Mass airflow sensor for pulsating oscillating flow systems |
摘要 |
A method for calibrating an output signal of a mass airflow (MAF) sensor in operative communication with an induction system of an internal combustion engine is provided. The method comprises the steps of determining an engine speed value, determining a maximum MAF output signal value at the engine speed value, detecting a mean MAF output signal value at the engine speed value, and correlating the MAF output signal with an airflow rate value as a function of the MAF output signal value, mean MAF output signal value and engine speed. The present invention is particularly suited to improving the MAF sensor output of internal combustion piston engines having pulsating airflow including gaseous-fueled engines.
