The dual cycle, also known as the limited pressure cycle or mixed cycle, is a gas power cycle that combines constant volume and constant pressure heat addition. It is commonly used in heavy-duty diesel engines, allowing for extended fuel burning time. Key moments: 00:01 Dual cycle, also known as limited pressure or mixed cycle, combines constant volume and constant pressure heat addition processes, making it suitable for heavy-duty diesel engines due to extended heat addition time and increased fuel burning efficiency. -Explanation of the processes in dual cycle including reversible adiabatic compression, constant volume and pressure heat addition, and isentropic expansion, crucial for engine efficiency. -Detailed explanation of the PV (pressure-volume) and TS (temperature-entropy) diagrams for the dual cycle, illustrating the compression, heat addition, and expansion processes graphically. 07:36 The video explains a thermodynamic cycle involving processes like constant pressure heat addition, isentropic expansion, and heat rejection at constant volume. The cycle is illustrated on PV and TS diagrams to show compression, heat addition, and expansion processes. -Illustration of isentropic expansion from points 4 to 5 with volume and pressure changes, showcasing the increase in volume and drop in pressure during expansion. -Explanation of constant volume heat rejection from points 5 to 1, leading to a drop in pressure and the rejection of heat at constant volume. -Demonstration of the thermodynamic cycle on TS diagram, highlighting isentropic compression, constant volume heat addition, and constant pressure heat addition processes. 13:49 The video explains the process of compression, heat addition, and expansion in an air cylinder, highlighting changes in volume, pressure, and temperature at different stages. -Compression of air from point 1 to point 2 involves reversible adiabatic compression, leading to a decrease in volume and an increase in pressure while keeping entropy constant. -During heat addition at constant volume from point 2 to point 3, pressure and temperature increase while volume remains constant, showcasing the relationship between pressure and temperature. -The process of constant pressure heat addition from point 3 to point 4 results in an increase in volume and temperature while pressure remains constant, demonstrating the impact of heat addition. 21:42 The video explains the working of a dual cycle, including heat rejection, efficiency calculation, and work output. It demonstrates processes through PV and TS diagrams, emphasizing efficiency calculation using heat supplied and work done. -Explanation of heat rejection during expansion and efficiency calculation based on heat added at constant volume and pressure. -Detailed calculation of work output by subtracting heat rejected from total heat added, emphasizing constant volume processes. -Efficiency determination by dividing work done by heat supplied, illustrating the concept of dual cycle efficiency calculation.

sir you are great!

[@joshuapancuelo1942]

Won't there also be work done during process 3 to 4?

[@poonamsen5664]

Thanks sir .....

[@SurajChauhan-wo1bv]

sir why have you deleted diesel cycle????

[@Balajianu5346]

Could I send me Atkinson cycle plz

[@AjitKumar-ym1tm]

Because bahut trouble ho raha h

[@mridulsharma1765]

kitniii ad????????????????????????
