This is also known as the "displacement" of a motorcycle.
The "CC" is one of the most basic things you have to understand about a motorcycle engine.
This is also an important factor in the engine of a motorcycle, as it has a direct impact on the power output of an engine and also the fuel efficiency.
Here I explain everything you need to know and understand about the Displacement of a Motorcycle:
If you've ever heard someone say that the best thing to do for a beginner is to ride a small motorcycle, smaller than 200 or 250 cc. But, you don't really know what they mean, this can help you clarify your doubts.
What do the cc or cubic centimeters of a motorcycle mean?
Well, the "CC" is a measurement of the volume of the cylinders of an engine that, in the most basic way, can help you to know the power of a motorcycle. Now, be very clear that there are also other ways that determine the power of the motorcycle, but this can help you start to get an idea on the subject.
I would like to tell you first a basic explanation of what the CC of a motorcycle means:
CC comes from the acronym (Cubic Centimeters) and refers to the displacement or capacity of an engine.
It is the space that exists inside the engine cylinder.
When we talk about a motorcycle engine, generally, people are referring to three basic things:
- CC (cubic centimeters)
- Number of cylinders (1,2,4 ... etc)
- Position of the cylinders in the engine, for example, it can be a "V" engine or in-line engine, there are different configurations, but that is a separate issue.
How to calculate the displacement of the motorcycle? (and what you should understand).
This is calculated from taking three elements:
Cylinder diameter,
The stroke of the piston, that is, the distance that the piston travels (Top dead center to bottom dead center)
Number of cylinders.
Note: Displacement is also known as "engine displacement" which is the path that the pistons travel within the cylinder.
Engine operation:
To understand the displacement of an engine you must first know the operation of an engine, basically ...
The pistons within the engine cylinder move in a reciprocating motion, that is, up and down, and this in turn rotates the crankshaft to convert its motion from reciprocating to rotary.
The volume within a cylinder changes as the piston moves through the combustion cycle and simultaneously, the other cylinders change in volume as their pistons move through other phases of the combustion cycle.
So while the volume of the individual cylinders changes as they move, the overall volume of the engine remains constant.
The Formula to know the CC (Cubic Centimeter) of a MOTORCYCLE:
Let us remember that as this is a science, it is necessary to delve into mathematics and physics a little to know how to calculate the displacement of a motorcycle engine:
The equation or formula necessary to calculate the displacement or displacement of an engine is:
Engine displacement (CC) = PI / 4 * diameter² (of cylinder) * stroke * number of cylinders.
And now, putting the math aside …
Why is engine displacement important?
Well, the displacement or displacement of the engine is a determining factor in the power and torque that an engine produces, as well as in the amount of fuel that engine consumes.
Generally speaking, the higher the displacement of an engine, the more power it can generate, and the smaller the displacement, the less fuel it can consume.
That is, engine displacement has a direct impact on the amount of fuel that must be put into the cylinder to generate power and keep the engine running.
A high-displacement engine absorbs more air/fuel mixture per revolution; therefore, more fuel is consumed.
Important: Remember that there are also other factors that influence the power or efficiency of an engine, such as The fuel supply, the ignition systems, the valve train design and forced induction, but, well, for that you understand this in a simpler and more basic way:
"A bigger engine is more powerful and a smaller engine is more efficient."
An example to calculate the air/gasoline mixture that fits in a cylinder, let's say:
A single-cylinder will fit 150cc of mix, if that engine has two cylinders, then you will have a 300cc motorcycle and so on.
I hope it was not a very complicated explanation and now you are clear about what this CC or engine displacement is.
