Many people think that the engine is running on gasoline. But this is not true. The engine runs on a mixture of gasoline and air. That is, the fuel-air mixture. On one gas, he can not work, so it requires dilution of gasoline with air.

Ideally, the ratio of gasoline to air in the mixture is 1 to 14.7.
that is one part of gasoline, you have 14.7 parts of air. Such a mixture is called stoichiometric, that is, it air for as long as necessary for complete combustion of the fuel.
A 14.7 to one this ratio is denoted as Lambda.Osyuda and the name of the oxygen sensor.

However, as you know, ideal conditions do not exist, therefore, in the injection control, there are sensors that are designed to adjust these parameters and match them to the ideal.

In other words, when the motor control unit constantly adjusts the fuel delivery based on several parameters.

The main parameter that determines the amount of fuel injected into the cylinders, is the mass of air sucked into a cylinder per working cycle.
