What is the Automotive Bolt Torque Standard Reference Table?
1 Answers
It is necessary to consult the vehicle's maintenance manual or owner's manual and follow the manufacturer's specifications as the sole standard. For household passenger vehicles, the torque is generally 90-110N, which is approximately equivalent to a one-meter lever with 9-11 kilograms of force. Below is relevant information about automotive torque: 1. Definition and Explanation: Automotive torque is the moment output from the crankshaft end of the engine. 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 piston's reciprocating motion in the cylinder performs a certain amount of work per cycle, measured in Newton meters. The work done per unit distance is torque. 2. Calculation: Torque × Transmission gear ratio × Final gear ratio × Mechanical efficiency.
