Internal Combustion ( I.C. ) Engine , Classification of I.C. Engine

      -: Internal Combustion (I.C.) Engine :- 

An heat engine , in which the combustion of fuel in the presence of air takes place inside the cylinder and produced gases act on piston to develop the power is known as I.C. Engine .

    -: Classification of I.C. Engines :- 

I.C. engines are classified as follows - 
1- According to the cycle of Operation :- 
                                                                    According to the cycle of operation the I.C. engine are of two types - 
(i)- Four stroke engines
(ii)- Two stroke engines 

(i)- Four Stroke Engines - In this type of engines cycle is completed in two revolution of crank .
(ii)- Two Stroke Engines - In this type of engine cycle is completed in one revolution of crank . 

2- According to the nature of Thermodynamic cycle :- 
                                                                                       According to the nature of thermodynamic cycle there are three types - 
(i)- Otto Cycle Engines 
(ii)- Diesel Cycle Engines 
(iii)- Dual Cycle Engines 

3- According to Method of Ignition :- 
                                                             According to the method of ignition there are two types of engine - 
(i)- Spark Ignition (S.I.) Engines 
(ii)- Compression Ignition ( C.I. )
(i)- Spark Ignition ( S.I.) Engines -  

                                                        In this type of engines air - fuel mixture supplied by carburetor is ignited by producing spark . It is also called petrol engine .  

(ii)-Compression Ignition (C.I.) - In this type of engines air is compressed to higher pressure and in fine atomised form fuel is injected in combustion chamber . Hence air- fuel mixture is ignited without producing spark . It is also called Diesel Engines . 

4- According to Number of Cylinders :- 
                                                                 According to the number of cylinders there are two types of engines - 
(i)- Single Cylinder Engine 
(ii)- Multi Cylinder Engines 


5- According to the type of Cooling System :- 
                                                                   According to the  type of cooling system there are two types of engines -
(i)- Air Cooled Engines
(ii)- Water Cooled Engines
(i)- Air Cooled Engines - 
                                      In which engines , normal air is used for cooling purpose is known as air cooled engine . 
(ii)- Water Cooled Engines - 
                                                In which engines , water jacket is used around the cylinder for cooling purpose , is known as water cooled engine . 

6- According to Speed of Engine :- 
                                                                             According to the speed of engine there are three types of engines - 
(i)- Low Speed Engine 
(ii)- Medium Speed Engine 
(iii)- High Speed Engine 

7- According to the lubrication method :- 
                                                                                          According to the lubrication method there are three types of engines -
(i)- Wet Sump Lubricating Engine
(ii)- Dry Sump Lubricating Engine 
(iii)- Pressure Lubricating Engine 

8- According to the Fuel used :- 
                                                                      According to the fuel used there are three types of engines - 
(i)- Petrol Engine 
(ii)- Diesel Engine 
(iii)- Gas Engine 

9- According to the Field of Operation :- 

                                                             According to the field of operation there are four types of engines - 
(i)- Automotive Engines 
(ii)- Stationary Engines 
(iii)- Locomotive Engines 
(iv)- Marine Engines 

10- According to arrangement of Cylinder :-  
                                                                 According to the arrangement of cylinders there are seven types of engines - 
(i)- Vertical Engine
(ii)- Horizontal Engine 
(iii)- V-Engine 
(iv)- W-Engine 
(v)- Radial Engines 
(vi)- Opposed Cylinders Engines 
(vii)- Opposed Piston Engines 

(i)- Vertical Engine - 
                                   In which engines , cylinder is in vertical position , is known as vertical engine . 

(ii)- Horizontal Engine - 
                                        In which engines , cylinder is in horizontal position is known as horizontal position . 

(iii)- V-Engine - 
                          In which engines , two cylinders are arranged at an angle connected to a common crank is known as V-Engine .

(vi)- Opposed Cylinder engine - 

                                                     In which engines , cylinders are arranged on opposite side of a common crank , is known as opposite cylinder engine .
