Fuel System Requirements for Light Aircraft Turbocharged Reciprocating Engines

Due to the desire to fly light aircraft higher and faster, the turbocharged reciprocating engine has been developed. The turbocharger supplies more air to the engine at increased manifold pressure and temperature than a naturally aspirated engine can breathe, thus producing more horsepower. When different powers are selected from a turbocharged engine, manifold pressure and temperature changes occur very rapidly. Operating a turbocharged engine also produces problems in engine cooling and detonation.

The fuel system for the turbocharged engine, while similar to those on naturally aspirated engines, must be more intricate to compensate for the above mentioned conditions.
