MAN Engines Debuting Two New Marine Engines
By Jack Burke05 September 2018
MAN Engines is debuting the V12-2000 and V8-1300 marine engines at the 2018 Cannes Yachting Festival.
The 24L, V-engine is the only 12-cylinder to offer 2000 hp (1471 kW), MAN Engine said. Likewise, the strongest V8 engine for yachts and sport fishing boats on the market is the newly introduced V8-1300, which offers 1300 hp (956 kW) from 16L of displacement.
Both the V12-2000 and V8-1300 engines offer power densities of 61 kW and 59 kW respectively per liter of displacement. When compared to similar powerful engines with larger displacement and more cylinders, the minimal space requirement and low weight are a clear advantage in terms of ship design, MAN Engines said.
The new engines retain the compact installation dimensions of the V12-1900 and the V8-1200 – the formerly highest power levels. These dimensions are 2159 x 1153 x 1272 mm (length x width x height) for the V12-2000, and 1736 x 1153 x 1222 mm (length x width x height) for the V8-1300. The dry weights of 2,380 kg (V12-2000) and 1,880 kg (V8-1300) have also remained the same; through a power increase of both engines, this also contributes to a noticeably better power to weight ratio of 1.62 kg/kW for the V12-2000, and 1.96 kg/kW for the V8-1300, MAN Engines said.
“With the V12-2000 and the V8-1300 we have set a new benchmark for performance and compactness,” said Claus Benzler, head of Marine MAN Engines.
Through a series of modifications, MAN engineers have managed a power increase of 100 hp (74 kW) respectively, compared to the previously most powerful V12 and V8 engines. The performance-oriented design is supported by an improved injection system and new turbo charger. This is aided by newly developed cylinder heads and an adjusted cooling system which noticeably provides thermal relief for the engine with its high performance, the company said. Additionally, a new crankcase which has been reinforced in significant areas, ensures high performance throughout the entire engine’s long service life. Typical for MAN Engines, the highly efficient combustion allows the V12-2000 and the V8-1300 to run quietly, as is, and with low fuel consumption.
The superior engine performance allows shipyards to access additional possibilities for equipping larger ship series of around 100 feet with MAN engines. Additionally, as the most powerful V8 engine on the market, the V8-1300 makes it possible to integrate the highest-performing engines into existing applications.
Both engines meet the currently applicable emissions requirements US EPA Tier 3 as well as IMO Tier 2, and can thus be operated in all common and popular areas. With the introduction of both new engine types, MAN Engines offers a gap-free power range for yachts from 730 to 2000 hp (539 to 1471 kW) for V8 and V12 engines as well as the following inline six-cylinder engines: i6-730, i6-800, V8-1000, V8-1200, V8-1300, V12-1400, V12-1550, V12-1650, V12-1800, V12-1900 and V12-2000.
The V12-2000 and the V8-1300 will be shown from Sept.11-16 at the Yachting Festival in Cannes. Jetée booth 171 and 178.
