What is Torque?
2 Answers
Torque refers to the rotational force of a car, which is the moment output from the crankshaft end of the engine. The engine is the device that provides power to the car, determining its power performance, fuel economy, stability, and environmental friendliness. Based on its working principle, engines can be categorized into: 1. External combustion engine: Fuel burns outside the engine; 2. Internal combustion engine: Fuel burns inside the engine; 3. Gas turbine: Uses high-pressure gas to drive the turbine blades for power output; 4. Jet engine: Generates thrust directly by the high-speed jet of gas from the nozzle. Precautions for engine maintenance include: 1. Using high-quality engine oil for lubrication, cleaning, cooling, sealing, and wear reduction; 2. Using qualified coolant; 3. Regularly cleaning the radiator scale; 4. Periodically removing carbon deposits from the car; 5. Timely replacement of the car's three filters.
Torque in physics is essentially rotational force, simply put, the ability to make an object rotate. In automotive engines, it directly determines a vehicle's initial pulling power—step on the accelerator, and the torque output from the engine drives the wheels, giving you that instant surge forward. High-torque cars are especially practical when climbing hills or towing, never feeling sluggish; conversely, low torque makes acceleration feel weak. Diesel engines typically deliver higher torque, while gasoline engines run smoother, though turbocharging can significantly boost torque. This differs from horsepower, which relates to top speed—torque governs initial acceleration. In daily driving, torque levels directly impact both driving enjoyment and efficiency.
