Wabtec Marine (previously GE) V250 Diesel Engine
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
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.
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
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
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.
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.
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
