Nylon oil tank has good shock resistance and long service life. Aluminum alloy die-cast water tank has better heat dissipation effect.

The diesel filter specially designed for National IV engine models uses imported filter elements and filter paper, which has good fuel filtration effect and higher filtration efficiency. The imported materials and customized alloy-plated special piston rings have higher wear resistance and longer service life.

The entire series uses P-type fuel injectors, which have better fuel atomization effect, low fuel consumption, fast acceleration, and stronger horsepower. The gear cover structure with enhanced design is made of high-strength alloy material and is durable.

It adopts high-strength gear material, nitriding treatment, 7-level precision, more precise transmission accuracy, better noise reduction and wear resistance.

It is upgraded and developed based on the Changfa Golden Crown series models to meet the requirements of non-road National IV emission regulations.

The high-pressure fuel injection pump adopts an innovative structural design and is made of high-strength pump body materials, with high injection pressure and more reliable performance.

The cylinder liner inner cavity honing reticulation technology is adopted, combined with the upgrade and optimization of the friction pair of the whole machine, which effectively reduces fuel consumption and emissions.

Innovative valve auxiliary processing technology fully guarantees the stable operation of the intake and exhaust systems and ensures that exhaust emissions meet standards.
