What Does Maximum Torque Mean?
2 Answers
Maximum torque refers to the twisting force generated by the engine crankshaft. For vehicles with the same transmission ratio, greater torque means more power. Maximum power is the work done by torque and rotational speed per unit time. Under fixed power conditions, it has an inverse relationship with engine speed - the faster the speed, the smaller the torque, and vice versa, reflecting the vehicle's load capacity within a certain range. The engine's maximum torque is related to the design of its intake system, fuel supply system, and ignition system. The engine's power, torque, and rotational speed are interrelated, with the specific relationship being: power equals the product of conversion coefficient, torque, and rotational speed.
Maximum torque is the maximum rotational force a car's engine can produce. I think of it as the engine's muscle power - the greater it is, the stronger the force. For example, when overtaking or climbing hills, stepping on the accelerator allows this force to propel the car forward faster. This is usually measured in Newton-meters, and the power delivery point may vary at different RPMs. Generally, diesel vehicles can produce substantial torque at low speeds, making them well-suited for hill climbing. When I was first learning to drive, I test-drove a high-torque vehicle and felt its powerful performance - hauling loads up mountains was effortless. Understanding this has greatly helped my daily driving. When choosing a car, I now look at torque specifications since it directly relates to acceleration feel, unlike horsepower which represents sustained power at high RPMs.
