摘要： PROBLEM TO BE SOLVED: To materialize stratified combustion poor in robustness by keeping distance between a fuel injection valve and a cavity at a time that fuel spray impinges on the cavity roughly constant even if fuel pressure varies.
SOLUTION: When fuel pressure is in a pressure correctable level range and in an injection timing correction necessary level range at a time of stratified combustion (step S11-13 affirmation), fuel injection start timing is changed based on a predetermined map to keep an impingement position of fuel spray injected from an injector on the cavity same as an impingement position at a time of standard pressure (step S14-17), injection completion timing is calculated based on injection timing corrected by fuel pressure based on the map (step 18), and fuel is injected based on those (step S19). When fuel pressure is out of the pressure correctable level range, control at a time of abnormal pressure regulation is performed (step S11 denial, step S20).

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of improving efficiency of an engine.
SOLUTION: In this engine, the shape of an intake port I is set in such a way that a circulation current of a prescribed strength or more is not formed in a cylinder C, and in the case of this intake port I, intake resistance is reduced. Since the circulation air current of the prescribed strength or more can be formed by fuel injected from a first and a second injectors 1 and 2, intake air can be sufficiently mixed with fuel. In this direct fuel injection type gasoline engine, the intake resistance is decreased to increase efficiency of the engine, while fuel can be sufficiently mixed with air, with the engine efficiency improved.
