Control of secondary air to an electrically heated catalyst using feedback control |
| abstract |
The injection of secondary air into the exhaust system of an internal combustion engine equipped with an electrically heated catalyst (EHC) upstream of a catalytic converter using a secondary pump is controlled by use of a dedicated heated oxygen sensor located downstream of the electrically heated catalyst in the exhaust stream from said EHC. The sensor measures the oxygen content in the EHC exhaust stream and sends a signal to a controller which turns on a secondary air pump when the signal from the heated sensor exceeds a pre-selected set point on the controller thereby injecting supplementary air into the exhaust stream from the internal combustion engine to the EHC. |
