Düsseldorf Boat Show: mtu Presents New 2000 CR Marine Engines

Posted on January 20, 2004

MTU Friedrichshafen is unveiling its new 2000 CR marine engines at the Düsseldorf Boat Show.
  • High power output - low weight
  • Four cylinder variants from 895 to 1792 kW (1200-2400 PS)
  • Series Production from Summer 2004

Düsseldorf - MTU Friedrichshafen is unveiling its new 2000 CR marine engines at the Düsseldorf Boat Show. They have been designed to ensure high power output and engine power, compactness and low weight, and are capable of 20 percent more propulsive power than the engines in the current 2000 series. Even so, with a power to weight ratio of 1.99 kg/kW (1.48 kg/HP), the new engines are very light. The 2000 CR engines are fitted with several innovative technologies, including common rail, compound turbocharging and newly developed electronics. This makes them the most modern and powerful yacht engines on the market and among the lightest in their class.

The new 10V 2000 CR is capable of the same power output as the currently available 12V 2000, but its bulk volume is one third lower and it weighs 20 percent less. This allows for smaller yacht engine compartments and correspondingly larger cabins and effective usable space. The lower weight has a positive impact on speed and handling.

Four Cylinder Variants from 895 to 1792 kW (1200-2400 PS)

Four cylinder variants (8V, 10V, 12V and 16V engines) cover the power outputs 1200, 1500, 1800 and 2400 HP (895, 1120, 1344, 1792 kW). A new addition to the series is the 10-cylinder model, which bridges the gap between 8V and 12V, which was existant with the preceding 2000 series. The high power output of the 16V reduces the step up to the 4000 series, which is used in fast ships with a power output of 2735 HP (2040 kW). The 2000 CR engines offer a power to cylinder capacity ratio of 112 kW (150 HP), 20 percent more than the predecessor model. The engine speed range has also been increased to a maximum 2450 rpm (overloadable with 50 rpm). Low emission levels and low fuel consumption ensure that the engines comply with the EPA Tier 2/Euro 2 emission standards and keep fuel costs down.

The 2000 CR engines were designed as marine engines from the outset. This distinguishes them from the engines of the preceding 2000 series, which were derived from truck engines. Optimized adaptation to marine applications was therefore possible for the 2000 CR. This also includes the fact that the surface temperatures should not exceed 220 degrees Celsius anywhere on the engine (safety regulation as per SOLAS). Measures to ensure this include the special design of the engines with a charge air cooler integrated into the engine Vee, water-cooled turbochargers and triple-wall fuel lines.

The new series has smooth contours without compromising on ease of maintenance or the possibility of installing peripheral components. On the contrary, the engines are now easier to maintain. The interfaces on the engine as well as the "footprint" are designed in such a way that it is possible - with suitable gearing - to use the new engine instead of the previous engine without additional changes in the construction of the boat. Exhaust gas removal is easier than before, as the new engines only have one exhaust gas outlet instead of two as in the currently available engines. In terms of design, the service block on the free engine side, on which the cooler, filter and fuel lines are housed, has been retained. Service is also made easier by the new electronics, which enable optional remote access engine data via an internet connection. This makes fleet management much easier.

Series Production from Summer 2004

The 2000 CR engines are set to gradually replace the engines of the current 2000 series. Firstly, the 8V and 10V variants will be built as of summer 2004, followed by the 12V and 16V versions from 2005. The first areas of application for the new 2000 CR engines are yachts, patrol boots and fast commercial ships, for example fast ferries. At a later stage, the engines are intended to be available for other applications, such as medium-speed and low-speed commercial ships.
