Skylark

The "Lark" DB416 heavy oil piston aviation engine adopts technologies such as opposed structure, efficient and reliable combustion system, high-pressure common rail technology, high-pressure ratio supercharging system, lightweight design, and full authority digital control. It has the following application features: 1. High service ceiling (power does not decline at 5000m, and the maximum altitude is 12000m); 2. High endurance (heavy oil engines have high thermal efficiency and low fuel consumption, with a cruise fuel consumption point of 220g/kWh, which is 30% lower than the existing power, and the endurance time can reach 40 hours). ； 3. Wide application environment (full electronic control, full aircraft liquid cooling, not restricted by environment); 4. High power-to-weight ratio (up to 1.0kW/kg, compared with 0.7-0.8kW/kg of heavy oil engines in the industry); 5. Heavy oil fuel (standardized military fuel, breaking the ban on heavy oil sales, achieving self-reliance and control); 6. Breaking the "bottleneck" 100% independent property rights, 100% self-reliance and control, 100% domestic production.
