1. Modular Design
Water pump, oil pump, and oil cooler are incorporated into the engine block. The inlet pipe and cylinder head are combined with each other.
Function: The modular design, used by our H series engine, allows it to reduce the quantity of engine components, improving its reliability and lessening intake resistance.
Advantages: Compact structure, high reliability.

2. Patented Design of Strengthening Rib on the Engine Block
Function: High rigidity and high stiffness
Advantages: Reducing the vibration and noise.

3. Standardized Accessories Parts
Function: Better compatibility and rigidity
Advantage: Easy maintenance

4. Electronic Governor
Function: This H series engine is controlled by the electronic governor with high accuracy, meeting the highest requirement for steady state rate of power station.
Advantages: Better steady-state rate and more accurate instantaneous rate

5. Integral Cylinder Head, High Flow Coefficient and Low Eddy Current Airway Design
Function: The intensity and rigidity of cylinder head is greatly improved and this optimized design of airway meets these demands such as high power, low emission, low fuel consumption, and so on.
Advantages: Lower vibration, lower noise, and less fuel consumption.
