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) Wian T₁ Tc.in Te, out Ta Texh Reciprocating IC engine Control surface Write the general energy equation for the system.
