Wabtec Marine (previously GE) V250 Diesel Engine

Making waves

GE’s V250 Diesel Engine

Wabtec Marine (previously GE) has been designing and building high-performance diesel engines for more than 40 years. Today, we’re one of the

leading manufacturers of medium-speed diesel engines in the world. In our V250 marine engine, we’ve combined the best features of earlier engine designs with advancements proven to deliver efficiency, reliability and performance advantages

6´5 % Fuel Saving while meeting IMO Tier II

The V250 proves it’s possible to

meet the emissions compliance

requirements of IMO Tier II

without sacrificing fuel efficiency.

In this engine, improved fuel

management, a combustion

system design and refined cooling

deliver fuel savings of as much

as 6.5%, compared to our earlier

engine designs.

25 %Greater power density in a compact design

A relatively large bore engine with

a narrow overall width and lighter

weight, the V250 packs a lot of

power into its footprint. Among

other features, its inlet and exhaust

manifolds are compactly arranged

between cylinder banks. Where

space is at a premium, the trim

design and high power-to-weight

ratio of the V250 give it a clear edge.

Engineered for

reliability and

maintainability

The V250 engine is designed not only for higher efficiency and lower emissions but also for improved reliability and maintainability. Designed with on-engine accessories, every critical component and system of the V250 was engineered, manufactured, tested, refined and validated extensively for reliability. For easier maintenance, a segmented camshaft, sectional exhaust manifold, unitized power assembly and other features simplify component removal and replacement. With impressive features, ratings and a full-power PTO, the V250 is sure to exceed your marine engine expectations. Wabtec Marine’s (previously GE) V250 diesel engines are available in 12-cylinder and 16-cylinder V configurations for mediumspeed duty with continuous power from 2,725 kW to 4,240 kW.

V250 engine systems

Advanced EFI

Designed for greater efficiency at varying

speeds and loads, the V250’s electronic

fuel injection features precise fuel control,

increased pressure capability and

refined timing. Optimization of the cam

profile, injection start, injection volumes

and flows, and control algorithms have

produced a relatively simple system,

proven reliable through extensive

validation.

Sophisticated control

Our controller drives the fuel-injection

system with advanced closing point

detection for better fuel economy and

emissions control. The system features

improved diagnostics and display of all

engine parameters and faults without

the need for a laptop computer. Engine

protection algorithms predict problems

earlier to avoid engine damage.

Sturdy mainframe

The mainframe of the V250 engine

features high-strength ductile-iron

construction. The main and connecting

rod bearing capacity provides greater

reliability and durability, and improved

ribbing in the cross-bolt area adds to

stiffness and lowers vibration.

Higher-efficiency turbocharger

We have taken a proven turbocharger design and leveraged the

aerodynamics expertise of our aviation business to enhance it.

Improved bearing strength, better rotor dynamics, a cooled housing

and integrated packaging create a high-performance, high-reliability

system. Turbocharger matching optimizes performance for various

speed ratings.

Heavy-duty crankshaft

Forged of high-quality steel and nitride-hardened for long life, the

V250’s crankshaft has single-piece construction with no bolted joints.

Large journal surface areas minimize loads, and dynamically balanced

counterweights reduce stress for longer crankshaft life.

Forged connecting rods

Exceptional strength, high stiffness and

large bearings are unique features of

our connecting rods. The large bearing

width and

optimized

oil groove

in the

bearing shell

improve oil

film thickness

and pressure.

One-piece liners

The stiff, one-piece,

mid-stop liner has an

integral external water

jacket that removes

the possibility of water

leaks. An anti-polishing

ring provides a durable

running surface, improving

lube oil consumption and liner life. The

top one-third of the liner is cooled.

Piston design

Our piston design

meets the increased

weight and pressure

requirements of the

V250 engine. The

improved skirt-andpin

boss provides

better lubrication and guidance. With

dynamics optimized through secondary

motion analysis, the piston design

lowers oil consumption, reduces blowby

and lengthens oil life.

Segmented camshaft

The camshaft in the V250 is arranged in

individual sections for easy inspection

and maintenance. Forged and

hardened camshaft lobes reduce wear.

Oversized journal bearings decrease

loads for longer camshaft life.

Better fuel efficiency

Greater power density

Higher reliability and maintainability

They’re all on board

It’s all here — in the technologically advanced, fuel-efficient, environmentally compatible diesel engine built by Wabtec Marine (previously GE).

It’s the product of more than six years in development and testing and nearly six million megawatt hours in service.

And with customization to the marine industry and competitive pricing, it’s ready to meet your marine power needs.
