Welcome back MechanicalEI, Did you know that, Almost all modern hybrid electric drive train vehicle makes use of the Atkinson cycle to provide initial start and that the Brayton cycle is what powers those jet engines? This makes us wonder, What are Atkinson and Brayton Cycles? Before we jump in check out the previous part of this series to learn about what Stirling and Ericsson Cycles are ? Now, The Brayton cycle consists of four processes. Process 1 is an isentropic process where in ambient air is drawn into the compressor and pressurized. In Process 2 the compressed air then runs through a combustion chamber, where fuel is burned, heating that air— which is a isobaric process, since the chamber is open to flow in and out. Process 3 is an isentropic process wherein  the heated, pressurized air then gives up its energy, expanding through a turbine (or series of turbines). The final process is an isobaric process wherein heat is rejected to the atmosphere. Next is an Atkinson  cycle there are 6 processes. Processes 1 is an isentropic compression, process 2 is isochoric heating. Process 3 is isobaric heating. Process 4 is isentropic expansion. Process 5 is isochoric cooling and  Process 6 is isobaric cooling. Hence, We first saw what the Atkinson Cycle is and then went on to see what the Brayton cycle is?
In the next episode of MechanicalEI find out What Combustion is?
