Heavy Fuel Engines are engineered for professional UAV applications that demand high efficiency, long endurance, and reliable performance under extreme conditions. Designed to run on heavy fuels such as kerosene or JP-8, these engines are ideal for military-grade drones, industrial surveillance UAVs, and long-range autonomous systems. Compared to standard gasoline engines, heavy fuel engines offer greater fuel stability, lower volatility, and improved safety, especially in high-temperature or high-altitude operations. Their compatibility with commonly available aviation fuels also makes them the preferred choice for government and defense sectors.

At ENGINEPORT, our heavy fuel engine lineup features advanced hybrid systems with integrated power generation, auto-starters, and electronic fuel injection (EFI) for optimal control and efficiency. Whether you’re flying at 10,000 feet or operating in desert heat, our heavy fuel engines deliver dependable performance when it matters most.
