A gasoline direct injection engine may include a combustion chamber, an intake port and an exhaust port, an intake valve and an exhaust valve that open and close the intake and exhaust ports, respectively, an injector injecting fuel into the combustion chamber through an injecting hole formed at an lateral portion of the combustion chamber, an injector mounting surface having a taper structure to receive the injector therein, a seal ring that is disposed between the injecting hole and the injector mounting surface and that fixes the injector such that the injector does not extrude from an inner wall of the combustion chamber by encompassing an exterior circumference of the injector, a slanted surface that is formed around an inner circumference of the injecting hole, and is slanted in an injecting direction of the injector with a predetermined angle, and an ignition plug igniting a mixture in the combustion chamber.
