Best-Selling Sensor Engine Position Suppliers – Cummins QSNT855 Engine Assembly – Raptors Detail:
Porduct application
NTA855 has many uses. It can be equipped with generator sets. For example, it can be equipped with generator sets for ships. It can also be equipped with vehicles. If equipped with vehicles, it is mainly construction machinery, bulldozers, excavators, cranes, etc.
Advanced design and reliable performance:
Cylinder block: made of high-strength alloy cast iron, with good rigidity, low vibration and low noise.
Cylinder head: Four-valve design per cylinder, optimized air/fuel mixture ratio, effectively improving combustion and emissions; one head per cylinder, easy maintenance.
Camshaft: The single camshaft design can accurately control the valve and injection timing, and the optimized cam profile can reduce the impact force and improve the reliability and durability.
Crankshaft: Integral crankshaft made of high-strength forged steel. The induction hardening process of fillet and journal can ensure higher fatigue strength of the crankshaft.
Piston: Using the latest aluminum alloy casting technology, the design of ω-shaped head and barrel-shaped skirt can compensate for thermal expansion and contraction to ensure a good fit.
