To calculate torque versus crank angle for a Wankel engine, determining the pressure values p1, p2, and p3 is crucial. The application of the PV diagram for an ideal cycle may not directly apply to a Wankel rotary engine due to its unique design. While the four strokes are conceptually similar to those in a piston engine, the three-chambered rotary engine requires specific assumptions that differ significantly. Accurate pressure values can be derived from experimental data or simulations tailored to the Wankel engine's characteristics. Understanding these nuances is essential for effective torque calculations in this type of engine.
