METHOD AND SYSTEM OF MANAGEMENT OF EGR (EXHAUST GAS RECIRCULATION) FOR INCREASED ROAD QUALITIES

摘要

1. A method for an engine, comprising: blowing an EGR system when the oxygen content of the EGR is lower than the threshold oxygen content, the oxygen content of the EGR is determined in response to closing the EGR valve. 2. The method according to claim 1, wherein the purge of the EGR system is to open the EGR valve to a smaller than threshold opening of the valve. The method of claim 2, wherein the purge of the EGR system further comprises opening the EGR valve less than the first threshold time. The method of claim 3, wherein purging the EGR system further comprises closing the EGR valve when the inlet oxygen level is greater than the upper threshold oxygen level. The method of claim 1, wherein the purge of the EGR system is stopped when the EGR content is greater than the threshold oxygen content. The method according to claim 1, wherein closing the EGR valve comprises closing the EGR valve for longer than the first threshold time. The method of claim 1, wherein the purge of the EGR system is to open the EGR valve only when the oxygen level at the inlet is greater than the threshold oxygen level at the inlet. A method for a vehicle engine, comprising: blowing an EGR system, including, opening an EGR valve when the EGR valve would otherwise be closed, based on a measured oxygen concentration of the EGR system that is lower than a threshold oxygen concentration. The method of claim 8, wherein the measured oxygen concentration is measured after closing the EGR valve. The method of claim 8, wherein opening the EGR valve is opening an EGR valve with a threshold opening of the valve, and then closing the EGR valve after a threshold time. The method of claim 10, wherein opening the EGR valve is
