System for air-fuel ratio control |
摘要 |
A system and a method of controlling an engine during and after a temporary fueling shut-off during idling, deceleration or a switch to auxiliary power generating device is presented. According to this method, maintaining power to the heater of an exhaust gas sensor during the temporary shut-off, and thus keeping the sensor operational shortly following resumption of fueling can eliminate a delay in closed loop air-fuel ratio control. This method provides improvements to fuel economy and emission control.
