Overview
The UAV-170 engine based on the Fiala PROP. company FM 170 B2 – FS power plant is a 4-stroke gasoline motor with volume 170 ccm designed for being integrated in UAV.
It is a 4-stroke propulsion system with OHV and 2 valves per cylinder. The engine is equipped with a microprocessor ignition for easy starting and smooth running in all modes of engine speed.
The power plant has been modified by UAVOS to improve performance :
— Air cooling and a two-nozzle fuel injection system have been made.
— A brushless generator-starter is installed on the engine.
UAVOS's injection system can be very precisely tuned with a lambda probe depending on the operating conditions.

Engine Control Unit
Engine is equipped with Engine Control Unit (ECU) UV01.6401.06.63.00.
This unit is intended for processing information from sensors:
— calculates the optimal amount of the fuel input;
— determines the moment of ignition (based on the operating conditions of the engine and its mode).
The unit is equipped with a digital data line, which allows the flight controller to transmit sensor readings, as well as receive ignition commands and gas levels.
The main functions of the Engine Control Unit (ECU) UV01.6401.06.63.00:
— adjustment of the amount of fuel input;
— ignition timing adjustment;
— power supply control of the fuel pump;
— temperature measurements EGTх2, CHTх2, AT;
— the formation of control pulses of the gas servo drive;
— data exchange with a software navigation system.
