Workboat Engine MTU Series 4000 Upgrade by Tognum

Tognum to make upgraded MTU Series 4000 workboat engines available summer 2013. Tognum will enhance its MTU Series 4000 Ironmen workboat engines for compliance with US EPA Tier 3 emissions regulations.
This latest version of the Ironmen engines is based on today’s proven MTU Series 4000 M63 long-stroke engine, which meets EPA Tier 2, IMO Tier 2 and ZKR II emissions regulations. The new generation Series 4000 M64 engine will be EPA Tier 3-compliant using only in-engine technology, and features optimization of MTU’s renowned common rail fuel injection system, turbocharging and combustion processes.
As with the current generation, these 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 on-board gensets.
Installed in diesel-mechanical systems, the Ironmen engines will be able to cover power requirements from 750 to 2,680 bhp (560 to 2,000 kW), while diesel-electric drives and marine gensets will deliver 650 to 2,000 kW power output. No exhaust gas aftertreatment will be needed and the first engines will be available in mid-2013. The engines will be displayed for the first time at the International Workboat Show, booth No. 2601, in New Orleans, Dec. 5-7, 2012.
