What Does Torque Mean?
2 Answers
Torque is a special type of moment that causes an object to rotate. The details are as follows: 1. The torque of an engine refers to the moment output from the crankshaft end. Under fixed power conditions, it is inversely proportional to the engine speed—the faster the speed, the smaller the torque, and vice versa. 2. Torque reflects the load capacity of a car within a certain range. External torque is called external moment or external couple moment, while internal torque is called internal moment or torque. 3. For engines with the same displacement, higher torque indicates a better engine. Generally, the higher the torque of a car, the better.
I've always found the concept of torque quite fascinating. Simply put, it's the twisting force generated by the engine, typically measured in Newton-meters. It's like when you turn a doorknob - you need to apply some force to twist it open, and that force is similar to torque. In cars, you feel it most during acceleration, especially when the traffic light turns green. Vehicles with higher torque give that satisfying jerk forward. I've observed many cars climbing hills, and those with greater torque clearly handle it more effortlessly, avoiding that awkward situation where the engine roars but the car barely moves. However, torque is different from horsepower - torque is about explosive power while horsepower is about endurance, much like comparing a sprinter to a marathon runner. Anyone who's driven a diesel vehicle knows that high torque means both fuel efficiency and power.
