3. The following figure depicts a thermodynamic model for a reciprocating internal combustion

engine with the control volume shown by the dashed line. The heat losses by heat transfer from

the hot engine surfaces can be assumed negligible. (T represents the temperature of the flow

going in/out of the control volume and W represents the work transfer between the control

volume and the environment)
