SUMMARY
The torque moment diagram (TMD) of a 4-stroke engine exhibits a negative loop during the suction stroke due to the pressure differential created by the piston movement. As the piston descends, it increases the volume above it, resulting in lower pressure above the piston compared to atmospheric pressure. This phenomenon is critical for understanding engine dynamics and the functioning of the TMD, which illustrates the torque produced throughout the engine cycle.
