DIRECT INJECTION SPARK IGNITION INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a direct injection type spark ignition combustion engine in which an air-fuel mixture is stably formed and sprayed fuel is finely atomized. SOLUTION: There is provided an internal combustion engine that is equipped with a combustion chamber 3 at a cylinder head side and performs direct injection of fuel 2 to an inside of a cylinder to burn the fuel. The combustion engine includes an intake air flow deflection means 8 for deflecting the flow of the intake air 9 sucked in the cylinder to produce the flow of the intake air 9 proceeding to a fuel injection valve 1 and the fuel injection valve 1 for performing the fuel injection against the intake air 9 deflected. Since performing injection of the fuel 2 against the intake air 9, the fuel 2 is subjected to atomization to further mix with the intake air. COPYRIGHT: (C)2005,JPO&NCIPI
