I'm pretty sure most, if not all systems use a return to tank principle. Even our old 96 Seat Ibiza D has returns from the injectors back to the tank. I can't see how a high pressure system (common rail or PD) could work without blowing up otherwise.

Is such a small engine going to have enough angular momentum to keep it spinning, even as a two stroke? During the compression/exhaust phase there's no other cylinder(s) in a power phase.

What you might be able to do is have a double acting piston with an injector either side so that the engine is always in a power phase somewhere.

Theoretically, this could give the same power as a four cylinder 4 stroke unit with just one cylinder bore.
