Reducing undesirable components of automotive exhaust gas
Patent
·
OSTI ID:7353503
Undesirable pollutants in automotive exhaust gas are reduced using an emission control reactor to oxidize hydrocarbons and CO, and recirculation of some exhaust gas to the engine intake system to reduce NO/sub x/ content. The warm-up time of the reactor is reduced by delaying the ignition time until the minimum working temperature of the reactor is attained. The performance of the engine is improved by interrupting exhaust gas recycle when the engine is choked, or at idling or operating with open throttle.
