Zusammenfassung:	An apparatus comprises an internal combustion engine including an intake stream, at least one piston cylinder. An air assisted injector is configured to insert a plurality of liquid droplets into the intake stream or cylinder. The injector comprises a gas injection portion configured to deliver a gas to a mixing chamber at a first pressure and a first pulse width. A liquid injection portion is configured to deliver a liquid to the mixing chamber at a first temperature and a second pulse width, and after a predetermined delay relative to the gas so as to generate the plurality of liquid droplets having a mean diameter of up to 5 microns. A nozzle is configured to deliver the plurality of liquid droplets into the intake chamber or cylinder. The gas and the inserted liquid droplets are compressed during a compression stroke in the cylinder and fully vaporize throughout the compression stroke.
