GE’s New V250 Diesel Engine
Better fuel efficiency
Greater power density
Higher reliability & maintainability
They’re all on board
It’s all here―in the most technologically advanced, fuel-efficient, environmentally compatible
diesel engine ever built by 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.
The V250 Diesel Engine. It’s quite simply our best diesel engine ever.
The New V250 Diesel Engine
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
new V250 marine engine, we’ve
combined the best features
of earlier engine designs with
advancements proven to deliver
efficiency, reliability and perfor
mance advantages.
6.5%
6.5% fuel savings while meeting Tier 2
The V250 proves it’s possible to meet the emissions compliance requirements of U.S. EPA Tier 2 without sacrificing fuel efficiency. In this new engine, improved fuel management, a new combustion system design and refined
cooling together deliver fuel savings of as much as 6.5%, compared to our earlier engine designs. At the same
time, the V250 meets the EPA’s new, more stringent emissions guidelines as well as Marpol Annex VI standards.

25% greater power density in a compact design
25%
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.
100%
100% engineered for reliability and maintainability
The V250 is a brand new engine―designed not only for higher efficiency and lower emissions but also for
improved reliability and maintainability. 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.
GE’s V250 diesel engines are available in 12-cylinder and 16-cylinder V configurations for medium-speed duty
with continuous power from 2175 kw to 4240 kw.
V250 engine systems
Proven performance and operating advantages
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 PowerStar™ II 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.
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.
Sturdy Mainframe
The mainframe of the V250 engine is 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.
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.
Improved Power Assemblies
Our redesigned power assembly meets
the high-pressure demands as well as
the stringent reliability requirements
of the V250 engine, while retaining an
easy-to-maintain assembly concept.
The unit’s refined flow path enhances
combustion, fuel savings and reduced
emissions. The cylinder head, liner,
piston and connecting rod can be
easily removed as a single assembly.
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.
Rugged Cylinder Heads
A one-piece casting, wall structure fully supported by
the head gasket, thicker flame deck and resizing and
relocation of cooling bores has significantly improved
the strength and design margins of the assembly’s
cylinder head.
New Piston Design
Our new piston meets the increased weight and
pressure requirements of the V250 engine. The
improved skirt and pin boss provide better lubrication
and guidance. With dynamics optimized through
secondary motion analysis, the new piston design
lowers oil consumption, reduces blow-by and lengthens oil 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.
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.
