High reliability and high quality - long service life, high performance, fast acceleration - more powerful

1. Using nylon fuel tank, it has good seismic resistance and long service life.

2. Aluminum alloy die-casting water tank, with better heat dissipation effect.

3. Using imported filter cartridges and filter paper, the national IV model's dedicated diesel filter has good fuel filtration effect and higher filtration efficiency.

4. The uniquely designed rolling special piston ring has higher wear resistance and longer service life.

5. The entire series adopts P-type fuel injectors, which have better fuel atomization effect, lower fuel consumption, faster acceleration, and stronger horsepower.

6. The gear chamber cover structure with reinforced design is made of high-strength alloy material, which is durable and long-lasting.

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

8. Adopting the flexible structure design of the crankshaft made by Changfa Original Factory and conducting dynamic balance testing, the vibration of the whole machine is effectively reduced, and the dynamic balance is perfectly controlled. At the same time, Changfa's patented design of automatic oil injection lubrication function at the front end of the crankshaft is added to actively lubricate the gears, effectively reducing the noise inside the gear chamber cover and ensuring excellent quality and performance of the whole machine. (Chinese utility model patent: Lubrication structure ZL.3 for single cylinder engine)

Low fuel consumption, low emissions, and low vibration - good fuel efficiency, economical and environmentally friendly, and more comfortable to use

1. Upgraded and developed based on the Changfa Golden Crown series models to meet the requirements of non road National IV emission regulations.

2. The high-pressure fuel injection pump adopts innovative structural design, selects high-strength pump body materials, has high injection pressure, and more reliable performance. (Chinese utility model patent: ZL.8)

3. Adopting internationally advanced cylinder liner inner cavity honing mesh technology, combined with the upgrading and optimization of the friction pair of the whole machine, effectively reduces fuel consumption and emissions.

4. Advanced valve pair processing technology fully ensures the efficient and stable operation of the intake and exhaust systems, ensuring that exhaust emissions meet standards.

Widely used in agricultural transport vehicles, tractors, water pump units, irrigation machinery, construction machinery, generator sets, tracked rotary tillers, small construction machinery, and other power supporting fields.
