Sensor based measurement and purge control of fuel vapors in internal combustion engines |
| 摘要 |
A fuel control system for a vehicle includes a pressure compensation module that compensates an intake oxygen signal based on an intake pressure signal and that generates a compensated intake oxygen signal. A blow-by estimation module generates an estimated blow-by flow. A purge flow estimation module estimates the purge flow based on the compensated intake oxygen signal and the estimated blow-by flow. A fuel control estimation module reduces fueling to injectors of an engine of the vehicle based on the purge flow. |

1. A fuel control system for a vehicle, comprising:
a pressure compensation module that compensates an intake oxygen signal based on an intake pressure signal and that generates a compensated intake oxygen signal; a blow-by estimation module that generates an estimated blow-by flow; a purge flow estimation module that estimates the purge flow based on the compensated intake oxygen signal and the estimated blow-by flow; and a fuel control estimation module that reduces fueling to injectors of an engine of the vehicle based on the purge flow. |
