02
Extreme Performance
Achieving the maximum ground output power of 100 hp/L, the performance of 10000ft does not decay, and the continuous airworthiness at 20000ft.
03
Energy Saving and Environmental Protection
Compared with similar products, the fuel consumption is reduced by 10%, and the effective cruising range is increased by 10%.
04
Reliability and Durability
The integrated modular design, redundant design and the application of high-strength lightweight materials improve the reliability under all environmental conditions. TBO time can reach 2000h.
D4D20
The D4D20 engine adopts the latest high-efficiency combustion system + high-pressure common rail fuel injection system. The maximum net power is 139kW, the maximum output torque is 370Nm, and the fuel consumption is reduced by 10%, which can greatly increase the cruising range. The single-cylinder high-pressure common rail direct injection system independently and accurately corrects the fuel injection quantity, improves the working uniformity of each cylinder, reduces vibration, and has a high-pressure ratio turbocharger, which is more capable of adapting to high altitudes, and has no attenuation at 10,000ft altitude. The integrated modular design combined with high-strength and lightweight materials makes the engine lighter and more compact, and adopts technologies such as dual-redundant design of sensors and ECUs, high nickel-based valves, and the overhaul interval is as high as 2,000 hours.
