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.

摘要： The present invention relates to an internal combustion engine for motor vehicles. The engine can be operated in homogeneous charge compression ignition (HCCI) combustion mode and in conventional spark ignited (SI) combustion mode. For increasing volumetric efficiency and charge temperature during homogeneous charge compression ignition combustion operation timing, duration and lift of the intake valve and the exhaust valve respectively, being controlled such that an amount of residual exhaust gases is trapped in the cylinder of the engine. An intake valve is opened at a timed moment after top dead center during an induction stroke of the piston such that a pressure wave is generated from an intake manifold into the cylinder. The intake valve is closed at a timed moment before the pressure wave is reflected within the cylinder such that a charge mass of said pressure wave is retained within the cylinder.
