Effects are Short Stroke Engine

As we have seen on the motorcycle handlebar piston output is now shorter than the output of the motorcycle before the year 2000 Many of the changes made ​​by the motorcycle industry by reducing the length of the motor seker step, in order to achieve better engine performance. Coupled with the demands of the motorcycle market is currently demanding fuel savings, in order to cope with the global energy crisis.
Trimming the piston stroke motorcycle engine aims to speed up to reach high rpm. With the reduced length of the piston stroke, the piston step be cut also, or shorter. The pistons move from TDC towards BDC becomes shorter. So the up and down movement of the piston becomes shorter, which will also affect the rotation of the crankshaft kecapatan or we call the engine rpm.
Another advantage gained is fuel thrifty. With the shortening of the step piston / piston, so long sucking fuel into the suction step or a brief moment. And result in a reduction in the amount of fuel sucked.
Still, this piston-cutting measures have shortcomings.
Do you remember the principle of the lever on the physics lesson. If we want to alleviate the power to leverage an object, then the stalk lever made ​​longer. And vice versa, if the lever is getting shorter, the energy required greater leverage. Because of the work of the lever will be heavier.
So what to do with cutting the handlebar piston?
With long terpotongnya handlebar piston, just the same as making a short stalk lever. And this makes the weight force of combustion in the combustion chamber. By the time the average and standard load transported, then it is not visible. However, at the time of the ramp, the power generated by the long handlebar piston will be greater. Or simply when the uphill road motorcycles and cars berstang will quickly drove the length of the piston when compared to the handlebar sehernya tanjakkan short.
But while the average fixed berstang short piston drove faster than the piston berstang long.
