QSK19 Engineering Machinery Engine – Exceptional Power, Reliability, and Efficiency

The QSK19 Engineering Machinery Engine combines cutting-edge technology with proven reliability to deliver high performance in demanding applications. With advanced fuel systems and robust design, the QSK19 is built to meet the toughest challenges in the engineering machinery sector.

Superior Performance

Equipped with a globally leading high-pressure common rail fuel system and a fully electronic control module, the QSK19 ensures ultra-high fuel injection pressure. The engine benefits from a vortex and harmonic-style integrated air intake, along with Cummins’ exclusive high-pressure ratio turbocharger, which optimizes power delivery and transient response. As a result, the engine demonstrates exceptional adaptability to altitude, temperature, and varying load conditions, ensuring peak performance at all times.

The engine offers high torque, powerful performance, quick transient response, and excellent fuel efficiency, all while maintaining a high torque reserve for demanding tasks.

Long Durability

The cylinder block and cylinder head feature a high-strength integrated design, minimizing failure rates and ensuring long-lasting durability. With these features, the QSK19 has earned an excellent reputation for reliability in the field. Additionally, the engine benefits from advanced systems like the pre-lubrication system, Centrifugal Guard? centrifugal filter, CENTINEL? continuous oil renewal system, and dual-stage filtration. These technologies extend maintenance intervals and reduce the likelihood of engine startup failures.

Emission Compliance

The QSK19 complies with the European Union’s Stage V (EU Stage V) and the United States’ Tier 4 (EPA Tier 4) emissions standards for non-road mobile machinery. Models with a power output of 560kW and above are also certified for China’s Stage III (CSIII) emissions standards, making this engine a versatile choice for global markets.

Easy Maintenance

The QSK19 offers easy diagnostic and monitoring capabilities with its INSITE? engine monitoring and diagnostic software, based on the Windows operating system. This software provides a user-friendly interface with great flexibility, enabling fast and accurate engine fault diagnosis.

The engine’s modular design is compact and integrated, allowing components to be easily separated and reused. Its shared platform and high parts compatibility ensure simplified maintenance and reduce overall operating costs.
