摘要： PROBLEM TO BE SOLVED: To reduce shock by correctly controlling the idle rotation number in N to D selection after starting. SOLUTION: Target idle rotation number NsetN in N-range after starting is set high for early activation of catalyst. As N to D selection is detected, the target idle rotation number is reduced for a prescribed period (200ms) to first target idle rotation number Nset1 for D-range. After pass of the prescribed period, the target idle rotation number is further reduced to second target idle rotation number Nset2 for D-range. While the target idle rotation number is set at the first target idle rotation number Nset1, delay quantity RET for ignition timing is set in accordance with actual engine rotation number Ne. The higher the engine rotation number is, the more the ignition timing ADV is delayed. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To execute stable stratified charge combustion on starting an engine. SOLUTION: In the direct injection four-cylinder engine, on starting the engine, the fuel supply device determines whether a rise timing of an REF signal of this time is of a second cylinder or a third cylinder by a S11. If the rise timing is of the second cylinder or the third cylinder, it is determined that a fuel pressure will rise from a rise timing of the REF signal by a fuel injection timing, this fuel pressure rise quantity ΔP is calculated by an S12 and then an S13 is executed. On the other hand, if the REF signal in the S11 is of a first cylinder or a fourth cylinder, ΔP=0 is set in the S22 and the S13 is executed. In the S13, a fuel pressure lowering quantity Δpl owing to fuel leakage in a high pressure fuel pump is calculated. In a following step S14, correction of subtracting the Δpl from sum of an actual fuel pressure Pr at the rising timing of the REF signal and the ΔP is preformed to calculate a fuel pressure estimation value P est at a fuel injection timing. Then, when the P est exceeds an injection allowable fuel pressure, a compression stroke injection is allowed. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce HC and enhance combustion stability at cold engine.
SOLUTION: When a fuel is injected from fuel injection valves 8, 9 into an intake passage 7, the fuel is injected two times. The first injection is performed during the exhaust stroke, and the second injection is performed during the intake stroke. The direction of injection is changed between the first injection and the second injection. In the first injection, the fuel is injected toward an intake valve 5, and in the second injection, it is injected toward an ignition plug 4 so that it is stratified around the ignition plug 4. As the combustion stability is enhanced, the ignition timing is retarded to increase the temperature of exhaust gases so that a catalyst can be early activated.

摘要： PROBLEM TO BE SOLVED: To reduce HC and improve combustion stability at a time of engine cold condition.
SOLUTION: When fuel is injected from a fuel injection valve 11 in an intake passage, fuel injection is divided into two times to perform first fuel injection in exhaust stroke and second fuel injection in suction stroke. Also, lift of a suction valve 5 is reduced and fuel injected in second injection and sucked in a cylinder from a suction valve 5 is made flow along a wall surface of a cylinder head side and is stratified around a spark plug 4. Since combustion stability is improved, ignition timing is delayed and exhaust gas temperature is raised to activate a catalyst at an early stage.
