A combustion chamber for an opposed-piston engine includes a squish zone defined between circumferential peripheral areas of opposing end surfaces of the pistons, a cavity defined by one or more bowls in the end surfaces, and at least one injection port that extends radially through the squish zone into the cavity. The cavity has a cross-sectional shape that imposes a tumbling motion on air flowing from the squish zone into the cavity.

Combustion chamber constructions for opposed-piston engines

A combustion chamber for an opposed-piston engine includes a squish zone defined between circumferential peripheral areas of opposing end surfaces of the pistons, a cavity defined by one or more bowls in the end surfaces, and at least one injection port that extends radially through the squish zone into the cavity. The cavity has a cross-sectional shape that imposes a tumbling motion on air flowing from the squish zone into the cavity. Opposing spray patterns of fuel are injected into the combustion chamber. In some aspects, the opposing spray patterns are injected along a major axis of the combustion chamber.

Fuel injection spray patterns for opposed-piston engines

A toroidal combustion chamber shape with a side injector is disclosed for an opposed-piston engine. Fuel is injected into the toroidal volume from a fuel injector in the cylinder wall. In one embodiment, fuel is injected from each injector a plurality of times with the timing between the injections such that fuel clouds from each injection remain substantially isolated from each other.
