 Impulse turbine   It is the convert the hydraulic energy of water into the mechanical energy  Working of it :  In this turbine required the hydraulic head which produce the hydraulic energy that energy is impact on the blade of impulse turnine so impulse wheel is rotate that rotation is called mechanical energy   As shown in below figure  

        Hydraulic   Turbine   Turbine is the mechanical device which convert the hydraulic energy of water into the mechanical energy that is called hydraulic turbine.             Its is generally used in  hydraulic power plant  , for producing electrical energy  It is two types  1. Reaction turbine  2. Impulse turbine 

Engine   Engine is mechanically device which convert the chemical energy of fuel  into the mechanical energy that is called engine.  There are two types of engines  1. Internal combustion engine  :  Fuel is burn inside the cylinder  that is called ic engine.  2. External combustion engine :  Fuel is burn outside the cylinder 

  Working of ic engine   In diesel engine :  It's cycle complete in four stroke   Suction stroke :   only Air is inter in cylinder  when piston is move  in TDC  so suction stroke is produce.  Compression :  Sucked air is compressed inside the cylinder so produce high temperature and pressure  in combustion chamber.  Expension stroke :  After the compressed air, diesel is spray by injector In small drops form.  Generate the high power of combustion,So expand the  flue gases  and push the piston with great force so piston is move .  Exhaust stroke :  Removing of flue gases from the combustion chamber. 

  Working of internal combustion :  In petrol engine :  Suction stroke :  piston moves in  TDC  so vaccum is generate . Then The mixture of fuel and air  (in carburetor)is sucked in cylinder  .  Compression stroke :  The mixture of air and fuel is compressed in cylinder up to high temperature and pressure.  Expension stroke :  Compressed mixture is ignited by spark plug  so then expand the flue gases in cylinder and push the piston by great force. That stroke is called power stroke. Because power generate in this stroke.  Exhaust stroke :  After expension of flue gases  then remove the flue gases from the  combustion chamber.

  Thermostat valve :   Thermostat is a valve between the engine and the radiator. It's crucial because it helps the engine stay within a safe operating temperature. It's work is to respond to temperature changes in the engine coolant. When the coolant in the engine block gets too hot, this valve opens letting coolant pass to the radiator where it will cool down. When cold, the thermostat stays closed, allowing the coolant to continue circulating inside the block. (Inset:engine thermostat) #MechanicalEngineering Mech study point
