COORDINATION OF CAM TIMING AND BLOW-THROUGH AIR DELIVERY |
| 摘要 |
Methods and systems are provided for reducing turbo lag by directing intake air from an intake manifold to an exhaust manifold. The intake air may be directed via an EGR passage by opening an EGR valve or by may be directed via engine cylinders by increasing positive valve overlap. Amounts of air directed via external EGR and air directed via positive valve overlap are based on engine operating conditions. |

1. A method for an engine, comprising:
directing intake air from an intake manifold, downstream of a compressor, to an exhaust manifold, upstream of a turbine via each of external EGR and positive valve overlap through a cylinder, wherein amounts of air directed via EGR and air directed via positive valve overlap are adjusted based on conditions. |
