The latest generation of MTU’s Series 4000 marine engines combined with MTU’s new SCR system for IMO III and EPA Tier IV are designed for flexible installation and feature an excellent power-to-weight ratio. NOx emissions have been reduced by 75% compared with IMO II and particulate emissions by 65% compared with EPA Tier 3. For yachts and patrol boats the engines are currently available from MTU as 12, 16 and 20-cylinder versions for a power range extending from 2,160 to 3,900 kW.

For work boats such as tug boats and ferries, MTU will gradually be introducing the engines onto the market as 12, 16 and 20-cylinder versions covering a power range from 1,119 to 3,220 kW. The work boat engines will offer a 45 per cent increase in output compared with the predecessor versions. It was also possible to reduce fuel consumption by a further 5 per cent. MTU has already delivered the first EPA Tier 4 compliant propulsion systems for new catamarans in California.
