Engine Governor

                  Engine Governor

                Every time engine has not same load. But different time different load on the engine. But vehicle required same speed during running the engine. Therefore flywheel use to constant speed provide to the engine.
           
Types of Governors

                Therefore Governor is use. Governor is a type of mechanical device which is generally used to determine and regulate the speed of the engine to the desired level. It is a particular feedback system used where is the need to control variation of load present in the system. When the load of an engine increases the speed of engine decreases and vice versa when the load on the engine decreases speed of the engine. Governor is play very important role in fluid control system.

Types of Governors :


1) centrifugal Governor :


   • Pendulum type
     a) Watt Governor

   • Gravity Loaded
    a) Porter Governor
    b) Proell Governor

   • Spring Loaded
   a) Hartnell Governor
   b) Wilson Hartnell Governor
   c) Hartung Governor
   d) Pickering Governor

2) inertia Governor


Working of Governor :

     When engine load increase than Governor rotation speed also increase than flow of fluid speed also increase hence it gives high flow fluid to the engine and maintain the speed.
     
     When engine load decrease than Governor rotation speed also decrease than flow of fluid speed also increase hence it gives low fuild to the engine and maintain the speed.

Turbocharger | Supercharger

                    Supercharger

                     Increase efficiency of the internal combustion engine by increase the compression ratio. And increase compression by increase flow of air density. Supercharger is device which increase the density of air before air go to the combustion chamber. Supercharger increase compression ratio. Therefore Supercharger is increase the efficiency of the internal combustion engine. Supercharger increase air supply to the engine.

How to work Supercharger ?

              Supercharger is device which increase the air density which give to the engine. Supercharger is air compressor which connected to the internal combustion engine and take air from atmosphere. Air compressor rotate by internal combustion engine. Atmospheric air compress into the compressor. The compressed air go to combustion chamber. The air go to into the combustion chamber which air density high which increase the combustion and therefore it increase the efficiency of the engine.

But there is some disadvantages of the supercharger are below :

• The compressor take power from internal combustion engine therefore it reduce some power of the engine. 
• Its initial cost is also high therefore it is not use in small car.


                      Turbocharger

Supercharger

            From some disadvantages of the supercharger we use turbocharger in the vehicle. Turbocharger is one type of supercharger. Turbocharger is give high efficiency compare to Supercharger. 

How to work turbocharger ?

       In Turbocharger turbine is connected to the exhaust of the internal combustion engine when exhaust gases out from the engine which rotate the turbine and turbine is connected to the compressor. Compressor is rotate by turbine and compressor is compress the atmospheric air give to internal combustion engine. It increase the efficiency of the engine.

     Turbocharger use in heavy car. It is not use in small car because its cost is high.

4 stroke diesel engine | 4 stroke petrol engine

               Four stroke engine


Four stroke engine


              Now day every engine is four stroke but previous time use to two stroke engine. Four stroke engine is high efficient compare to the two stroke engine. Four stroke engine has more advantages comparer to the two stroke engine. In four stroke engine does not require fuel mix with oil. Four stroke engine complete one cycle in four stroke. Four stroke same in petrol and diesel engine but some difference in ignition process. 

How to work four stroke petrol and diesel engine ?

There are four stroke available in four stroke petrol and diesel engine.
1) Intake stroke
2) Compression stroke
3) Power stroke
4) Exhaust stroke

1) Intake stroke :

In intake stroke pressure difference between atmospheric pressure and inside cylinder pressure the intake valve open therefore fuel and air  go into the cylinder in petrol engine and when fuel go into the cylinder in diesel engine piston move TDC ( Top Dead Centre) to BDC ( Bottom Dead Centre). In intake stroke exhaust valve close. After intake stroke intake valve close.

2) Compression stroke :

In compression stroke both intake valve and exhaust valve close. During compression stroke piston goes to TDC ( Top Dead Centre) to BDC ( Bottom Dead Centre). Then fuel will be compress. 

3) Power stroke :

In power stroke both intake and exhaust valve close. During Power stroke the compress fuel is ignited by spark plug in petrol engine and when hot air gases ignite fuel in diesel engine. In power stroke after ignition the piston move from TDC (Top Dead Centre) to BDC ( Bottom Dead Centre). In this stroke power is produce.

4) Exhaust stroke :

After power stroke fuel gases produced. It required to remove them out of the engine. In exhaust stroke due to pressure difference between cylinder and atmospheric pressure the exhaust valve open and fuel gases out of the cylinder. During exhaust stroke intake valve close. After exhaust stroke crankshaft take one revolution.

Piston engine | Types of engines

                    Piston engine 


                 There are so many car available in the world. Different car has different type of engine. Therefore, it produces different power of the car. Here types of engines according to Piston arrangements in the engine are below.

Types of engines according to Piston arrangements in the engine :

1) Inline engine
2) V engine
3) W engine

1) Inline engine :

Types of engines


               An inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, but rarely more than six.

              An inline engine take more space compare to the v engine. Therefore, it required large space to produce more power. Therefore, inline engine use only small car which requires less power.

2) V engine :

Type of engines

                A V engine, is a common configuration for an internal combustion engine. The cylinders and pistons are aligned, in two separate planes or banks, so that they appear to be in a 'v' when viewed along the axis of the crankshaft.

              A V engine is take less space compare to inline engine. Therefore, it required less space to produce more power. Therefore, V engine use in heavy car where requires large power. In V engine has 6 or more piston.

3) W engine :

Types of engines



             A W engine is a type of reciprocating engine arranged with its cylinders in a configuration in which the cylinder banks resemble the letter W, in the same way those of a V engine resemble the letter V.

           A W engine is take very less space compare to V and inline engine. Therefore, it required less space to produce more power.  W engine design is very compicacomp therefore its use very less car engine.
