C18
Cat® C18 Diesel Engine
DESCRIPTION
This Cat® C18 engine variant equipped with a serial twin turbocharged-aftercooled system is capable of achieving power between 563-597 kW (755-800 hp) @ 1800 rpm while meeting EU Stage V emission standards.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.
