Reliability

The wet cylinder liner, gantry type drum engine block, integral cast iron cylinder head are adopted; and the new design of moving parts such as piston, connecting rod crankshaft and bearing shell is adopted. B10 life is 800,000km.
Weichai premium suppliers develop the relevant products according to the high reliability requirements in the heavy truck industry.
The engine block and the cylinder head are casted and machined by Weichai, ensuring high consistency.
Economy
Min. fuel consumption: 200g/kW.h.

Power performance

Comfort

The rear-mounted gear chamber, enclosed flywheel housing, and plastic cylinder head cover are adopted, which effectively reduce noise.
The standard engine block stiffening plate is used, which ensures a better engine vibration reduction performance than that of competing products. The optional secondary balance mechanism can reduce engine vibration further.

Adaptability

The modular design, compact layout of peripheral accessories, and various optional structures ensure a wider range of application.
The oil filter, alternator, starter and other parts of N platform are universal, ensuring the convenience of maintenance.
