What is torque in ic engine?

Torque in an internal combustion (IC) engine refers to the rotational force produced by the engine's crankshaft as it converts fuel energy into mechanical energy. It is a measure of the engine's ability to do work, influencing the vehicle's acceleration and overall performance. Torque is typically expressed in pound-feet (lb-ft) or Newton-meters (Nm) and varies with engine speed (RPM), peaking at specific RPM ranges for optimal performance. Higher torque values allow for better towing capacity and improved responsiveness in various driving conditions.
