C18

Features

  • High Power Density

    C18 engines with series-turbocharged ratings above 560 kW (755 hp) have excellent power density that utilize a compact, single-can diesel oxidation catalyst (DOC) aftertreatment system. The DOC is a maintenance-free, passive aftertreatment solution that eliminates the need for thermal management.

  • Reliable, Quiet, and Durable Power

    World-class manufacturing capability and processes coupled with proven core engine designs provide reliability, quiet operation, and many hours of productive life.

  • Fluid Efficiency

    Fluid consumption has been optimized to match operating cycles of a wide range of applications while maintaining low operating costs. No diesel exhaust fluid (DEF) is required on these C18 variants which means a lifetime of low costs of operation.
