Tier 3 compliance at the WorkBoat Show

The upgraded MTU 8V 4000 M54 Ironmen workboat engine is claimed to be the first US EPA Tier 3 compliant engine in its class. Designed to meet Tier 3 without exhaust after-treatment, the engines will be available in 2013 with 8, 12 or 16 cylinders for use in diesel-mechanical and diesel-electric propulsion systems or for powering on board gensets. Installed in diesel-mechanical systems, the Ironmen engines will be able to meet power requirements from 560 kW to 2,000 kW, while diesel-electric drives and marine gensets will deliver 650 kW to 2,000 kW power output.

Other MTU commercial marine products on show in New Orleans included the 16V 2000 M61 engine and the MTU 12V4000 M24 diesel electric package.
