Abstract
Methods and systems are provided for reducing wall-wetting and improving mixing of air and fuel within a pre-chamber system of an engine. In one example, a method comprises supplying an air flow to the pre-chamber system via an air injector system while a piston associated with a main chamber is undergoing reciprocating motion. In this way, a rotating or swirling flow of fuel exiting a pre-chamber fuel injector of the pre-chamber system may be induced, which may reduce wall-wetting and improve air and fuel mixing, and when fuel is not being injected to the pre-chamber system the air flow may pressurize the pre-chamber system to reduce an amount of residuals from the main chamber to the pre-chamber system.
