Abstract
An opposed piston engine may include a first housing, first and second pistons, and first, second, and third fuel injector nozzles. The first housing may define a first passage extending along a first longitudinal axis. The first and second pistons may be slidably disposed within the first passage. The first, second, and third fuel injector nozzles may be in fluid communication with the first passage. At least one of the first, second, and third fuel injector nozzles may be angularly offset from another one of the first, second, and third fuel injector nozzles by an oblique angle about the first longitudinal axis.
Claims27
An opposed piston engine, comprising:
- a first housing defining a first passage extending along a first longitudinal axis;
- and
- first, second, and third fuel injector nozzles having first, second, and third nozzle axes, respectively, that are disposed in a common plane that is perpendicular to the first longitudinal axis, wherein:
- the first, second, and third nozzle axes intersect the first longitudinal axis;
- at least one of the first, second, and third nozzle axes is angularly offset relative to another one of the first, second, and third nozzle axes by an oblique angle about the first longitudinal axis;
- and
- the first, second, and third fuel injector nozzles are in fluid communication with the first passage.
