To make the performance of the engine, the piston must always move up and down, insert a combination of fuel and weather, mengompresikannya, thank and encourage gas explosion in the combustion former life. In each step of the named cycles.
4 stroke engine requires four times the piston moves from TMB - TMA (2 turns the crankshaft) is 2-step machine only requires half of the ability of the machine 4 steps.
2. STEP
Momentum piston bertranslasi of TMB - TMA, single-piston motion named step, or simply that the distance between the point of stopping the piston in the cylinder is measured in units of millimeters (mm)
3. POINT OFF (TMA) OFF POINT DOWN (TMB)
Namely the stopping point of the piston, the upper limit or lower limit, TMA is point at which the piston starts moving downwards, thus the opposite of the point TMB piston starts moving upwards.
Harga Motor 4. BORE
Meaning to mention the amount of the diameter of the cylinder bore harga motor .
5. CRANK ANGLE
Degree crankshaft made by the axis line of the crank and a line drawn from the pen to the center of the crank with the coefficient on TMA - TMB.
6. Displacement
When the piston moves from the top (TMA) goes down (TMB) there is content that is inhaled by the piston, piston displacement, is also a step volume can be calculated via the formula:
V
V = volume
= Constant 3, 1416
r = half the diameter of the bore
L = length of stroke (step)
N = Number of cylinders
7. VOLUME FUEL ROOM
Fill the room on the cylinder head and piston when the piston is at TDC.
8. VOLUME CYLINDER
Ie the sum of the piston displacement volume of the room added fuel.
9. COMPARISON OF COMPRESSION
Values ​​shown from the results of the division of the volume of a cylinder with a fuel volume of the room. Expressed by the formula
RK = Volume Cylinders / Fuel Volume rooms
High compression  ratio engines intended for use in high performance and speed, but there are some specific restrictions on the compression ratio.
10. SPEED PISTON
Piston movement of TMA-TMB must have speed, fitting dititik TMA - TMB piston speed is 0 and tervepat in the middle step. Therefore, the piston speed shown by the average speed.
Speed ​​= LN / 30
L = Length of step
N = Round Machine (RPM)
11. CHARACTER MACHINES
In the composition of the same displacement engine, each engine has different characteristics, depending on the magnitude of the diameter of the piston and step length.
- Machine OverBore .... Step smaller than the diameter of the piston.
- Machine Square ... Steps and the same piston diameter.
- Machine OverStroke ... Step greater than the diameter of the piston motor terbaru.
Compared with long strides and square engine, engine over-bore easier to make the engine speed and the power generated can be even greater. When the average engine speed, the speed of the piston can be made lower frictional constraints also can be reduced. More compact machine design, machine design racing machines are often superior. Therefore, modification BORE UP, or so large diameter piston easier making the speed and power compared STROKE UP
