Fuel system

The fuel system is an important component of gasoline engines that is responsible for mixing gasoline—the fuel of the engine—with air in an appropriate ratio and then supplying that air-fuel mixture to the cylinders.
Gasoline, which is stored in the fuel tank, is sent from the fuel tank outlet to the carburetor after passing through the fuel filter, which removes any contaminants such as dirt.
The carburetor then ejects the gasoline in an atomized form that mixes with air to create an air-fuel mixture that then passes through the intake pipes before being taken into the cylinders.
The fuel system is also an important component of diesel engines in that it is responsible for injecting high-pressure fuel in an atomized form into the high-temperature, high-pressure air being drawn in and compressed by the engine pistons.
Fuel is first sent from the fuel tank to the fuel filter to remove any contaminants such as dirt, dust, or moisture.
The fuel then enters the fuel injection pump (injection pump), where it is subjected to high pressure before being passed through the injection pipe, after which it is forcefully injected from the fuel injector (injection nozzle) into the combustion chamber.
The fuel injector also has a return pipe that is used to return any excess fuel to the fuel tank.
