Torque is an important parameter of engine performance, which refers to the average torque output from the crankshaft end during engine operation. The greater the torque, the greater the“Force” of the engine output, the faster the change of the crankshaft speed, the better the vehicle's climbing ability, starting speed and acceleration. The torque varies with the speed of the engine. If the speed is too high or too low, the torque is not maximum. There is a maximum torque only at a certain speed or within a certain speed range, this is the speed or speed range given when the maximum torque is marked. The maximum torque usually occurs in the range of middle and low speed of the engine, but will decrease with the increase of speed. Torque is measured in Newton meters (n meters) or kilograms (kg meters)
The maximum torque of the engine is related to the design of the intake system, fuel supply system and ignition system of the engine. In addition, the engine power, torque and speed are related, the specific relationship is: power = k × torque × speed, where k is the conversion coefficient. When choosing an engine, consider how to use it properly and not waste existing features
