Abstract

A combustion method, which is mainly for internal combustion engines, either compression ignition or spark ignition, or mixed-mode engines using both compression ignition and spark ignition. The said combustion method utilizes a variable orifice fuel injector wherein it has means to produce variable spray patterns with smaller spray angle multi-jets for earlier injection(s), and larger spray angle multi-jets for main injection(s) around engine top dead center, respectively, in the same engine power cycle, wherein it has adaptive means to distribute fuel into combustion chamber space based on fuel dose and injection timings, to effectively reduce emissions and fuel consumptions. A combustion engine using the said combustion method is also provided.
