Exhaust gas recirculation transient smoke control |
摘要 |
A method for controlling an internal combustion engine having an EGR circuit including an exhaust gas recirculation valve for diverting exhaust gas from an engine exhaust to an engine intake includes ascertaining a predefined threshold based on at least one engine operating condition and preventing the EGR valve from opening if the at least one engine operating condition is below the predefined threshold to reduce or eliminate visible black smoke which may occur during transient conditions. In one embodiment, the engine operating condition represents EGR boost pressure.
