Larger diameter (98 mm vs. 92 mm bore) camshaft for higher injection pressures, shorter injection durations, and less gear train torsional vibration
Strengthened fuel injection actuation system and rear gear train to maintain reliability and durability while providing higher injection pressures
Center-mounted low inertia turbochargers (four on 3512B and 3516B; two on 3508B) on EPG models
Dual rear mounted turbochargers on all marine configurations
Separate circuit or sea water aftercooling to supply the optimum temperature air to the combustion chamber to reduce emissions and fuel consumption and maximize power output
Streamlined intake and exhaust manifolds to reduce parasitic pumping losses and increase combustion efficiency
Thermo-laminated heat shields on all marine configurations to maintain surface temperatures below Marine Classification Society regulations and to retain more exhaust gas energy for increased turbocharger performance
Redesigned aftercooler-to-intake manifold joints that use formed elastomeric seals and substantially fewer fasteners to give superior sealing characteristics and easier serviceability
Pin-type connector for easy connection of Caterpillar Engine Technician electronic service tool which delivers superior diagnostic capability to determine exact causes of engine faults
Formed elastomeric seals replace gaskets on rocker arm bases eliminating gasket relaxation to maintain consistent dimensions for valve lash and injection settings and nuisance-type oil leaks.
