What is Engine Torque? It's Characteristics & Formula

Peak vs. Flat Curve Torque. Most modern diesel engines deliver a ' flat-curve ' torque. In 'flat-curve' design, the motor produces maximum torque at a ' lower-to-middle-end ' of its speed, i.e., approx. 1500 rpm onward. Its value remains almost the same or 'flat' across most of the engine speed ranges (2500-4000 rpm).
