MAN Truck & Bus To Expand Marine Engine Line

MAN Truck & Bus revealed it will introduce a new vee-configuration 12-cylinder diesel engine for heavy-duty marine applications at the SMM show in September. The new D2862 LE441 marine diesel will be rated 735 kW (985 hp), which is a significant increase from the existing D28 engines, the company said.

The company said that through use of a single-stage wastegate turbocharger with charge-air intercooler and adapted valve timing, the engine’s mean pressure was increased and power output raised by 73 kW over the previous D28 engines. In addition, a common rail fuel injection system with EDC control allows for a pre-injection stage, which provides significant benefits in terms of vibration and noise emissions, MAN said.

Engine design and materials

If break mean effictive pressures and ignition pressures are to be achieved, high-strength materials and a rigid engine block design are needed. The crankcases of the D20, D26 and D28 engine ranges are made of high-quality CGI-450 (compacted graphite iron). This material is much stronger than grey cast iron.

De har också CGI från Sintercast i sina  motorer sedan ett bra tag.

The engine is designed with extremely rugged technologies, like steel pistons and CGI iron crankcases that provide superior strength and durability over aluminum without sacrificing weight

Compacted Graphite Iron (CGI) Cylinder Block

Grainger & Worrall

The casting of major engine parts like the blocks and cylinder heads will be done by the British firm Grainger & Worrall, which has 75 years experience, operates 6 foundries, employs 400 people, and is recognized worldwide for its castings development and innovations.

Powertrain

With all the other weight savings onboard, less engine is needed to motivate a family Fusion, so the 1.0-liter EcoBoost I-3 is fitted, but with a bunch of further upgrades. The biggie is swapping cast iron for aluminum with compacted-graphite iron inserts to help tie the head bolts to the crankshaft bearings, so the engine block saves 45 percent

Detta kan bli riktigt stort. Ford verkar insett till fullo hela potentialen i CGI-användandet. Denna bil är en koncept men det är tydligt att CGI kommer mer och mer i mindre volymmotorer. Överallt där man behöver mer styrka är CGI intressant.
