Will a car with more torque beat a car with more horsepower?

Will a car with more torque beat a car with more horsepower?

Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.

What is the relation between BHP and torque?

In fact, brake horsepower is derived from a calculation that relies on torque: BHP = Torque X RPM / 5252. Defined simply, multiply the torque by the axis’s rotational speed per minute (RPM) and you’ll get the engine’s final power output.

How does the engine power and torque vary with the engine speed?

The engine torque reaches its peak value at a speed where it is most efficient. In other words, the engine efficiency is at the maximum at a speed where it produces its peak-torque. If you raise the engine above this speed, its torque starts to decrease because of the increased friction of the engine’s moving parts.

What happens to the engine torque as the speed of the engine increases?

Maximum torque is obtained at a certain rotational speed, and maximum power at a higher rotational speed. An engine is flexible if these maximums occur at widely different rotational speeds, say in the ratio 1:2 or more. Conversely, if the speed increases then the torque increases and the speed increases even more.

How is speed related to torque?

Torque is inversely proportional to speed. Thus, when speed increases, torque will decrease.

How is engine power and torque calculated?

Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.

How do you torque an engine?

The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the RPMs. The problem with torque, however, is that it is measured in two different places: directly from the engine and to the drive wheels.

What is the relationship between torque and speed?

Since the rated output power of a motor is a fixed value, speed and torque are inversely related. As output speed increases, the available output torque decreases proportionately. As the output torque increases, the output speed decreases proportionately.

How do you calculate bhp from torque?

engine 1 : bhp = torque * rpm / 5252 = 147.49 * 2500 / 5252 = 70.20 bhp. engine 2 : bhp = torque * rpm / 5252 = 73.74 * 5000 / 5252 = 70.20 bhp. As you can see, engine 2 which is just 1 ltr produces the same amount of power as that of the bigger 2 ltr’d engine, inspite of having half the torque.

What is brake horse power (BHP)?

The Brake Horse Power is the unit of power of an engine without any losses like heat and noise. The BHP determines the acceleration and top speed of a vehicle. Often fast and quick vehicles will focus more on the BHP than the torque.

How do you calculate power at the RPM where peak torque?

But see what happens when we calculate the power at the rpm where peak torque is produced. engine 1 : bhp = torque * rpm / 5252 = 147.49 * 2500 / 5252 = 70.20 bhp. engine 2 : bhp = torque * rpm / 5252 = 73.74 * 5000 / 5252 = 70.20 bhp.

How do you calculate horsepower at low rpm?

Horsepower (HP) is calculated by multiplying torque by RPMs. Therefore, engines with a lot of torque can also produce a lot of horsepower at low RPMs. A low-torque vehicle can still produce a lot of HP, but it will take the vehicle longer to get there because you have to rev the engine more to build up HP and get to the peak level.
