    摘要： A direct fuel injection engine is provided that an appropriate stratified fuel-air mixture is formed to conduct good stratified combustion over a wide range of loads. The engine has a fuel injection valve that is arranged at an upper surface of the combustion chamber on or near the center reciprocation axis of the piston and oriented such that the injection center axis of the fuel stream injected therefrom is slanted with respect to the center reciprocation axis of the piston. The piston is disposed in the combustion chamber to move along a cylinder center axis. The piston has a top surface having a first outer cavity having a first cavity center axis, and a second inner cavity located in the outer cavity. The second inner cavity has a second cavity center axis offset from the cylinder center axis of the piston in a direction perpendicular to the cylinder center axis.

    摘要： In an exhaust path, a HC trapping material which traps HC contained in exhaust gas temporarily, a H2O trap which traps H2O contained in exhaust gas and a CO oxidation catalyst are arranged in this order from the upstream side, wherein the H2O trap is disposed just upstream of and close to the CO oxidation catalyst. H2O and HC which are components disturbing the activity of the CO oxidation catalyst can be removed efficiently and the adsorption heat and condensation heat of H2O can be efficiently utilized to raise the temperature of the CO oxidation catalyst so that early activation of the CO oxidation catalyst is accomplished just after an engine starts.

    摘要： An upstream catalyst (12) which stores oxygen in exhaust gas and releases the stored oxygen for oxidizing a reducing agent component contained in the exhaust gas, and a downstream catalyst (13) which stores nitrogen oxides in the exhaust gas and releases the stored nitrogen oxides by reducing the stored nitrogen oxides by the reducing agent component contained in the exhaust gas, are provided in an exhaust passage (11) of an engine (2). When the storage amount of nitrogen oxides of the downstream catalyst (13) reaches a predetermined value, additional fuel is injected from a fuel injector (7) after combustion, and stored oxygen in the upstream catalyst (12) is released by the reducing agent components in the additional fuel. After release of oxygen, the supply of the additional fuel is stopped and the supply of the main fuel is increased.

    摘要： An internal combustion engine (101, 601, 901) alters an effective compression ratio from an effective compression ratio for a start-up operation to a larger effective compression ratio for a normal operation when an engine rotation speed (NE) increases beyond a resonance rotation speed region during cranking. A controller (104, 610, 910) determines whether or not the engine (101, 601, 901) has reached a combustion possible state on the basis of the engine rotation speed (NE) during cranking and an operating parameter (PA, TA, TW, P_Rail, V_Ang) other than the engine rotation speed (NE) (S1102, S1202, S1204). When the determination is negative, the controller (104, 610, 910) inhibits fuel supply to the engine (101, 601, 901) by a fuel supply device (207), even when the engine rotation speed has increased beyond the resonance rotation speed region (S406). In so doing, a combustion defect such as a misfire is prevented.
