Valve timing diagram samja o ge sir
Sir last comparison was wrong .... You said 4-stroke engine was simple and easy manufacturing... But actually sir 2-stroke engine is lighter and simple construction then 4-stroke engine.
in two stroke engine if inlet valve is closed at first than how charge is available inside the cylinder

Firstly there are no valves used in 2 stroke in engine and there is a lot of charge is present below the volume of the piston which is get transfers through transfer port , please,see the diagram carefully.
sir power kisme jada generate hoti hai

  8. 4 -Stroke Engine 2 -Stroke Engine er heavier engine. For the same pow is required. More Volumetric efficiency More thermal efficiency For the same power lighter engine is . required. . less Volumetric efficiency less thermal efficiency Ex : scooters, mopeds , ships Ex: motorcycles, cars, buses, trucks, aeroplanes, power generators.


  9. 4 -Stroke Engine 2 Stroke Engine Less toxic exhaust emissions Very high and toxic exhaust . . emissions 720 degree crank revolution 360 degree crank revolution. . Simple and easy manufacturing Complex and tough manufacturing . .
