摘要： PROBLEM TO BE SOLVED: To allow spray behavior of fuel in a cylinder injection type internal combustion engine to be properly controlled, and to allow wet quantity in the cylinder (quantity of fuel adhered to a top surface of a piston, an inner wall surface of the cylinder, or the like) to be reduced.SOLUTION: A crank angle where a piston position is a reference position (a position of a cylinder volume where a tumble flow can be formed) is set as reference timing θb. When injection timing of a fuel injection valve 15 is at an advance side with respect to the reference timing θb, an air current control valve 26 is controlled such that an upstream intake passage 24 is closed and a downstream intake passage 25 is opened, so that a reverse tumble flow (an air current from an intake port 12 toward a piston 28) is formed, and fuel supply is controlled to a central direction in the cylinder with the reverse tumble flow. Meanwhile, when injection timing of the fuel injection valve 15 is at a lag side with respect to the reference timing θb, the air current control valve 26 is controlled such that the downstream intake passage 25 is closed and the upstream intake passage 24 is opened, so that a tumble flow is formed, and fuel supply is controlled to the central direction in the cylinder with the tumble flow.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of reducing a generation amount of particulate matter generated in burning of fuel.SOLUTION: A recession 33 is provided on an outer wall 303 of an injection nozzle 30 having a plurality of injection holes 31. An outside opening 313 of the injection hole 31 is formed on a bottom surface 331 of the recession 33. A side surface 332 of the recession 33 is formed to rise from the bottom surface 331. When fuel is injected by the fuel injection valve, a part of the injected fuel adheres to the vicinity of the outside opening 313 of the bottom surface 331. The adhering fuel moves along the bottom surface 331 and stays in an outer peripheral end 333 of the bottom surface 331. When the fuel injection valve performs next fuel injection, the fuel staying in the outer peripheral end 333 is blown off by the jet of the injected fuel, and is separated from the recession 33. Thus, an amount of the fuel adhering to the inside of the recession 33 is reduced. Accordingly, it is possible to reduce a generation amount of particle matter generated by burning of the adhering fuel.

摘要： PROBLEM TO BE SOLVED: To efficiently reduce a PM emission amount (amount of PM included in exhaust gas), in an engine including a fuel injection valve for in-cylinder injection and a fuel injection valve for intake port injection.SOLUTION: It is determined whether a PM emission amount detected by a PM sensor 30 exceeds an upper limit value α, during a lean combustion operation for controlling an air-fuel ratio to be leaner than the theoretical air-fuel ratio. When it is determined that the PM emission amount exceeds the upper limit value α, PM emission amount reduction control for reducing an injection ratio of a fuel injection valve 19 for in-cylinder injection and increasing an injection ratio of a fuel injection valve 18 for intake port injection is executed. Accordingly, the injection amount (amount of fuel injected in the cylinder) of the fuel injection valve 19 for in-cylinder injection is reduced, and the amount of fuel attached to an upper surface or the like of the piston 29 is reduced to reduce the PM emission amount, and the reduced amount of the injection amount of the fuel injection valve 19 for in-cylinder injection is supplemented by the increase in injection amount of the fuel injection valve 18 for intake port injection to secure the output performance of the engine 11.
