ZT-T730cc 730cc Heavy-Lift UAV Engine

1. Premium 4-Cylinder Layout & Smart Ignition

Featuring an innovative horizontally opposed 4-cylinder layout form, this engine dramatically mitigates low-frequency vibration across a broad speed range of 2000-7500rpm. It integrates an opposed two-cylinder synchronous ignition mechanism with an intelligent CDI automatic angle igniter that performs automatic switching at 500 rpm, ensuring buttery-smooth idle performance and seamless throttling.

2. Aerospace-Grade Materials & Forged Components

Built for extended lifespans under grueling thermal stress, the engine block features a cast aluminum alloy cylinder wall treated with a premium ceramic nickel-silicon hardened coating. The piston utilizes precision oval grinding and top-tier aluminum alloy casting. The entire internal structure is driven by an ultra-robust, seven-piece forged combination crankshaft assembly designed to absorb massive torque impacts.

3. Optimized Fuel Systems & Massive Power Generation

The propulsion system offers two fuel delivery architectures: standard dual diaphragm-type all-around carburetors (built without traditional choke/injector nozzles) running at 17L/h, or an advanced high-altitude ECU EFI electronic fuel injection suite reducing fuel consumption to just 12L/h. With an optional integrated high-power onboard generator (800W / 2000W), it seamlessly powers high-draw avionics, heavy-duty servos, and mission payloads.
