What Does Car Torque Refer To?
2 Answers
Car torque is the moment of force 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. This reflects the vehicle's load capacity within a certain range. Here is more information about car torque: 1. Definition of car torque: The reciprocating motion of the piston in the cylinder performs a certain amount of work per cycle, measured in Newton-meters. The work done per unit distance is the torque. 2. The driving force of a car can be calculated using the following formula: Torque × Transmission gear ratio × Final gear ratio × Mechanical efficiency.
When it comes to torque, I often encounter car owners asking about it at work. Simply put, torque is the rotational force generated by the engine—the kind of force that makes the wheels turn. It is measured in Newton-meters (Nm), and the higher the value, the more powerful the car feels during acceleration, like when it zooms off the moment the traffic light turns green. It also makes uphill driving easier without any sluggishness. If the torque is insufficient, the car feels underpowered, especially when carrying passengers or towing. In terms of maintenance, keeping the engine clean and changing the oil regularly ensures stable torque output. At high speeds, a good balance between torque and horsepower ensures smooth and fuel-efficient driving. In urban traffic jams, a high-torque engine responds quickly, reducing wear from frequent starts and stops.
