摘要： A control device for an internal combustion engine is configured to feed fuel to a combustion chamber in an intake stroke to form a homogeneous premix and make the homogeneous premix burn by flame propagation when a temperature of an engine body is less than a first threshold value, to feed fuel to the combustion chamber in the intake stroke to form a homogeneous premix and make the homogeneous premix burn by compression ignition when the temperature of the engine body is the first threshold value to less than a second threshold value larger than the first threshold value, and to directly feed fuel to the combustion chamber in a compression stroke to form a partial premix and make the partial premix burn by compression ignition when the temperature of the engine body is the second threshold value or more.

摘要： Emissions of polynuclear aromatic hydrocarbons (PAHs) from diesel engines may be reduced by blending a renewable hydrocarbon distillate with a base diesel fuel. The base diesel may be a fossil diesel fuel, a Fischer-Tropsch diesel fuel as well as a hydroprocessed biodiesel fuel or a combination thereof. The renewable hydrocarbon distillate is a fraction from hydrotreated bio-oil having a boiling point between from about 320° F. to about 700° F.

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： 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.

摘要： Provided are a controller and a control method for a homogeneous charge compression ignition engine, which are capable of obtaining a highly efficient and stable combustion state over a wide range of load condition. A correction factor computing section executes combustion control with an excess air ratio smaller than approximately 3 when a predetermined condition is satisfied and computes a correction factor for correcting deviations between execution values of valve-opening timings and valve-opening periods of an intake valve and an exhaust valve and basic valve-opening timings and basic valve-opening periods of the intake valve and the exhaust valve which are previously determined for each operation condition, based on a timing at which an ion current becomes maximum detected by a combustion-timing detection section, in the combustion control with the excess air ratio smaller than approximately 3.
