Cummins QSB6.7 CPL3857 construction machinery engine
Cummins QSB6.7 CPL3857 is a high-performance diesel engine designed for construction machinery, agricultural equipment and medium-duty commercial vehicles. It provides a powerful output of 385 horsepower with a displacement of 6.7 liters, while meeting the world's most stringent emission standards. As a star model of the Cummins QSB series, its CPL3857 configuration has achieved breakthroughs in fuel efficiency, reliability and intelligent management, becoming the preferred power in the fields of mining, infrastructure and long-distance transportation.
Precise balance of power and efficiency
Power/torque: 385 horsepower (287 kW) @ 2200 rpm, peak torque 1250N·m @ 1500 rpm, low-speed high-torque characteristics significantly improve the equipment's climbing and heavy-load starting capabilities.
Intelligent combustion control: Adopting the XPI ultra-high pressure fuel injection system (2200 bar), the fuel atomization efficiency is increased by 15%, and the comprehensive fuel consumption is reduced by 6% compared with the previous generation.
Adaptability to harsh environments
Extreme working conditions verification: It can operate stably in extremely cold environments of -30℃ and high temperatures of 55℃, equipped with a two-stage air filter and enhanced cooling module, and its dust and heat dissipation performance is industry-leading.
Emission compliance: It meets the Tier 4 Final/EU Stage V standard, integrates DOC+DPF+SCR post-treatment system, and has a soot particle capture efficiency of ≥99%.
Long-term maintenance design: The oil change cycle is extended to 500 hours, the filter element is integrated with a quick-release structure, and the daily maintenance time is reduced by 40%.
Modular maintenance: Core components such as cylinder blocks and turbines are independently packaged, supporting rapid on-site replacement and reducing downtime losses.
Application scenarios
Excavators, loaders, bulldozers.
Agriculture and special vehicles.
Combine harvesters, large tractors.
Medium-sized transport vehicles.
