Product Overview
The ZT-1280CC is an automotive-grade, highly reliable aviation piston engine with a displacement of 1280 mL (1.28L), featuring an inline 4-cylinder naturally aspirated design. It is purpose-developed for next-generation heavy-lift industrial UAVs, cargo delivery drones, and light experimental aircraft.
Combining a precision Dual Overhead Camshaft (DOHC) valvetrain, 4 valves per cylinder, and an advanced multi-point electronic fuel injection (MPI) system, this power unit achieves excellent thermal efficiency and consistent power delivery. Built entirely with high-strength aluminum alloy, it sets a high standard for fuel economy and operational reliability in high-end commercial aviation applications.
Core Performance Features
1. Precision Inline 4-Cylinder DOHC Valvetrain
Engineered for exceptional mechanical balance and smooth, linear power delivery, the ZT-1280CC adopts an inline (L-type) 4-cylinder layout with 4 valves per cylinder (16 valves in total). Driven by a high-efficiency DOHC valvetrain and paired with a 10:1 compression ratio, it optimizes intake and exhaust gas exchange efficiency. The engine sustains a maximum net power of 75kW with a stable piston linear speed of 15.77 m/s, maintaining reliable performance even during extended high-load flight operations.
2. Multi-Point Electronic Fuel Injection for Stable Altitude Performance
The engine integrates a sophisticated multi-point electronic fuel injection system that dynamically meters fuel volume according to real-time atmospheric and altitude conditions. This design eliminates the need for manual tuning when operating at different elevations, ensuring consistent combustion and stable power output. Optimized for high-altitude operational stability and superior fuel efficiency, the engine runs smoothly on standard 92# octane gasoline and meets stringent China V emission regulations.
3. All-Aluminum Lightweight Construction & Broad Torque Band
To deliver an exceptional power-to-weight ratio without compromising structural rigidity and durability, both the cylinder head and cylinder block are precision-cast from high-strength lightweight aluminum alloy. The engine features a wide and robust torque output band, reaching its peak torque of 145N·m between 3500rpm and 4500rpm. This torque characteristic ensures responsive throttle feedback, reliable climbing performance, and strong payload carrying capacity for fixed-wing cargo and industrial drone platforms.
