Lycoming Fuel Injection Systems

Product Type

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

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.
