Torque Introduction
Torque sensor Torque, like power, is one of the main indexes of a car engine, and it is reflected in car performance, including acceleration, gradeability, and suspension. Its exact definition is: the reciprocating motion of the piston in the cylinder, there is a certain amount of work done in one reciprocation, and its unit is Newton. The work done per unit distance is torque. This is the case, torque is an important criterion for measuring the quality of a car engine, and the magnitude of a car's torque is proportional to the power of the engine.
For example, when the human body is in motion, power is like the endurance of the body, and torque is the explosive force of the body. For a family car, the greater the torque, the better the acceleration; for an off-road vehicle, the greater the torque, the greater the grade; for a truck, the greater the torque, the greater the weight of the car. In the case of the same displacement, the higher the torque, the better the engine. When driving, you will feel that the car can do whatever you want, you can accelerate if you want, and the "back feeling" is very good. An important data to evaluate a car now is the acceleration time of the car at 0-100 km/h. And this acceleration time depends on the torque of the car engine.
Generally speaking, the highest index of torque can be achieved at the speed of 2000-4000/min of the car, which means that the engine of this car is better in craftsmanship and strength. Some cars only reach the highest index of the car's torque at around 5000/min, which shows that "power" is not the car's strength.
Torque Overview
Torque is the force that makes an object turn. The torque of the engine refers to the torque output by the engine from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range.
In some situations, it really reflects the "true color" of the car, such as when starting or driving in the mountains, the higher the torque, the better the response of the car. Compared with the same type of engine car, the larger the torque output, the larger the bearing capacity, the better the acceleration performance, the stronger the climbing force, the less the number of shifts, and the less wear and tear on the car. Especially when the car starts at zero speed, it shows the superiority of the one with the higher torque to increase the speed faster.
How to express engine torque
The expression method of engine torque is Newton-meter (N.m). Like the power, the revolutions per minute (r/min) is generally indicated along with the maximum output torque of the engine. The maximum torque generally appears in the range of medium and low speed of the engine, and as the speed increases, the torque will decrease instead.
