DLE170 170cc EFI Engine

Description DLE170 EFI ENGINE — High-Performance Electronic Fuel Injection Engine for Industrial UAVs The DLE170 EFI is a high-power, high-efficiency two-stroke engine developed specifically for industrial UAV applications. Equipped with a fully upgraded electronic fuel injection (EFI) system, it delivers stable performance, superior fuel economy, and reliable operation across a wide range of environments. Its outstanding power-to-weight ratio makes it an ideal choice for heavy-lift fixed-wing platforms, hybrid VTOL systems, and long-endurance missions. Key Features Advanced Electronic Fuel Injection System The DLE170 EFI uses a precision-controlled EFI module with a self-priming fuel pump and closed-loop pressure regulation. Fuel is delivered consistently without the need for a return line, ensuring stable operation during high-G maneuvers, climbing, banking, and long-distance flights. The system maintains optimal combustion under varying temperatures and altitudes, offering far better stability than carburetor-based engines. Real-Time Engine Telemetry The EFI controller outputs real-time running data through an RS232 protocol, allowing seamless integration with professional flight-control systems. Users can monitor fuel status, RPM, temperature and engine health in real time—critical for mission safety and performance tuning. High Power Output with Low Weight With a maximum output of 17.5 HP at 8,500 rpm, the DLE170 EFI provides exceptional thrust for medium-to-large UAV platforms while keeping the overall system weight low. This efficiency directly contributes to longer endurance, higher payload capacity, and improved operational reliability. Designed for Harsh Environments The engine is engineered to operate between -20°C and 50°C, ensuring dependable performance in extreme cold, desert heat, high-altitude regions, and maritime operations.
