As the flagship model in the Cummins QS series, the QSK23 has long been active in the heavy-duty industrial field due to its high performance and durability.This 23-litre displacement inline six-cylinder engine is designed for extreme working conditions, balancing power output and fuel efficiency, and has become a common choice in the mining, power generation, marine and construction machinery sectors.

Core Advantages



  • Balance of power and efficiency
    With a maximum power of up to 895kW (1,200hp) and peak torque of over 4,600N-m, the QSK23 achieves high torque output at low speeds and reduces energy consumption.Its high-pressure common rail fuel system and intelligent electronic control technologies (such as the ADEM™ module) ensure precise combustion control and meet the stringent National IV and Euro V emission standards.

  • Modular design for easy maintenance
    The engine adopts integrated component design, such as single-piece cylinder head and simplified piping layout, which significantly reduces the number of parts and lowers the failure rate.Reasonable layout of daily maintenance window, high replacement efficiency of wearing parts such as filter element and sensor, reducing equipment downtime.

  • Extreme environmental adaptability
    QSK23 passes high temperature, high dust and high vibration tests, and is equipped with a multi-stage filtration system and enhanced cooling module (optional dual-circulation cooling), which guarantees stable operation in environments ranging from -30°C to 50°C, and is suitable for harsh scenarios such as mines and deserts.


Typical application scenes



  • Mining machinery: mining trucks, drilling rigs, loaders

  • Power system: standby generator sets, distributed energy resources

  • Ship propulsion: inland waterway cargo ships, harbour tugs

  • Industrial power: compressor, pump set drive


User feedback and market validation


The reliability of the QSK23 is outstanding in long-term operation.For example, a Central Asian mine user has reported that its equipment has operated continuously for more than 20,000 hours without major failures, and the maintenance cost is about 15% lower than that of similar models.Cummins global service network further guarantees the supply of spare parts and technical support, reducing users' worries.
