Management and tuning

Manufacturers apply techniques to extract more power and efficiency from an engine. Adding more air to the combustion chamber (filling pressure) increases the degree of filling. The correct amount of fuel can be adjusted to the filling level using software. This results in more energy, and therefore more torque. The moment we increase the fill rate and the fuel injection, we are in the process of tuning. The techniques that play a part in this optimization are shown in this overview.

With an incorrect amount of fuel in relation to the amount of air, we speak of a mixture that is too lean or too rich. Fuel trims are a correction factor to the base amount of fuel injected. Fuel trims are formed and used by the engine management system.
