Title: Direct injection spark ignition type internal combustion engine
Inventor: OKAMOTO SHINICHI
IPC: F02B31/00
Filed: 2003-03-04
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the discharge quantity of unburned fuel by decreasing fuel spray interfering with intake valves 5A, 5B in intake stroke injection in the case of injecting fuel from a fuel injection valve 7 disposed in the side of a combustion chamber 1 through a space between two intake valves 5A, 5B to the central part side of the combustion chamber 1.  <P>SOLUTION: In the homogeneous operation mode of performing fuel injection in the intake stroke, regardless of the cool/warm-up state of an engine, one valve stop is performed to stop one intake valve 5A in the valve closed state, so it is one intake valve 5B that the fuel spray interferes with. In the case of performing one valve stop in cooling time, a tumble control valve 9 is closed to strengthen a gas flow, thereby deflecting the fuel spray toward the intake valve 5A in the process of one valve stop. In the case of performing one valve stop after warm-up, the tumble control valve 9 is opened.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
