General
The air mass, along with the coolant temperature, engine speed or fuel temperature, is one of the most important factors required by the engine management to regulate the injection quantity. The injection quantity can only be exactly calculated with the aid of the air mass.
Function
Determination of the air mass occurs over the engine management (MR) control unit. It detects the air temperature and air pressure in the charge-air distributor via the charge air pressure and temperature sensor and uses these to calculate the air mass.
Acquisition of the air temperature in the charge-air distributor takes place over a temperature sensor that is located at the tip of the charge air pressure and temperature sensor.
Acquisition of the air pressure in the charge-air distributor takes place over a pressure sensor that is located in the inside of the housing of the charge air pressure and temperature sensor.
