Carburetor:
A device used on gasoline powered engines, in which the gasoline from a fuel pump connected to a fuel tank or fuel cell is mixed with filtered oxygen from the engine bay (or if it has a cold air intake then the oxygen is from outside the engine bay), which this mixture is one of the keys in internal combustion. This combustion is possible with the heat of a spark plug, which has at least 1 per cylinder, and the pistons compression is a key to compressing the fuel-air mixture towards the spark plug to ignite an explosion. With these mini explosions, it is possible for any engine to gain RPM, produce torque, and thus make your car move in a given direction. Most common example of carbureted engines is in most lawnmowers and on ALL cars made before the 1980s (there were cars with carburetors in the early 2000s, i.e. the reliant robin mk3). In a nutshell, a carburetor is simply how the fuel and air make it inside the engine of your grandpa's old farm truck. Diesel engines do not and never had used carburetors in the history of an internal combustion engine
