Patent application show a completely new "clean sheet" engine,
designed specifically for OCP. The engine has the air compressor and
air and fuel rails built into the engine. Honda must have spent many
$$ millions $$ on the design, constuction and testing of this new
engine. It appears to be a single cylinder engine of about 1000cc.
I'm am fairly sure the patent covers multi- cylinder engines.

Air fuel injection engine

Abstract
An air fuel injection engine including an injector composed of a
fuel injection valve for injecting fuel and an air fuel injection
valve for directly injecting fuel together with compressed air into
a combustion chamber and an injector housing for holding and
securing the injector to an engine body. The injector is supported
on a head cover, and at least part of a compressed air supply
passage for supplying compressed air to the injector is provided
directly in the head cover. Further, an injector housing is formed
integrally with a head cover which forms part of an engine body.
With this configuration, the scale of the engine, the complication
of the structure around the engine, and the number of part required
can be kept to a minimum.

Have a nice day, Tom
