YC6K Model characteristics

 

a. High-strength composite-alloy material, and gantry type symmetrical cylinder are adopted; deformed cast iron reinforcing plate is adopted for strengthening; integrated water seal ring design is adopted for cylinder block to improve the strength of cylinder liner and deformation resistance.

 

b. High-efficient top-down cooling technology is applied, which can greatly reduce the temperature sensitivity of core parts such as engine cylinder head; and there is a market decline in mechanical strength retrogression of the material due to heat; the whole engine stiffness, combustion performance and adaptability to work at differ-stiffness, combustion performance and adaptability to work at different temperatures can be improved obviously.

 

c. Full-balanced high-strength integral forging crankshaft, obliquely split connecting rod employing the cracking technology, high-quality bearing bush material and wide bearing surface, and GPT materials technologies are adopted, which reduce the gap between auxiliary cylinders and the lateral force; full piston steel ring is applied, which can greatly reduce wear and deformation.

 

d. Valve mechanism: the designs of high-strength camshaft and large angle valve are applied, which ensure good wear resistance and less contact stress, and greater pressure bearing capacity.

 

e. World advanced electronically-control high pressure common rail technology is applied, which ensures fast transient response speed; and the demands from different users for sensitivity and stability can be satisfied.
