Management of the maximum amount of air entering the engine

There is a lot of these reasons that the cylinders of the engine must not be a large amount of fuel injected (or the maximum number of physically possible):

- Excessive secretion of harmful substances in exhaust gases;
- Excessive secretion of soot;
- Mechanical overload due to excessive torque or limit the engine speed;
- Thermal overload caused by overheating of the cooling fluid, engine oil, or the turbocharger.

The maximum number of air entering the engine is formed from a large number of input variables, such as the mass of the incoming air, the engine speed and engine coolant temperature.
