2013 MOTORCYCLE MOVEMENT STEP PISTON

Movement Step Piston

Final discussion on the piston .. the following discussion, we will discuss about the valve. let's see
To ensure that the engine operates, the piston must always continuously moving, the movement of the piston will stop at TDC (Top Dead Point) or TMB (Bottom Dead Point). Both of these points called dead center. When the piston moves upward, from BDC to TDC, or moves down from TDC to BDC, one single motion of the piston called "step", a distance of movement of the piston is measured mm.
To produce more power, do research the relationship between stride length with a diameter of piston. The composition of stride length and diameter of the piston shown by Figure 1. Short step machine can make the escape velocity higher, and allows for higher power as well.

Step movement of the piston in the cylinder chamber is a movement straight or linear. To utilize the linear movement, the movement should be converted into a rotary motion (rotary). Change is carried out by the movement of the crankshaft. In the four-stroke cycle engine, the cycle consists of four time step piston, two up and two down. This cycle occurs during two crankshaft rotations. While the two-cycle engine, one cycle of the piston there are two steps, one up and one down. This cycle occurs during one rotation of the crankshaft.
