SYSTEM AND METHOD FOR ACTIVE PRE-CHAMBER IGNITION

The present disclosure provides a system and method for active pre-chamber ignition. Systems and methods for air and fuel delivery within a pre-chamber are provided. In one example, an engine pre-combustion chamber includes a first chamber portion centered along a first axis; and a second chamber portion joined to the first chamber portion and centered along a second axis disposed at an angle to the first axis. In this manner, wall wetting may be reduced, while the favorable inflation motion for robust firing may be increased. 本公开提供了"用于主动预燃室点火的系统和方法"。提供了用于预燃室内的空气和燃料输送的系统和方法。在一个示例中，一种发动机预燃烧室包括：第一腔室部分，所述第一腔室部分沿着第一轴线居中；以及第二腔室部分，所述第二腔室部分接合到所述第一腔室部分并沿着被布置成与所述第一轴线成一定角度的第二轴线居中。通过这种方式，可以减少壁润湿，同时可以增加用于稳健点火的有利充气运动。
