Product Overview
ZT-T120 Twin Cylinder Engine
The ZT-T120 is a twin-cylinder, air-cooled, two-stroke engine producing 11.22hp (8.25kW) with a displacement of 120cc. It delivers 26.5kg of static thrust at 100m altitude and 23.5kg at 1800m, supporting platforms with a maximum take-off weight of 60kg. Featuring automatic advance angle CDI ignition, mixture lubrication at 25:1–30:1, and compatibility with both push and pull propeller configurations, the ZT-T120 is engineered for reliable fixed-wing and multi-rotor applications.
Product Details
ZT-T120 — Features & Engineering
Twin-Cylinder Two-Stroke Architecture
The ZT-T120 is built on a twin-cylinder, air-cooled, two-stroke platform with a bore of 45mm and stroke of 35mm, giving a total displacement of 120cc. The engine delivers 11.22hp (8.25kW) across a speed range of 1300 to 7500 rpm.
The three-ball-bearing crankshaft ensures smooth power transmission and long service life under continuous load. Mixture lubrication at a 25:1–30:1 ratio provides consistent cylinder wall protection throughout the operating range.
Automatic CDI Ignition — Carburetor or EFI
The automatic advance angle CDI ignition system optimises timing across the full speed range without manual adjustment. The system operates at 6.0–8.4V DC, compatible with standard airborne electrical systems.
The carburetor version consumes 4.5L/h, while the EFI version reduces consumption to 3.3L/h with more precise fuel metering. Recommended propellers are 26×10, 26×12, 27×10, and 28×10, selectable based on thrust requirements and installation configuration.
High-Output Performance at Altitude
At 100m altitude, the ZT-T120 produces 26.5kg of static thrust. At 1800m, it maintains 23.5kg — supporting platform designs up to 60kg maximum take-off weight across a wide range of operating elevations.
The engine is compatible with both push and pull propeller mounting configurations, giving aircraft designers flexibility in airframe integration. The 600W onboard generator provides dedicated power for avionics and payloads without affecting propulsion output.
