QSZ13
Cummins

The Cummins QSZ13 series is a robust and efficient 13-liter diesel engine platform designed to deliver superior power, reliability, and fuel efficiency for demanding industrial applications. This versatile engine is engineered to meet the rigorous needs of construction, mining, and energy sectors, providing high-performance output and low total cost of ownership.
Below are the key specifications for different models within the QSZ13 series.
The QSZ13 engine is a versatile power source for a wide range of heavy-duty machinery, including but not limited to:
Construction Machinery: Powering key equipment such as excavators, wheel loaders, bulldozers, and cranes.
Industrial Compressors: Specifically applied as the drive engine for industrial air compressors (e.g., used in the LiuGong CSH1320A compressor).
Mining Equipment: Used in demanding applications like mining dump trucks and other mining-specific machinery.
Agricultural and Specialized Machinery: Providing reliable power for high-power agricultural machinery such as forage harvesters and cotton pickers.
Other Applications: This platform is also suitable for power generation sets, pump drives, and certain marine applications.
The QSZ13 series incorporates advanced engineering to deliver exceptional performance and durability.
XPI (Extreme Pressure Injection) Fuel System: Utilizes an ultra-high-pressure common rail fuel system with injection pressures reaching up to 2400 bar. This ensures superior fuel atomization for more complete combustion, resulting in lower fuel consumption, reduced emissions, and increased power output.
Robust High-Pressure Design: The engine is built with high-strength materials, including an integrated full-steel piston and a reinforced cylinder block. This robust construction enables it to withstand peak combustion pressures as high as 230 bar, ensuring outstanding durability and reliability under heavy loads.
Intelligent Electronic Control System: Features a full-authority electronic control module (ECM) that continuously monitors and optimizes engine performance. This "smart brain" provides precise fuel injection control, system diagnostics, and protection, enhancing overall efficiency and operational safety.
Enhanced Performance Features: The engine is designed for superior operational capability, including excellent cold-start performance without aids at temperatures as low as -15°C (and -30°C with assistance). It also employs a high-efficiency turbocharging system for rapid response and high power density
