Abstract:
An opposed piston engine includes approximately spherical combustion chamber formed by the two opposed pistons in a single cylinder and an intake manifold including gas hooks. The combustion chamber has a small cone shaped extension on each side leading to each of two opposed injectors located in the cylinder wall where the two pistons meet at the top of their stroke. The combustion chamber configuration reduces the surface area of the chamber and increases the burn length by a significant amount compared to known designs. The gas hooks in the intake manifold restrict the flow of exhaust gases into the intake manifold long enough for the pressure in the cylinder to blow down and the exhaust gasses to attain high velocity passing out through the exhaust manifold, allowing the intake ports to be uncovered before the exhaust ports.

Claim (Index 3):
The engine of  claim 2 , wherein the gas hook comprising a hook inside the intake manifold, reaching from a concave arced inner annular interior surface of the intake manifold facing the intake port, into the interior of the intake manifold and towards the intake ports, the concave arced inner annular interior surface facing the intake ports configured to reverse direction the flow of exhaust gases back towards the intake ports.
