ENGINE CC?? CONCEPT, USE , CALCULATION , USES etc. ALL EXPLAINED

What is engine CC??Friends ..... We all ask about CC when it comes about bike.Do u know why does that CC stands for ?? Why more CC means more power??Why bigger CC consumes more fuel?? Why CC is the most important part of a engine?? And how to measure it??

CC stands for cubic centimeter . As its name, it  describes the the internal size of an engine.



A measure of the displacement of the engine is volume , this volume is known as CC (cubic centimeter). This the sum of volume of all individual engine .

Normally,
           CC =  no. of cylinder  ❌  volume of all individual engine
       ⇒CC= no. of cylinder❌   cross section area ❌ stroke length.

Ex- 
      If a bike has 200CC,  that means it has displacement equivalent to 0.2 litter. 
     or  If a four-wheeler have 1500CC, that means it has a displacement equivalent to 1.5L .

USES

cc's are generally used for small model engines (just a few cc's). 

motorcycles (10's of CCs to 1000 or more) ,

small cars (up to about 2000 cc). 

Litters are used for larger cars. E.g. 1.4, 1.8, 2.0.2.4, 2.8 3.0 litters are common measurements, they go up to big V8s which can be 6 litters or more.

CC & POWER

Yes , a larger displacement eats more fuel & air mixture. Because to develop more power it sucks more air-fuel mixture. Thus it develops more power. So a bigger CC means more power & all other things being equal and optimal.A bigger CC means less millage , more power & more maintenance .


But those are not always same.A large displacement engine may can produce a lot less power than a smaller CC engine and this is be done by changing compression ratios, larger or smaller fuel and air injection, different exhaust ports, and turbo chargers. Large displacement engines are naturally heavier when made the same way so high performance cars will try and get more power from a smaller engine with more costly features.


So during buying a bike, don't forget your needs. For a normal rider 100-125 cc will be OK. For racer more cc is necessary.
