What is altitude mixture control?

Gives a pilot control of the amount of fuel the carburetor or fuel injectors deliver to the air intake for a piston engine. The fuel and air, now a "mixture", are combusted in the cylinders. As altitude changes, air pressure changes. The pilot can optimize the fuel at different altitudes for the best engine power or for the least amount of fuel burn.

What is the purpose of carburetor?

The main purpose of the carburetor is to control the mixture of fuel vapor and air that goes into the engine. The carburetor changes this ratio depending on the car's situation. It puts in a small amount of a very rich fuel mixture when the engine is cold and running at idle. With the throttle plate closed and air limited because of the closed choke plate, engine suction is amplified. More fuel is provided when the gas pedal is depressed for acceleration.

What is the carburetor?

It's a device that mixes fuel and air prior to the engine pulling the mixture into the cylinders for combustion. The carburetor also allows the vehicle operator to control the power/speed of the engine by controlling the amount of air that is allowed into the engine.


How does carburetor works?

A carburetor mixes air and fuel in appropriate proportions. Air and Liquid fuel are the inputs to the carburetor at different points of the carburetor. Due to suction created by the working engine , atmosperic Air is accelerated through the venturi in the carburetor. Accelerating Air sucks Fuel into the venturi at its center from a level regulated liquid fuel pot in the carburetor,due to the venturi action. (Bernoulli's Principle) During the process of sucking the fuel is atomised /becomes a mist , as it enters the venturi. The atomised fuel then evaporates and mixes with the air uniformly. This uniform gaseous mixture of fuel and air is the out put of the carburetor. This gaseous mixture then enters into engine cylinders for combustion.
