Engine Model: QSX15 ISX15 X15

Application:
ISX15: The mainstay engine for heavy-duty trucks, widely used in tractors/cargo trucks, and partially in construction machinery (such as bulldozers and mining trucks) and generator sets. It was a mainstream electronically controlled common rail engine from 2007 to 2017.

QSX15: The off-road (construction machinery/marine/mining) version, commonly found in rotary drilling rigs, excavators, mining trucks, bulldozers, ships, and stationary power units. It emphasizes high torque and continuous high-load operation. It was gradually replaced by the X15 around 2014.

X15: The successor to the ISX15 (after 2017), covering heavy-duty highway trucks (same as the ISX15 model) and some off-road equipment. It adopts a more efficient SCR+EGR system. Some models (such as the X15 Performance Edition) are also used in special engineering vehicles, port traction, and power generation. In some materials, "X15" generally refers to common platform parts for ISX15/QSX15, but the original X15 is mainly aimed at compliant highway transportation. Although the three share some parts (such as oil pumps and rocker arms), the QSX15 is off-road certified, while the ISX15/X15 is on-road certified. The X15 is a technological iteration of the ISX15, while the QSX15 belongs to an independent off-road series. Currently (in 2026), new vehicles mainly use the X15, the ISX15 is more commonly found in used vehicles/old construction machinery, and the QSX15 is still in service in some heavy engineering equipment.
