Adiabatic temperature drop from work.during expansion, becomes adiabatic temperature increase during the return stroke And uses the same amount of work to accomplish the compression.
Only heat rejection will reduce the work requirement for the return stroke below the power stroke.
Why must you continually jack up even simple stuff ???Tom Booth wrote: ↑Sun Aug 18, 2024 11:14 am "Adiabatic" only means there is no heat transfer. Cooling during adiabatic expansion can be the result of both the expansion work itself AND additionally any work the engine is performing; turning the crankshaft, overcoming friction and driving any additional load
All of those work outputs result in additional cooling above and beyond the minimal cooling from gas expansion with zero load, no friction of atmospheric pressure or other resistance.
There's this thing called the heat capacity of a gas which you obviously don't grasp. The adiabatic work doesn't care where it goes, but any work 'subdivisions' can only equal the total work of the gas process.
Tom, you need a new hobby, Fool has it right.
