Quick restart HCCI internal combustion engine |
摘要 |
The invention relates to an internal combustion engine operable in homogeneous charge compression ignition (HCCI) combustion mode and in conventional spark ignited combustion mode and a method for restart of HCCI combustion therein. Whilst cranking the exhaust valve is arranged to be closed before top dead center (TDC) during an exhaust stroke. The intake valve is arranged to be opened after TDC during an induction stroke. Fuel injection control means are arranged to perform a first fuel injection after closing of the exhaust valve and before TDC of the exhaust stroke. The ignition control means are arranged to cause said spark plug to ignite the first injected quantity of fuel before said opening of the intake valve. The fuel injection control means are arranged to perform at least one further fuel injection in the interval after TDC of the exhaust stroke and before TDC of a subsequent compression stroke.
