How Does an ATV Carburetor Work?
All-terrain vehicles, also known as ATVs, operate with internal combustion engines. Internal combustion engines are powered by a reaction caused by the burning of a combination of fuel and air. A carefully measured mixture of air and fuel is trapped in a combustion chamber called a cylinder. The cylinder, connected in a line with several other cylinders to form what is called an engine block, has a piston at one end. The trapped mixture of air and fuel is ignited using a spark plug, and the resulting explosion pushes the piston out of the cylinder. The movement of the piston produces energy for the engine. The mix of fuel and air that is ignited in the cylinder must be in the correct proportions or the engine will not fire properly. The device that regulates the flow of both air and fuel into the cylinders is called a carburetor. The movement of the piston down into the cylinder draws air through the carburetor, which causes the pressure in the carburetor to drop. The lowered pressure
