The C8.3 is built to last, with a cast-iron unitized block with fewer parts than traditional diesel designs, fewer joints and simplified maintenance. This block has been structurally reinforced to resist bending and torsion, eliminating 1 dBA of noise output. Even the gaskets have a special edge-molded design to eliminate possible leakage and reduce oil consumption. Heavy-duty features include:

• Heavy-duty pistons with Ni-Resist inserts for longer life
• Mid-stop cylinder liners that reduce cavitation and improve rebuildability
• Plateau honing on the cylinder liners for near-perfect cylinder geometry, virtually eliminating oil consumption
• A robust Holset HX40 wastegated turbo with excellent low-end torque
• An in-line fuel pump that delivers higher injection pressures for cleaner combustion, more power and flexible fueling
• A helical gear train that operates smoother and quieter
• A proven design with millions of C Series engines in service everywhere around the world
