METHOD AND SYSTEM FOR ENGINE CONTROL |
| 摘要 |
Methods and systems are provided for adjusting a transmission shift schedule in engine systems configured to operate with multiple fuels. During low engine speed and high engine load conditions, when an air charge temperature is elevated, engine operation is shifted from gasoline usage to CNG usage. The torque advantage of CNG usage is leveraged to advance a transmission upshift schedule and delay a downshift schedule to improve vehicle responsiveness when operating with CNG only. |
