Purge fuel flow rate determination method

A method of determining a purge fuel mass flow rate from a fuel vapor control system to an internal combustion engine having a compressor for delivering purge gas from the fuel vapor control system to the engine. The temperature rise of the purge gas passing through the compressor is determined. The...

Zusammenfassung:	A method of determining a purge fuel mass flow rate from a fuel vapor control system to an internal combustion engine having a compressor for delivering purge gas from the fuel vapor control system to the engine. The temperature rise of the purge gas passing through the compressor is determined. Then, a specific heat ratio of the purge gas is determined as the function of the temperature rise. The purge fuel mass flow rate is determined as a function of specific heat ratio of the purge gas.
