Abstract

In a fuel injection spray pattern for an opposed piston engine, the individual spray plumes have both radial and tangential components with respect to an injection axis (102, 114 ,121), which adds a swirl component to a spray pattern of fuel directly injected into the combustion chamber of the opposed piston engine.
