Engine Architecture

Four-Cylinder Two-Stroke with High Compression

The ZT-T222 uses a four-cylinder, air-cooled, two-stroke layout. With a bore of 45mm and stroke of 35mm delivering 222cc displacement, it produces 20.9hp (15.3kW) at a compression ratio of 7.6:1.

Idle speed is 1000 rpm. Mixture lubrication is set at a 30:1 ratio. The four-cylinder configuration provides inherent balance, smoother power delivery, and reduced vibration compared to twin-cylinder alternatives.

Ignition & Fuel

Automatic CDI Ignition — Carburetor or EFI

The automatic advance angle CDI system operates at 4.8–8.4V and continuously adjusts ignition timing for optimum performance. Specified spark plug is NGK CM6.

Carburetor fuel consumption is 8.3L/h. The EFI version reduces this to 6.2L/h with improved metering and altitude stability. Recommended propellers are 32×10, 32×12, and 34×10.
