MTU’s latest version of the series 4000 Ironmen engine

Tognum has announced that its MTU subsidiary is to launch an enhanced version of the series 4000 Ironmen engines which will comply with US EPA Tier 3 emissions regulations, using only internal emission control methods.

As with the current generation, the new series 4000 engines will be available with 8, 12, or 16 cylinders for use in diesel-mechanical and diesel-electric propulsion systems or for powering onboard gensets. Installed in diesel-mechanical systems, the Ironmen engines will be able to cover power requirements from 750bhp to 2,680bhp, while diesel-electric drives and marine gensets will deliver 650kW to 2,000 kW power output. No exhaust gas aftertreatment will be needed and the first engines will be available in mid-2013.

This latest version of the Ironmen engines is based on the current MTU Series 4000 M63 long-stroke engine, which meets EPA Tier 2, IMO Tier II and ZKR II emissions regulations. The new-generation Series 4000 M64 engine features optimised common rail fuel injection, turbocharging and combustion processes. Despite the low emissions levels, MTU says the engines will boast high fuel efficiency and maintenance intervals as long as 30,000 operating hours. They will be supplied with all ancillary components, including pumps, coolers, filters and resilient mounts.
