1. Precision Inline 4-Cylinder DOHC Architecture 

Designed for exceptional mechanical balance and smooth power delivery, the ZT-1280CC adopts an Inline (L) 4-cylinder layout with 4 valves per cylinder (16 valves total). Driven by a high-efficiency Dual Overhead Camshaft (DOHC) valvetrain and featuring a 10:1 compression ratio, the engine optimizes gas exchange dynamics, providing a sustained maximum net power of 75kW and a stable piston linear speed of 15.77 m/s under continuous high-load flight regimes.

2. Advanced Multi-Point Injection & Fuel Flexibility 

Say goodbye to altitude-induced tuning issues. The engine integrates a sophisticated Multi-Point Electronic Fuel Injection system that meters fuel dynamically based on real-time atmospheric conditions. Optimized for high-altitude operational stability and superior fuel economics, it runs flawlessly on standard 92 Octane Gasoline (92#) while complying with stringent China V (国V) environmental emission standards.

3. All-Aluminum Alloy Construction & High-Torque Outputs 

To ensure an outstanding power-to-weight ratio without sacrificing structural durability, both the cylinder head and cylinder block are precision-cast from high-strength aluminum alloy. The engine exhibits a wide and robust torque band, generating a peak torque of 145N·m between 3500-4500rpm, ensuring remarkable climbing ability, prompt throttle response, and massive payload hauling capacity for fixed-wing cargo aircraft.
