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.
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.
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.
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.
A one-piece casting, wall structure fully supported by the head gasket, thicker flame deck and resizing and relocation of cooling bores significantly improves the strength and design margins of the assembly’s cylinder head.
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.
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.
