More Marine Upgrades From Tognum

Announcement of Tier 3 Series 4000 development comes on the heels of Tier 3 Series 2000

Posted on August 30, 2012

Tognum announced it has developed its MTU Series 4000 Ironmen workboat engines for compliance with U.S. EPA Tier 3 emissions regulations and the new engines will be available in the summer of 2013. As with the current Series 4000 generation, the new engines will be available in 8-, 12- or 16-cylinder configurations targeting mechanical and diesel-electric propulsion systems and marine generator sets.

When used as part of conventional mechanical drive systems, the Ironmen engines will be available in ratings from 560 to 2000 kW, while diesel-electric drives and marine gen-set engines will deliver 650 to 2000 kW outputs. No exhaust aftertreatment will be needed to meet the Tier 3 requirements, the company said, and the first versions will be available in mid-2013. The engines will be displayed for the first time at the International Workboat Show in New Orleans in December.

The 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 2 and ZKR 2 emissions regulations, Tognum said. The new-generation Series 4000 M64 engine will be EPA Tier 3 compliant using only in-engine technology and incorporates what Tognum called an optimized common rail fuel injection system, turbocharging and combustion processes. The engines are engineered to provide high fuel efficiency and maintenance intervals as long as 30 000 operating hours, the company said.

Tognum said the Ironmen engines are equipped with components needed for propulsion system packaging, such as pumps, coolers, filters and noise and vibration reducing engine mounts, allowing simpler installation. Typical workboat applications are tugs, offshore supply vessels, towboats, inland waterway vessels and displacement yachts.

The Series 4000 announcement comes just days after the company Tognum announced its development path for the MTU Series 2000 yacht engines for EPA Tier 3 recreational and IMO Tier 3 regulations. The new Series 2000 M96 engines will be able to cover outputs up to 1940 kW and comply with IMO Tier 2 and EPA Tier 3 regulations using in-engine technology only, the company said.

Compliance with IMO Tier 3 will be possible with selective catalytic reduction (SCR) aftertreatment, Tognum added. Despite the lower exhaust emissions, the manufacturer said that a reduction in fuel consumption will still be achieved. The new engines for pleasure craft compliant with EPA Tier 3 recreational will be available in 2014. Launch of the IMO Tier 3-compliant units will take place in early 2016.
