Design of the QSX15 engine centers around integration and high reliability:
Integrated module design: The engine adopts an integrated fluid circuit, reducing external hoses and pipelines, thereby reducing the potential risk of leakage and enhancing reliability under harsh operating conditions.
24-valve double overhead camshaft: It is the first heavy-duty diesel engine to adopt this technology, and with the design of 4 valves per cylinder, it significantly improves the intake and exhaust efficiency and engine response speed.
Robust body structure: The cylinder block and cylinder head are designed with high strength, and the number of parts is fewer compared to similar products, effectively reducing the failure rate
