Ahh...
Adiabatic compression - I squeeze you until you can take no more!
Heat addition at constant volume - You generate more heat in your posts...
Rejection of heat at constant volume - we keep posting until the thread blows itself out...
The two additional processes complete my cycle....
Exhaust of waste heat... the arguments are exhausted, insults traded...
The intake of of cool, oxygen-rich air... we start again in another thread...
But, you are only a reciprocating engine with huge friction and mass-acceleration losses, I do it with gas turbines - greater effectiveness, less weight and enormous power-to-weight ratios!!!
Merry Christmas piston-engine man, from your friend the gas-turbine.
