Forced draft cooling method, by increasing the heat dissipation area of ​​the engine body and cylinder head heat sink, effectively reducing the oil temperature and the heat load of the whole machine, adopting the strengthened engine body optimized by the new finite element analysis design to ensure the stability of mechanical operation.

Imported steel piston rings are used to effectively avoid premature wear of pistons and cylinder liners, extending service life and lasting power.

The fuel injection pump with a new enhanced design has more reliable performance and high injection pressure. At the same time, it is equipped with a small-aperture, low-inertia P-type fuel injector, which has better fuel atomization effect, more complete combustion, stronger power and lower fuel consumption.

Multifunctional stable speed regulation system, automatic correction of fuel supply system, fast acceleration, clean combustion without black smoke; simplified structural design, integrating four functions of idling, speed regulation, emergency stop and fuel quantity correction in one, small speed fluctuation and more stable speed regulation.
