摘要

A direct-injection spark-ignited engine is provided that includes a combustion chamber formed between a lower surface of a cylinder head and an upper surface of a piston. An intake and an exhaust valve are respectively disposed in an intake port and an exhaust port. These ports are respectively disposed on each side of the cylinder head. A spark plug is disposed in the cylinder head. A fuel injector directly injects fuel into the combustion chamber. A bowl is formed in the upper surface of the piston for generating a turbulent air flow.
