Komatsu Engine

We are a comprehensive supplier of Komatsu engines, providing all series of engines used in Komatsu, Hitachi, Liebherr, and other heavy machinery. Our offerings include engines produced both in China and imported from global manufacturers.
In China, several joint ventures produce high-quality engines for heavy equipment. For example, Chongqing Cummins specializes in manufacturing robust models such as NTA855, KTA19, KTA38, KTA50, and electronic engines like QSK19, QSK38, QSK50, and QSK60, many of which are widely applied in Komatsu machinery. Similarly, Xi’an Cummins produces the versatile QSM11 engine, commonly found in mining and construction equipment, ensuring reliable performance under demanding conditions.
For Komatsu machines requiring imported engines, options include advanced models like the QSX15, QSK23, QST30, and QSK78. Notably, the Cummins QSK23 engine is frequently paired with Komatsu excavators, which often operate alongside mining trucks in large-scale projects.

Our product line also extends to engines for high-capacity Komatsu dump trucks and mining equipment. Whether for maintenance or upgrading, we provide innovative solutions, such as replacing discontinued models like the QSK45 with modern alternatives like the QSK50 or QSK38. Customers can trust us to supply genuine, high-quality engines and avoid risks associated with rebuilt units marketed as new.

Additionally, we supply MTU engines, which are commonly used in Komatsu’s heavy-duty applications, offering durable solutions for the most challenging environments. Our team ensures customers receive the best technical and economical options, making us the ideal partner for all Komatsu engine needs.
