Description

DLA58 EFI 58cc UAV Engine with Auto Starter & Alternator – 6.0HP Gasoline Power System

The DLA58 EFI Engine (DLA58UAE) is a high-efficiency 58cc single-cylinder gasoline engine specifically designed for fixed-wing UAVs with take-off weights of up to 18kg. Combining the benefits of an Electronic Fuel Injection (EFI) system with a powerful 400W integrated starter and alternator unit, this engine is engineered to deliver reliable power, fuel efficiency, and operational stability—even at high altitudes. The EFI system ensures precise fuel injection for consistent ignition and throttle response, while the lightweight alternator provides continuous onboard power for avionics and sensors.

Whether you’re operating in high-altitude conditions or executing long-endurance missions, the DLA58UAE stands out with its aviation-grade connectors, rugged mechanical design, and durable CNC-machined components. It supports a wide RPM range of 1600–6700, delivering up to 14.5kg of thrust at 1000m altitude. Fuel calibration is optimized through test-bench tuning according to the specific propeller you choose, guaranteeing maximum engine performance. Trusted by UAV integrators worldwide, the DLA58 EFI is your go-to propulsion system for professional drone applications.
