• Overview

Engine Design

World-class reliability and durability
 - Medium speed long-stroke engine design
 - Compact cylinder head design
 - Nodular cast-iron block with integrated ducts for lubricating oil and charge air
 - Engine design based on the higher requirements of crude oil
 - High efficiency turbocharger
 - Cylinder liner semi dry, only cooled outside the engine block
 - Compact module for lower valve drives and injection pump drives with cam followers
 - Flexible Camshaft Technology optimizes valve operation to maintain low emissions
 - Super fine honed cylinder liner for low lube oil consumption
 - Hardened piston ring grooves
 - Diamond coated piston rings

Ease of Installation

Standard modular design allows for ease of installation and reduced complexity
 - Low installation cost with auxiliary systems mounted on engine
 - Cooling water system with simple plug-in connections

Improved Serviceability

Large inspection openings for convenient access to core engine components
 - Core engine components designed for reconditioning and reuse at overhaul
 - Worldwide dealer network with factory-trained technicians means that parts and support are never out of reach
 - Segmental camshaft design
 - Split connecting rod design for quick piston removal
 - Individual camshaft segments for easy removal
