MTU Asia has unveiled new engines to meet the demands of EU Stage IV and EPA Tier 4 and EU Stage III B and EPA Tier 4i (interim) legislation.

The new engines, which were shown for the first time in the iron at this week's bauma China 2010, cover drives up to 730 kW for US EPA Tier 4 (from 2014), and below 560 kW for European Union (EU) Stage III B and EPA Tier 4 interim (from 2011) and include MTU's Series 400, 500, 900, 2000 and 4000 engines producing between 100 and 3000 kW.

New engines up to 730 kW will meet EPA Tier 4 requirements using exhaust gas recirculation and do not need diesel particulate filters or SCR units. To meet the emission limits MTU placed particular emphasis on optimizing the combustion process. This, said the company, is the only way of minimizing the outlay necessary for exhaust gas after-treatment.

"Overall," said MTU Asia's president and CEO Peter Kneipp, "the customer benefits from an integrated system with low conversion and operating costs."

For EU Stage III B and EPA Tier 4i, which come into force from 2011, MTU will supply engines up to 560 kW with an integrated SCR unit. This technology, said the company, was selected in cooperation with its major customers and allows OEMs to convert their vehicles and equipment for 2011 emissions targets "with the least possible outlay".

This approach, it added, also brings additional benefits in the form of reduced fuel consumption.

Legislative requirements mean further development of Series 2000 and Series 4000 to comply with EPA Tier 4 interim and Tier 4 final is primarily aimed at the US market.

Mr Kneipp told International Construction the new engines were designed for use in port equipment - dockside cranes, container stackers, mobile cranes - and the mining sector - haul trucks, wheeled loaders, excavators.

It is expected that the new engines will be targeted at manufacturers in China looking to export their construction equipment rather than sell it into the domestic market.
