The Cummins B4.5 is a robust, 4-cylinder diesel engine delivering 121–200 hp and 369–575 lb-ft torque, making it ideal for construction, agriculture, and industrial applications. With 16% more power and 11% more torque than its predecessor, it ensures faster cycle times and improved machine productivity. Its fuel efficiency is enhanced by up to 3%, and even more in idle-heavy operations, thanks to Cummins Stop-Start technology. The EGR-free design simplifies cooling requirements and improves reliability. Multiple installation options—including front/rear sump, various PTOs, and turbo orientations—make integration flexible. The compact Single Module™ aftertreatment reduces size and weight significantly. With remote diagnostics via Connected Diagnostics™ and support from Guidanz™, the B4.5 minimizes downtime and lowers total cost of ownership—ensuring performance, durability, and value in tough environments.
