• High power 17.5 hp with a small working volume of 120 cm³.

• Record low weight of only 3200 grams for a two-cylinder engine.

• The two-cylinder design ensures smooth operation and low vibrations.

• Excellent thrust up to 26.5 kg at low altitudes with economical consumption.

• Low idle speed of 1300 rpm for stable operation.

Operating principle and design features

The AM-120 engine operates on a classic two-stroke cycle. The fuel mixture of gasoline and oil enters the crank chamber. From there, through the bypass channels, it enters the cylinders. The spark plug ignites the compressed mixture in the combustion chamber. The two cylinders work alternately, creating uniform torque.

The two-cylinder design provides serious advantages over single-cylinder analogues. Vibration levels are significantly reduced throughout the entire speed range. The engine runs softer and smoother, increasing its service life. Air cooling ensures simplicity and light weight. Compact dimensions allow you to place the motor in limited space.

Specifications and performance

Study the exact parameters of the AM-120 engine. Maximum power reaches 17.5 horsepower. It develops at 7500 rpm. The engine displacement is 120 cubic centimeters.

Idle speed is 1300 rpm. This ensures stable operation on the ground during launch. Traction characteristics depend on flight altitude. At an altitude of 100 meters the thrust is approximately 26.5 kilograms. At an altitude of 1800 meters, the thrust decreases to 23.5 kilograms.

The engine weight is only 3200 grams. This is an excellent indicator for a two-cylinder engine of this power. The engine requires the use of high-quality fuel. High octane gasoline mixed with oil in the correct proportion is recommended.

Areas of application and operation

The AM-120 engine is ideal for medium-class unmanned aerial vehicles. It is widely used in aircraft-type UAVs and heavy-duty multicopters. Used in agricultural drones for spraying fields. Suitable for high-end sports and hobby aircraft models. This is the choice for those who value high power density.

A high-quality fuel system is required for operation. Use a reliable fuel tank with a filter and ventilation. Select the correct propeller for the characteristics of the motor and model. Run in the new engine according to the manufacturer's instructions. Regular maintenance will ensure a long service life.
