One Complete Cycle Four stroke internal combustion engine executes four complete strokes within the Cylinder while the crankshaft completes two revolutions for each thermodynamic Cycle while  Two stroke engine executes two complete strokes within the cylinder while the crankshaft completes One revolutions for each thermodynamic cycle. Main Strokes As the mane say fore stroke engine have four strokes Intake Stroke (Induction or Suction Stroke), Compression Stroke, Power Stroke (Combustion Stroke) and Exhaust Stroke  while two stroke engine only two stroke  First Stroke (Suction & Compression Stroke) and   Second Stroke (Power & Exhaust Stroke) Friction Losses Because of absence of valve tappets and crank shafts, friction losses are minimum in 2-stroke petrol engine as compared to 4 stroke engine Power D eliverance As mention above 2 stroke engine has less friction as compared to 4 stroke engine that's why have more power deliverance an compared to 4

Petrol Engine uses petrol as a fuel for combustion inside the cylinder. The petrol engine consist of a spark plug which ignite the air-fuel mixture (Air + Petrol). In petrol engine the carburetor prepare the require air fuel mixture Send it into the combustion chamber (Cylinder). Distance travelled between top dead centre and bottom dead centre is known as stroke.

Two stroke engine executes two complete strokes within the cylinder while the crankshaft completes One revolutions for each thermodynamic cycle. First Stroke (Suction & Compression Stroke):- In the first stroke the suction and compression processes take place simultaneously. The suction is done through port named inlet port and the movement of piston from bottom dead centre to the top dead centre causes the fuel to be compressed. Second Stroke (Power & Exhaust Stroke):- In the 2nd stroke the combustion and exhaust takes place. Due to combustion the piston moves downwards and the exhaust also takes place in the same stroke. During the exhaust the fresh charge also starts entering the engine cylinder. The designing of the top of the engine is such that the fresh charge does not combine with the expelling one. This is done by taking the term known as cross flow Two Stroke Engine working Starting from bottom the engine consists of a circular cylinder name
