The Functions of Motorcycle Carburetors

As far as we know, Motorcycle carburetor is a vehicle part where fuel is converted into vapor, and it is widely used in most gasoline vehicles. Nevertheless, with development and advancement of technology, a great deal of new vehicles do not have carburetors any more. Originally, carburetors were used in cars, however, they have been replaced by the electronic fuel injection technology recently. And now, they are widely used in smaller machinery, such as lawn mowers, chain saws, motorbikes, small boats, light aircraft, etc. Although the electronic fuel injection technology has various advantages like flexibility, reliability, and complexity, its higher cost makes carburetors a better choice for small engines.
For most laymen, the idea and construction of a carburetor may seen very complex, however, it actually is very simple. And regular check and maintain a motorcycle carburetor can ensure that the vehicle is performing in its peak condition. The basic principle upon which a carburetor functions is atmospheric pressure, which is the pressure that is exerted on anything and is around 15 pounds per square inch. A carburetor functions by varying the pressure between the engine and the carburetor.
In addition, there is a piston in a motorcycle that goes up (for a two-stoke engine) and goes down (on a four-stroke engine), and forms low pressure inside the crankcase causing the pressure outside to be higher. Because of this, air will continuously rush inside the carburetor until the pressure is equalized. This moving air picks up and gets mixed with vaporized fuel inside the carburetor that later burns due to the fire provided by the ignition, giving power to the vehicle.
Learning the basic principles of how a motorcycle carburetor functions can help one to keep it well tuned and functioning to its full capacity. A well maintained carburetor undoubtedly will burn fuel efficiently, and let out less exhaust and lead the vehicles to get better mileage.
You know, carburetors affect the performance of the engine as a whole. In addition to this, altitude, humidity, and air temperature will affect the engine performance as well. For example, a drop in temperatures means the cooler air will need more fuel to burn, while warm temperature ensures full performance of a motorcycle engine. Besides, with an increase in altitude, the air molecules decrease, causing the carburetor to require and consume more fuel. Humidity causes the same effect on the motorcycle carburetor and, as a result, on its end performance.
Since carburetor is an essential component in engine, which directly affect the engine performance, regularly checking and maintaining your motorcycle carburetor to keep it in its pristine condition is surely the first step to make sure that it runs well and is fuel efficient.
