Direct cylinder injection-type spark ignition internal combustion engine |
摘要 |
A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The internal combustion engine comprises a spark plug 6, a cavity 8 formed in the top surface of the piston, and a fuel injection valve 7 for injecting fuel into said cavity in nearly the shape of a fan having a relative small thickness. A side wall 8b of the cavity opposed to the fuel injection valve for leading the fuel to the vicinity of the spark plug, has a horizontal arcuate shape which is nearly symmetrical to a first vertical plane (N1). The first vertical plane is separated away from a vertical center plane (Nc) at the center of the fuel and is nearly parallel with the vertical center plane.
