comparison between 2stroke and 4stroke engine

 difference between 2stroke and 4stroke

Fore stroke engine

1. valve system is used
2. it is costly
3. the compression ratio of air is less because of that it gives the less thermodynamic efficiency
4. having more volumetric efficiency
5. it having less weight
6. it is complicated to design
7. used in lightweight working at very high speed and where the energy is less required or less power consumption is required this type of application
8. it having less compression ratio
9. it works on Otto cycle or usually called petrol cycle
10. at each 4 stroke it get only one power Store

  

two stroke engine

1. the port system is used
2. it having less cost
3. it having greater compression ratio because of that thermodynamic efficiency is very great
4. volumetric efficiency is less
5. due to high compression ratio we required the strong cylinder because of that weight of engine is increases
6. it is very simple to design
7. it is used in any machine where the more power consumption measurement of power consumption is required like drugs and heavy artillery guns
8. it having more competition ratio
9. it is used in diesel cycle
10. at each two stroke we get one power stroke
