1. Common-rail Fuel Injection Systems and High-Pressure Pump: Generates up to 2,200-bar injection pressure for maximum efficiency, optimizing the combustion pressure curve through multiple injections. 

2. High Power Density:  The HGY Series delivers exceptional performance in terms of emissions and power density (up to 37.9kWm/L).  The high specific power density reduces footprint and has a great impact on the total life cycle carbon footprint.

3. Single Cylinder Prototype:  The design of the piston head and the fluid analysis is key for engine efficiency and performance. Yanmar has spent thousands of engineering hours in this stage of the development.

4. Fast Response:  Fuel injection makes a huge difference in the power generation application where the speed of response is vital. The ECU can react to sudden changes in speed in milliseconds. Engine starting in less than 8 seconds. This engine can perform within ISO8528-5 G3 class conditions.

5. Intuitive Engine Control Unit (ECU): The ECU includes several physical parameters for optimal control of the injection system. The control system includes integrated, intuitive, operable diagnostic software, which allows remote monitoring of the engine and generator.

Fuel Consumption | Best-in-class

HGY generators are designed for maximum efficiency and optimal fuel consumption, thanks to a high-pressure common rail injection system, advanced piston design, and high-power density. This results in lower operating costs, reduced emissions, and excellent autonomy, making the HGY Series one of the most competitive solutions on the market.

Serviceability | Extended Service Intervals

The HGY Series is engineered for easy maintenance, with all key consumable parts accessible from one side. A modular design ensures high parts compatibility across models, reducing spare parts inventory and simplifying servicing and technician training. Extended service intervals include up to 10,000 hours for top overhaul and 30,000 hours for major overhaul in continuous operation.
