Stirling engine is a kind of heat engine.Which is used in the vehicle's internal combustion engine
Completely different.In 1816 this engine was inventedby Robert Sterling.. The efficiency of the Sterling Engine is much more than gasoline or diesel engines
Its use is limited in some special cases even though it is high, Such as submarine, power supply for light ships etc.Although successful marketing of the Sterling Engine is not yet possible, its of course
Many research and development work is going on.Sterling Engine "Stirling Cycle"
Which works through, which is different from the intensive engine cycle.
The gas inside the engine
(working fluid)
which never removed.There is no emission valve.There is no gas explosion inside the engine. As a result, the Sterling Engine does not produce any sound.Cycle is the use of an external heat source
, Which can be anything from gasoline to solar heat. Engine cylinders,
There is no burning process inside.

The Ideal Sterling Cycle is organized on four processes of thermodynamics.

1-2 process: Isothermal expansion

2-3 Process:constant volume heat rejection

3-4 Process:Isothermal compression

4-1 Process:Constant volume heat addition

One inside the Sterling Engine
The cylinder is filled with a certain amount of gas in the air
Two special features of gas are used.

• If there is no specific amount
  With the addition of its pressure as well as its heat, keeping the gas in place of a certain volume
  Will increase.
• If there is a specific amount
  Increasing its pressure in place of gas in place of a certain volume, its heat and simultaneously.

Stunning engines only
Process produces power at 1-2. This power generation can be increased in two ways.

1. Power in process 1-2 Increase production:
   Here the pressure of the warm gas pushes the piston upwards, so the work is done
   If this pressure is increased, then the energy production will increase. And this is
   Increase the pressure can increase the temperature.
2. Process 3-4 reduces energy use:
   Here's the piston process
   Use a part of energy generated in 1-2 to complete the work on gas. If used
   The amount of this energy can be reduced, but if the power generation is increased, the pressure will be reduced here
   Energy can be used. If the gas is already cooled down and the temperature is reduced
   The pressure will be reduced.

Here is the ideal sterling
The engine was described, but the actual Sterling Engine operation
Because of the physical structure, it becomes a little different.

Different types of sarlings engine

Sterling engines are usually 2 types.

• Alpha
  Sterling
• beta Sterling.

1. Alpha Sterling or two piston stellings engine

Two in Alpha Sterling Engine
There is a separate cylinder and each cylinder has a piston. A
Warm piston and a cool piston. The warm piston cylinder has high temperature
The cool piston cylinder inside the hit exchanger and the cooler heat exchanger
Inside The power and volume ratio of this engine is much higher but the warm piston have
Some technical problem in cylinders with high temperatures and cylinders.

Most of the gas here is warm in
The cylinders are high and the high temperature here increases the size of the gas and
Pull the warm piston outside the cylinder. This volume of gas cools down the extension
The cylinder continues, which is 90 degrees behind the hot cylinder and behind
Work from warm gas.

Here's the maximum volume of gas
And the warm cylinders are pushing the piston gases towards the cooler cylinder. Cooler
Due to the cylinders the gas cools down and the area is compressed.

Most gas cools here
The cylinders tend to be cool. Flihohill's speed control of this piston tour
Do it.

Here the gas volume is the lowest
And then the gas is hot again in the warm cylinder and the same process continues over and over again
Remains.

2.Bita Sterling or

Sterling Engine with Displaceer

It has only one cylinder
And there are two pistons, one of which is the display piston another
Piston Displaceer piston is loosely fixed and no gas is available
Power does not absorb, but rather gas from the hot hit exchanger to Cool Heat Exchanger
Helps to go. Get it when the gas cylinder goes to the warm end
It pushes the piston and when it goes to the cool end it collapses. And the whole
The process is controlled through flyhills. In the beta engine the airtight
There is no technical problem.

Power piston compressed gas
And the help of the displacement piston gas to the edge of the warm hit exchanger
Do it.

Inside the hot gas cylinder
Increases pressure and pushing the power piston upwards. It is a power stroke.

Displacer engine full
Went down and forced the gas to move upwards.

Why usually the Sterling Engine Not used?

The main reason is external
Thermal source. The engine takes some time to respond to the heat cylinder, because the engine takes some time to respond to heat
The exposure of the external heat cylinders to the gas in the engine is in contact with the gas
It comes, which can be quite time consuming.
. That means

The engine
Before the power generation, the engine will take some time to heat.and its
Power generation can not be changed.
Use of Sterling Engine

Sterling in different areas
Engines are used, such as incorporated heat and power generation, solar power generation, hit pumps,
Marine engines, molecular power, car engines, aircraft engines etc.
Dr. Dr. L. Marrick Lockwood Sterling in the early 80s
The engine is made, it is used for paddy crushing. And the thing about glory is that it is one of the top ten uses of the Sterling Engine.
