摘要： The ignition characteristics of a fuel are adjusted using a unit which has a distribution zone, a oxidation zone and a conversion zone. Fuel is distributed in the distribution zone having a distribution structure. A portion of the fuel is oxidised in the oxidation zone with a oxidising agent on a catalyst on a catalyst carrier, and a portion of the distributed fuel and/or of another supplied fuel is thermally and/or catalytically converted in the conversion zone. The ignition characteristics of the fuel are adjusted via: the molar ratio of oxygen included in the oxidising agent to the oxygen required for the complete oxidation of the fuel provided; and/or via the pressure in the unit; and/or the dwell time; and/or the temperature. Exhaust emissions, in particular NOx and soot emissions, can be lowered.

摘要： A control method for internal combustion engine includes forming an air-fuel mixture leaner than that at a stoichiometric air-fuel ratio in a cylinder by first fuel injection, performing second fuel injection to inject fuel toward the vicinity of a discharge channel of an ignition plug during a period in which the air-fuel mixture is undergoing a low temperature oxidation reaction in a compression stroke, and after the second fuel injection, performing spark ignition by the ignition plug at a timing at which a spark of the ignition plug reaches the fuel injected by the second fuel injection.

摘要： When a predetermined restart condition is satisfied after an engine is automatically stopped, whether or not a piston of a stopped-in-compression-stroke cylinder which is in a compression stroke falls within a specific range set at a bottom dead center side of a predetermined upper limit position is determined. When the piston of the stopped-in-compression-stroke cylinder falls within the specific range, a first compression start is executed in which fuel is injected from an injector into the stopped-in-compression-stroke cylinder for the first time and is then self-ignited. In the first compression start, a start timing of a first fuel injection operation with respect to the stopped-in-compression-stroke cylinder is set to be earlier as a stop position of the piston of the cylinder gets closer to the bottom dead center within the specific range.

摘要： The purpose of the present invention is to provide an engine with reforming cylinders which are fuel reforming devices capable of supplying a reformed fuel according to the outputs of outputting cylinders. The engine is provided with the outputting cylinders for burning the fuel and the reforming cylinders which are the fuel reforming devices for reforming the fuel through the reciprocating motions of pistons. The amount of reformed fuel supplied to all the outputting cylinders is changed according to the outputs of the outputting cylinders while maintaining the amount of supplied fuel and the amount of suctioned gas, which are supplied into one reforming cylinder.

摘要： An internal combustion engine is configured to operate in a homogeneous-charge compression-ignition combustion mode and a spark-ignition combustion mode employing late intake valve closing. A method for operating the internal combustion engine includes determining an amount of residual gas re-inducted into a combustion chamber from a previous engine cycle and determining an amount of fresh air trapped in the combustion chamber for the present engine cycle based upon the amount of residual gas re-inducted into the combustion chamber from the previous engine cycle. Engine fueling to the cylinder for the present engine cycle is controlled based upon the amount of fresh air trapped in the combustion chamber for the present engine cycle.
