Product parameters

Product advantages

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

• Power: 103kW~125kW, maximum torque: 520N•m/(1400~2100)r/min.
• The engine has higher torque and higher power when compared with competing products of same displacement.

Comfort

• The rear-mounted gear chamber, enclosed flywheel housing, and plastic cylinder head cover are adopted, which effectively reduce noise, making the rated noise 4dB(A) lower than that of competing products.
• 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.
