Function Of Nozzle In Engine

This is the engine part which actually produces the thrust for the plane.

Hair dryer concentrator nozzle. In addition to the main nozzle in the venturi portion of the carburetor two other nozzles or ports deliver fuel to the engine cylinder. Choke valve is a valve that controls the mixture of air fuel. In a nozzle the velocity of fluid increases at the expense of its pressure energy.

Nozzles are frequently used to control the rate of flow speed direction mass shape andor the pressure of the stream that emerges from them. Cooling air is bled from the gas generator intermediate compressor stage to the power turbine first stage disk rim and nozzles. The nozzle turns the static high pressure high temperature gas into rapidly moving gas at near ambient pressure.

The power turbine rim cooling system is a series of pipes connectors flexible hoses drilled nozzle vanes and temperature probes. The injector hole is the final element of the fuel injection system before the fuel enters the combustion chamber. A rocket engine nozzle is a propelling nozzle used in a rocket engine to expand and accelerate the combustion gases produced by burning propellants so that the exhaust gases exit the nozzle at hypersonic velocities.

As such the size and shape of the nozzle hole can play a critical role in the emissions and performance of the diesel engine. A nozzle is often a pipe or tube of varying cross sectional area and it can be used to direct or modify the flow of a fluid.
