MTU announced that it will debut its newest Series 2000 marine engine at the Yacht & Brokerage Show in Miami, Florida, U.S.A. this month. The latest version of the engine – the M94 – includes an improved power-to-weight ratio. Power has been increased by 8% and the output range is now 1193 up to 1939 kW at 2450 r/min. This was achieved with changes in turbocharging, fuel injection and engine control. The M94 will be available to customers in 10 and 12-cylinder configurations beginning in March, with the 16-cylinder to follow in May. An eight-cylinder configuration will follow within this year.
Turbocharger selection was optimized for fuel consumption at cruise speed and its ability to generate higher boost pressure at lower engine speeds. This is one of the major advances for a reduction of a vessel’s acceleration time. The engines not only conform to worldwide emissions standards, including EPA Tier 2 commercial and IMO, but also comes standard with SOLAS (Safety of Life at Sea) certification. It features double wall fuel lines and triple wall water cooled turbocharger and exhaust routings that keep the engine surface temperature under 220° Celsius.
