TORQUE AND POWER

Torque Components

Torque is the force press play on the rotating part. Motorcycle driven by a torque generated crutch. Torque can be calculated through the formula

T = Force x Distance

If the force F (kg) employed to rotate the object along the R (m), to tighten the bolt mass, then the torque used is FR (Kg m), as changes in torque from the primary reduction between the crankshaft primary gear with the clutch teeth secondary house, channeled to primary teeth on the gear transmission of secondary transmission, then connected to the primary tooth final gear forwarded through the chain on the final secondary gear teeth to be able memutra rear wheels.If a torque F works on gears A with radius r, associated with the gears B with radius 2r, the torque on gears B despite the greater the rotational speed is reduced into half.

In the machine!

The length of the piston step is twice the distance of the center of the crankshaft to the big end (crank pin), explosion produces compressive force the piston to push the piston down until then rotate the crankshaft. Therefore the engine torque will change according to the magnitude of the force generated (F) for a fixed distance. The size of the force F is changed according to engine speed, this means influenced by the efficiency of combustion, it helped change the amount of torque.

Digital Torque Meter

In fact the performance of any engine has a saturation point, at a specific velocity, peak torque (maximum torque). But kenanikan next engine speed will not increase the torque.When the motor operates at maximum torque round the rear wheel force also the maximum spin. How to increase the torque, there are two ways: increase the resulting explosion pushing the piston engine to be able to more quickly, or extend the pistons move.

Power

Average performance is measured by time. Crankshaft torque drive a motorcycle, but this is only the force to drive the speed of the motorcycle was not taken into account. Power is work which can lead to speed.

Power = Work / Time. Kg, m / sec

Unit of power expressed in PS (Pferd Starke-GERMANY) or 75 kg.m / sec, meaning that these workers were able to move objeck weighing 75 kg with a mass of 1 meter in one second, the greater the engine's ability to move objects in a unit time, it means the the greater the power output. The more the total weight of the vehicle and rider, it also requires more power to achieve the same speed.

Generating a large torquePower at crankshaft can be measured with the formula,

Q = 0.0014 NT

 
Where N, is the engine rpm, and T is Torque. Engine power output will vary depending on the torque generated by the engine speed, the higher the engine speed, the greater the power. Therefore at a certain speed, the torque starts to decrease.When the energy reaches maximum, this is called "Maximum Power" and at some point will reach the peak point of exhaustion until engine speed is no longer able to raise power.
