QSX12
Cummins
The Cummins QSX12 is a robust 12-liter diesel engine engineered to deliver reliable power and performance in the most challenging industrial environments. As part of the proven QSX platform, this engine is built for applications requiring a durable power solution with responsive performance and a low total cost of ownership.
The QSX12 engine is engineered as a prime mover for heavy-duty industrial equipment. Its primary applications include:
Construction & Mining Machinery: Powers excavators, wheel loaders, mining trucks, and drilling rigs. Its torque is also suitable for compactors and cranes.
Industrial Power Units: Drives high-capacity industrial pumps, air compressors, and generator sets.
1. High-Pressure Common Rail Fuel System for Efficiency
The engine features an advanced high-pressure common rail (HPCR) fuel system managed by full electronic controls. This technology enables precise fuel delivery and multiple injection events, resulting in improved combustion for better fuel economy, lower emissions, and reduced engine noise.
2. Durable Construction for Long Service Life
Built on a robust platform, the QSX12 is designed for longevity in severe conditions. Its heavy-duty construction incorporates durable components to withstand the high-stress cycles typical of industrial and construction applications, ensuring high reliability and extended service intervals.
3. Efficient Turbocharged Air Management
The turbocharged and air-to-air aftercooled (TTA) aspiration system forces a dense charge of cool air into the cylinders. This significantly enhances combustion efficiency and power density, providing strong torque at low RPMs for excellent load response and lugging capability.
