Horsepower is measured at higher RPM’s and torque is the low-end “grunt” or low RPM pulling power of an engine.
Diesel engines only make around 300-400HP in those big rigs, but they make anywhere from 1,500 – 2,000 Ft.
Lbs of torque, which is what pulls the 80,000 Lbs of payload in a fully loaded big rig.
What is the meaning of engine torque?
Torque, in simple terms, is ‘Twisting or Turning Force’. It is the tendency of a force to rotate an object about an axis. In automotive terms, it is the measure of rotational effort applied on engine crankshaft by the piston. The amount of torque that an engine can exert depends upon the engine RPM.
Why is torque important in a car?
This is why, usually, specs on vehicles gives the (peak ) torque at the crankshaft and gives also the RPM at which the engine attains it: 200nm@3000rpm. A simple example to understand torque is to make a comparison to a farmer hoeing a field. The RPM of the engine is how many hoe blows the farmer can make in a minute.
Does more torque mean faster acceleration?
More horsepower generally means a car has a higher top speed, while more torque generally means a car can accelerate faster.
