FEATURES & BENEFITS

Electronic Unit Injector fuel system featuring 10-20 percent higher injection pressure than other 3500 Family engines

Caterpillar ADEM II Electronic Engine Control/Monitoring System that provides infinitely variable injection timing and a state-of-the-art monitoring and protection system with self-diagnosing electronic sensors

“Deep Crater/Low Crevice Volume” twopiece articulated piston design with forged steel crown and cast aluminum skirt that enhance combustion efficiency to provide improved fuel efficiency and lower levels of gaseous and visible emissions

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
