| 摘要 |
This invention discloses a combustion method, which is for internal combustion engine, which utilizes a variable spray fuel injection wherein it has (i) a variable spray angle with smaller angles for earlier fuel injection and larger angles for later fuel injection, and (ii) variable spray patterns varying from hollow conical shapes for earlier injection to multi-jet shapes for later injection, wherein it has adaptive means to distribute fuel into combustion chamber space based on background pressure and injection timing. A combustion method, which utilizes a combustion chamber which has plural number of annular inner spaces resembling the space inside an automotive tire, which provides means to control propagation paths of combustion reaction radicals and control pressure rise rate, which also provides means to promote stratification of premixed charges. An internal combustion engine utilizing the said combustion methods is also disclosed.
