Got to say I have not seen air involved with any injectors on the market. But, it's been a few years since I was directly involved with anything that might make use of direct injection. Seems to me it would be a selling point and so marketing would be sure it was in the public eye. Who uses air with injectors, and what methods do they use?
The heating of the fuel in Transonic's application is not just for the sake of viscosity reduction. Heat and pressure bring it to a critical point where the three phases of matter meet (gas, liquid and solid). Upon injection into the working chamber, the rate of fuel diffusion is greatly accelerated resulting in much improved fuel mixing before the oxidation (combustion) commences. Critical point studies are a regular part of undergraduate chemistry and physics majors and become quite involved. Without foreknowledge of the science, it can become a meaningless discussion but, suffice it to say, the fuel combustion characteristics are greatly accelerated and compressed resulting in possible fuel savings and emissions reductions - characteristics which can be paralleled by HHO addition.
Air assisted injection goes all the way back to the earliest diesels. They also were used in modern gasoline production vehicles. Subaru, Honda and a few Italian makes are users that come to mind. A leader in heavy fuel air assisted injection is Orbital of Australia. You can see some of their applications in this article:
