New 8-cylinder engine launched

Tognum company MTU Friedrichshafen has introduced an 8-cylinder workboat version of its Series 4000 engine at the Europort exhibition in Rotterdam.

The long-stroke engine from the “Iron Men” range has been specially optimized to meet the needs of workboats. Specific consumption has been reduced to 195 grams per kilowatt hour and maintenance intervals for major overhauls have been extended to up to 34,000 hours, depending on output and load profile. The Series 4000 now offers configurations with 8, 12 and 16 cylinders for the 746KW to 2,240 kW power range (1,000 to 3,000 bhp).

The new engine meets all current emission requirements such as EPA Tier 2, CCNR 2 and EU Stage IIIA, and is designed for compliance with emissions regulations expected in the future.

MTU says that vessels such as ocean-going tugs, inland waterway vessels and fireboats are the workhorses of the workboat world. The use of diesel engines in workboats varies enormously depending on the type of ship. Different applications impose different demands on the engine. Inland waterway vessels which operate day and night need quite a different type of engine from a mega-yacht, for example. The claimed key features of the “Iron Men” Series 4000 engines for workboats are lowest possible fuel consumption, long maintenance intervals for minimum service life costs, and maximum availability and reliability.
