Lycoming Fuel Injection Systems

Product Type

All RSA type fuel injection systems are based on the principle of measuring engine air consumption by use of a venturi and the resulting airflow forces to control fuel flow to the engine.

The metered fuel is delivered by the injector to a pressurized flow divider which distributes the fuel to the individual cylinders via dedicated lines and nozzles. The flow divider is a simple spring-loaded valve that is sealed to atmosphere by a diaphragm.

The fuel discharge nozzles at the cylinder each contain a calibrated jet that is sized according to the system flow requirements of the engine.
