AIR STANDARD CYCLE

Image
  AIR STANDARD CYCLE:   OTTO CYCLE: Nicholus august otto is invented a working four stroke diesel engine,that’s why the four stroke cycle is also known as otto cycle.later this formula is widely used in petrol engine too. Otto cycle is an idealized thermodynamic cycle that explain about the function of typical spark ignition piston engine.it widely used in automobile engine. In this system describe what happens to mass of air? And how it changes due to pressure,volume,temperature,addition of heat,removal of heat. PROCESSES: Process 0-1 = intake stroke,mass of air is drawn into cylinder at constant pressure. Process 1-2 = isentropic compression stroke,to compress the air/fuel ratio the piston moves BDC(bootom dead center) to TDC(top dead center). Process 2-3 = constant volume heat addition,due to the compression,the air fuel mixture burns rapidly and it will produce massive heat while the piston stay at TDC. Process 3-4 = isentropic expansion,the power, the piston is driven out...
