Power vs. Torque – x-engineer

The torque T will be produce at the crankshaft on each conrod journal, every time the piston is in the power stroke.The lever arm a in this case is the crank radius (offset).. The magnitude of the force F depends on the combustion pressure within the cylinder. The higher the pressure in the cylinder, the higher the force on the crankshaft, the higher the output torque.
