board, meaning they now cover a power range of 240 to 480 kW and deliver up to 3,100 Nm of torque. The further developed engines will also receive EPA Tier 4 certification, enabling vehicle manufacturers to target both the EU and NAFTA markets, with both regions able to benefit from the product improvements.

Since January 2017, the Finnish manufacturer of forestry machines Ponsse has been testing an MTU 6R 1000 engine system in an Ergo full harvester. After the engine had completed 750 hours of operation under what in some cases were extreme operating conditions, with temperatures below -30°C, to Ponsse’s complete satisfaction, an agreement has now been reached to install a further five MTU field test engines meeting EU Stage V requirements in Ponsse forest machines.
