Engine Design

Twin-Cylinder Two-Stroke with Three-Bearing Crankshaft

The ZT-T170 is built on a twin-cylinder, air-cooled, two-stroke platform with a bore of 51mm and stroke of 41mm, delivering 170cc displacement and 18.1hp (13.3kW). The speed range spans 1100 to 7500 rpm.

The three-bearing crankshaft provides superior rigidity and load distribution compared to two-bearing designs, extending service life under continuous high-load operation. Mixture lubrication is set at a 50:1 ratio.

Ignition & Fuel

Automatic CDI Ignition — Carburetor or EFI

The automatic advance angle CDI ignition system optimises timing across the full rpm range without manual adjustment, operating at 6–8.4V DC.

The carburetor version consumes 6L/h. The EFI variant reduces consumption to 4.5L/h with improved altitude performance and more precise fuel metering. Recommended propellers are 30×12 and 32×10.

Performance & Thrust

High-Output Performance at Altitude

At 100m altitude the ZT-T170 produces 35kg of static thrust. At 1800m it maintains 31.5kg — supporting platform designs up to 80kg maximum take-off weight across a wide range of operating elevations.

Compatible with both push and pull propeller mounting configurations, the engine gives airframe designers full flexibility. The integrated 600W generator provides dedicated power for avionics and payloads without affecting propulsion output.

Frequently Asked Questions

ZT-T170 — Common Questions

What platforms is the ZT-T170 suitable for?

The ZT-T170 supports platforms with a maximum take-off weight of up to 80kg. Its twin-cylinder configuration and push/pull installation flexibility make it suitable for fixed-wing, agricultural, and medium-class multi-rotor aircraft.

What is the difference between the carburetor and EFI versions?

The carburetor version consumes 6L/h. The EFI version reduces this to 4.5L/h with more precise fuel metering and improved altitude performance. Both versions share the same engine block and mechanical components.

What propellers are recommended for the ZT-T170?

Recommended propellers are 30×12 and 32×10. Selection depends on platform thrust requirements and whether the engine is in push or pull configuration.

What crankshaft does the ZT-T170 use?

The ZT-T170 uses a three-bearing crankshaft, which provides enhanced rigidity and load distribution for reliable continuous operation under demanding conditions.

What ignition voltage does the ZT-T170 require?

The CDI ignition system operates at 6–8.4V DC. The automatic advance angle CDI adjusts ignition timing automatically across the 1100–7500 rpm operating range.
