Engine Specifications
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
