I.C. engine:- The combustion is taking place inside cylinder is known as I.C. engine I.C. engine classification:- 1)Four stroke engine. 2)Two stroke engin e.

FOUR STROKE I.C. ENGINE :- “”The working cycle complete in four stroke is known as two stroke I.C. engine FOUR STROKE classification :- 1)Petrol engine. 2)Diesel engine..

 Many designs have been made over the last 4 centuries but only a few men were recognized as inventors.  The first person to invent a working internal combustion engine automobile was Francois Isaac de Rivaz of Switzerland in Mixing hydrogen and oxygen for fuel.  The first gasoline powered engine was built in 1864 by a man named Siegfried Marcus and was said to be the forerunner to the modern automobile.  In 1876 two of the greatest engines were invented. The two and four stroke engine by Nikolaus August Otto and Sir Dougald clerk. Starting the rise of even better and more efficient machine.

 This starts at the highest point known as top dead center and ends at bottom dead center.  The intake stroke allows the piston to suck fuel and air into the combustion chamber through the intake valve port.

 Compression starts at bottom dead center and ends at top dead center.  The second motion of the stroke takes all the fuel and air that was stored and compresses it into one tenth its original sizes. Making the air/fuel mixture increase in temperature preparing it for the next stage in its combustion cycle.

 The power stroke starts as soon as the piston reaches top dead center allowing the spark plug to ignite.  This electric current created by the spark plug ignites the fuel and air mixture sending the piston back down the cylinder with a high pressure.

 The final stage of the stroke releases all the burned fuel through the exhaust valve.  As the piston moves from bottom dead center to top dead center it takes all the burned fuel and pushes it out of the cylinder, preparing it for the next cycle of strokes.
