Noise Reduction Technologies. Noisereduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing case cover, sculpted crankcase and gear train refinements. Fuel Delivery. Multiple injectionfueldelivery involves a high degree ofprecision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating feweremissions and optimizing fuel combustion. This translates into more work output for your fuel cost. Advanced Diesel Engine Management(ADEM) A4 Engine Controller. TheADEM A4 electronic control module manages fuel delivery to get thebest performance per liter or gallon of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency. Cylinder Head and Piston Technology. The C11 has a cross-flow cylinder head with refined port geometry, which improves breathing and provides better combustion. The Monotherm/steel pistons have a forged steel design, which offers high strength, light weight and tighter tolerances. The result is better oilcontrol, minimal blow-by and long liner life.

Articulated Truck - 19427 Cat C11 Engine with ACERT Technology

A combination of proven systems and innovative new technologies, ACERT engines optimizeperformance while meeting EPA Tier 3 and EU Stage 3a engine exhaust emission regulations.

C11 Block. The one-piece, gray ironblock features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. Straight O-ring connection points reduce the loss of engine oil and fluids. ACERT Technology. The C11 ACERTengine introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability. The technology capitalizes on Caterpillar expertise in four core engine systems: fuel, air, electronics and after treatment. ACERT technology is a unique and revolutionary systems solution that enables Cat engines to meet today’s clean air regulations, thus establishing the building blocks for attaining tomorrow’s more stringent standards.
