Process to determine the intake pressure of an IC engine in a car consists on monitoring the mass flow rate through the valve, calculating the pressure difference on the filter from these data and determining the pressure before the valve

摘要

Pressure determination process consists on monitoring the mass flow rate (m1) through the valve, calculating the pressure difference (pab) on the filter from these data and determining the pressure before the valve. The final step consists on determining the ambient pressure (pumds) and the engine working quantities. Independent claims are also included for a memory for the command of the IC engine, an IC engine and a command apparatus for the IC engine.
