Specifications

Did you know

• The Caterpillar C32 engine was introduced as a V12 diesel engine, designed to succeed earlier large-bore platforms like the 3400 Series. It was developed as a modern, electronically controlled powerplant, combining Caterpillar's legacy V-engine strength with updated systems to meet contemporary performance and emissions standards.
• The C32 is part of Caterpillar's C-Series engine family, positioned for high-horsepower applications in off-highway, marine, and power generation markets. Within the marine auxiliary engine lineup, it offers a higher displacement and power output compared to models like the C18.
• The C32 auxiliary engine is chosen for its ability to deliver substantial power for continuous duty cycles, emphasizing torque delivery, thermal stability, and structural strength. Its separate circuit aftercooling system (SCAC) reduces aftercooler corrosion by eliminating seawater circulation, contributing to lower owning and operating costs.
