Overview
The Cat® C32B engine is a powerful and versatile solution for commercial and high performance applications, offering a rated power range of 1200 to 1700 bhp. It meets stringent emissions standards, including IMO II, IMO II/III, and U.S. EPA Tier 4. The Cat C32B engine has an optimized design to enhances power density, deliver more power without significantly increasing size or weight. Additionally, its improved durability reduces maintenance needs and extends operational life, thereby lowering the total cost of ownership. This combination of high-power output, strict emissions compliance, and cost-effective durability makes the Cat C32B engine an excellent choice.
Benefits
Power Density
The enhanced engine design boosts cylinder pressure and power output, ideally suited for
your most demanding commercial marine applications.
Integration
The innovative airless aftertreatment design streamlines vessel installation and reduces air compressor maintenance which can lower your total cost of ownership.
Durability
Optimized core component design delivers a more robust, high performance engine compared to previous models.
