Electrically heated catalyst control system and method |
摘要 |
An exhaust treatment system comprises M electrically heated substrates and a heater control module. The M electrically heated substrates are coated with a catalyst material and arranged in series to receive exhaust gas of an engine. M is an integer greater than one. The heater control module applies power to N of the M substrates to heat the N substrates during a predetermined period. N is an integer less than M. The engine is turned off and the M electrically heated substrates do not receive exhaust gas during the predetermined period. |
