Products
Global supply chain, achieving international quality level
Bosch common rail system, ensuring high durability and reliability
Use of a high-strength cylinder block and an integral cylinder head, ensuring higher strength and stability
Use of a double-grid connecting rod bearing bush with higher bearing capacity, achieving stronger explosion pressure resistance and more reliable operation
Good environmental adaptability, with the adaptive temperature range of -30°C~40°C
Maximum torque: 1,150 N.m; torque reserve coefficient: 1.3
Focus on low-speed performance, ensuring better low-speed dynamic responsiveness and higher gradeability
BOSCH common rail system, ensuring more accurate injection and high injection pressure (up to 1,600 bar), thus greatly reducing fuel consumption
Application of a four-valve structure, increasing air intake and reducing fuel consumption
Application of Yuchai's patented open combustion chamber technology, achieving lower fuel consumption
