Relation between Torque and Horsepower on car

Relationship between torque & Horsepower on the vehicle

Torque 

Torque is a rotating force produced by an engine's crankshaft. The more torque an engine produces the greater its ability to perform work. Torque can be viewed as the strength (capability) of the vehicle. 

Newton-meters measures of torque How much torque is generated?

Torque =Froce x Distance  

" Torque- the amount of force"

The engine produces maximum torque at the lower to middle end of the engine speed, i.c approx rpm 1500 onward.

Torque is the output value of the engine as well as the revolution per minute (rpm).

Torque x rpm / 5252

Diesel Engines features more torque at a lower rpm gasoline engine, which results in better capability (strength) for work as hard to get the vehicle moving. Torque provides a simple measurement of the maximum twisting force that the engine can generate when working hard and load. This is why pick up truck high torque engine that generates more torque than a small car. Engine torque is multiplied by gears lower the gear selected i.e first gear which has a high gear ratio, greater is the pulling ability of the engine.

Example -  You apply torque to the top of a screw-top jar when you loosen it. You apply torque to the steering wheel when you steer the car around a curve.

 The engine applies torque to the car wheel So they rotate.

Horsepower

The power produced by an engine is called horsepower. In other words, power the rate of completing work (or applying torque) in a given amount of time. Power measures how often a force is applied over a certain period.

Horsepower = amount of force, 

                                   rate of the force application.

Mathematically,  multiplied by rpm.

HP = Torque X RPM / 5252

In the content of I C Engine

Horsepower equal Horsepower translates into speed so, if you want to go faster get torque up to speed quicker, you need more horsepower. Horsepower provides the measurement of the engine overall performance and conveys the engine overall capability across all condition On the other hand maximum power is developed when the engine run at its maximum speed. 

Relates with torque & horsepower 

Horsepower and torture are the primary measurements of drivetrain power. Both are the twin output of an engine. They are related and proportional to each other by speed. In both cases a certain amount of force is present but what's different in the direction of that force. Torque and horsepower have different characteristics, often peaking at different engine speed ranges, better as revolution per minute (rpm).

Let's take an example:

* Mahindra Bolero Pick up truck 2523 CC/ 2.5 litres (four-cylinder engine).

Power of 70 bhp @3200 rpm torque of 200Nm @1400-2200 rpm.

* Toyota Innova MUV segment car has 

2495 CC/ 2.5 litres (four-cylinder engine).

Power 130 bhp @ 5600 rpm max. Torque 181Nm @ 4000 rpm.

* Force Traveller minibus/Van has

  2.6 litres (four-cylinder engine).

Power 90 bhp@ 2800 rpm Torque 250 Nm @ 1400-2400 rpm.

Between them, the differences are their torque and horsepower.

 Bolero pick-up truck more capable of strength able manages to take a load driven its moderate speed. its means, that it has more torque.

Whereas Toyota Innova car more speed of both of them as compared to horsepower.

So, Force Motor Traveller minibus/van has more torque, which means that manages to able to carry loads and weight and riding quality between them 

especially in steep or incline road conditions.
