Abstract
In an in-cylinder fuel injection two cycle engine, a combustion chamber dome and a piston cavity are provided in an offset position from a cylinder bore center axis to an exhaust port side, respectively. A spark plug is mounted in a cylinder head such that its electrode is positioned in vicinity of the cylinder bore center axis in the dome. Further, a fuel injector is mounted in the cylinder head such that its injection nozzle is positioned around an outer periphery edge of the dome on the exhaust port side and fuel is injected from the injection nozzle toward the piston cavity. The piston cavity is shaped into a concavely spherical surface so as to direct injected fuel toward the electrode of the spark plug, thereby locally rich, combustible mixture being formed around the spark plug.
