METHOD AND APPARATUS TO CONTROL TRANSITION BETWEEN HCCI AND SI COMBUSTION IN A DIRECT-INJECTION GASOLINE ENGINE |
| 摘要 |
<p>A method for transitioning operation of a spark-ignition, direct- injection internal combustion engine having a two-step, variable phase valvetrain between HCCI and SI modes includes providing a low-lift intake valve, un-throttled stoichiometric SI operation intermediate a low-lift exhaust and intake valve HCCI mode and a high-lift exhaust and intake valve, un- throttled SI mode.</p> |
